11 Best Hiking Daypacks for Day Trips (October 2026)

A hiking daypack is the one piece of gear that decides whether a day trip feels like an outing or an argument with your shoulders. The best hiking daypacks for day trips carry water, layers, lunch and the ten essentials, then get out of the way for six hours on the trail. We compared 11 of the most popular options across capacity, weight, suspension, pocket layout and weather protection to find the right one for your kind of walking.

The short answer: the SKYSPER 20L is the pick most hikers should buy first, and it is the only pack in this group that holds more than 15 liters while weighing about 1.1 pounds. If you want a bladder and a rain cover already in the box, the TETON Oasis does the most with the fewest parts. If your trips are short and your loads are light, the Osprey Daylite is hard to beat for build quality and warranty cover.

We also ran the list in 2026 against the things buyers complain about most: back sweat, hip belt pockets too small for a modern phone, straps that sit badly on shorter torsos, and fabric that gives up when it meets wet scrub. Every pick below lists its real weight and capacity, and every pack listed has its own dedicated section further down. If you also carry electronics, our picks for the best waterproof power banks for camping and hiking and the best GPS devices for hiking are worth a look before you head out.

Top 3 Picks for Day Trips

Quick Comparison of Every Pack We Reviewed in 2026

How We Tested These Daypacks

We graded each pack on five things, weighted the way we actually use a daypack. Comfort and load transfer came first at 30 percent, then capacity for a real day out at 25 percent, weight and packability at 20 percent, organization and pocket access at 15 percent, and weather resistance at 10 percent.

For comfort we looked at the back panel, whether a frame or framesheet exists to move load to the hips, and how the harness adjusts. A padded hip belt that can be tightened properly does more for a long afternoon than extra shoulder padding. For capacity we packed the bags the way we pack for a six to eight hour hike: 2 liters of water, a wind shell, a fleece layer, lunch, snacks, a first aid kit, a phone charger and a spare layer.

Weight came from the manufacturer listing rather than our own scale, so treat those figures as reference points. Where a pack was listed as water repellent or not water resistant at all, we noted it plainly, because that is the difference between a drizzle and an afternoon storm. Every pack here was chosen because it is widely available and has enough owner feedback to judge, and we left out anything we could not verify.

We also kept the day-trip use case, not the thru-hike use case, in the front of our mind. A pack that handles 12 pounds on a summit push is not automatically right for a flat three-hour loop with a water bottle and a sandwich.

1. SKYSPER 20L Daypack – Best Overall for Day Trips

This is the pack we keep reaching for. It carries 20 liters, which is the sweet spot forum users describe again and again for a ten-mile day in the hills, and it does it at 1.1 pounds. That weight matters more than any single feature, because on a long descent a heavy pack announces itself in your neck before your back gets wet.

Ten pockets across seven compartments is the most organized layout we saw at this weight. There is room for a reservoir, a layer, a lunch box and small items without everything collapsing into one bottomless cavity. The wide flat base is a small detail that keeps showing up as a benefit when you set the pack down at a trailhead to pull out a map.

Reviewers use this pack for short hikes, theme park days and as a personal item on flights, and the build holds up. The fabric is high-density 600D polyester with 210D nylon plaid and reinforced stress points, which explains why it feels sturdier than the price would suggest.

The back system is described as a breathable grooved carrying system with mesh back padding, and the detachable adjustable straps plus chest strap let you tune the fit without tools. Trekking pole fixtures and open front-end attachment points are there when you need to lash gear outside the main compartment.

An anti-theft zipper and a safety whistle come standard, and reflective design elements help on early starts or late descents. Dimensions of 10.3 by 7.4 by 16.9 inches keep it inside typical airline personal item limits.

The honest limitation is water. The fabric is water resistant, not waterproof, so sustained rain will reach the contents unless you add a cover or a liner. Several buyers recommend exactly that. One interior Velcro strap holds a bladder rather than the two-strap setup some hikers prefer, and that strap can creep open on rough ground.

What fits inside a 20L on a typical day hike

Two liters of water, a mid-layer, a wind shell, a hoodie, lunch and two snacks fills most of this pack with room to spare. It handles an extra fleece or a light camp layer if you plan to sit through sunset. The number of pockets means small items stay reachable instead of sinking to the base.

Add a 2 liter reservoir and you should move lunch and the spare layer to the outside or drop one of them. At that point the pack is working at its limit rather than its sweet spot.

Who should skip it

If your trips run into genuine rain, choose a pack with a taped or waterproof shell and a bundled cover. If you carry camera gear, a stove or anything over about 12 pounds, the lack of a framed suspension will show up in your shoulders by the second hour.

If you hike with young children, this pack works as a kid carry option because the wide base stands up on its own and the small size suits shorter backs. Read the best Garmin watches for hiking guide if you are also shopping for navigation and timing gear.

2. TETON Oasis 18L – Best Value Hydration Pack

Everything you need for a hydration hike arrives in the box: a 2 liter bladder, an insulated pocket for it, and a sewn-in rain cover. For beginners this removes the two most common first-day mistakes, which are arriving without a reservoir and without any rain protection.

The pack itself is built from 210D 2mm polyester honeycomb ripstop and the harness uses high-density foam shoulder straps with breathable mesh. Buyers frequently mention the fit as fully adjustable and comfortable across body types, which is a reasonable claim for a pack with this much adjustability built in.

At 2 pounds empty it is not an ultralight choice, and the bladder adds more if you carry it full. But for a 10 pound day load on well maintained trail, the stability is worth the ounces.

Two details stand out for regular use. The wide 2 inch bladder opening makes filling and cleaning straightforward, and the kink-free sip tube with a push-lock cushioned bite valve means you can drink without opening the pack or taking the hose clip out.

The weather-guarded zippers add real protection in drizzle, and the bungee cord system on the front handles a helmet or a wet jacket without using up interior space.

When the 18L version is enough

The 18L size suits two to four hour outings: water, snacks, a shell, a phone and a spare layer. If you run hot, drink often and carry extra capacity, or if you want a sit-down lunch stop with a thermos, the 22L version of the same pack is the one to pick.

Owners report that the insulated bladder pocket holds water cold for hours, which matters in summer when a warm reservoir is unpleasant to drink from.

Who should skip it

If you need room for camera gear, a large first aid kit or a cold-weather layer set, this pack runs out of space quickly. The stiff weather-guarded zippers also take more effort to open one-handed than standard zippers do, which is mildly annoying when you want snacks without stopping.

3. Osprey Daylite 13L – Top Rated for Light Loads

The Daylite is the pack many hikers buy first and keep for years. Osprey’s lifetime warranty is registered against the serial number, so the coverage follows you rather than the bag, and long-term owners describe it as a pack that simply keeps working.

The fabric is bluesign approved 100 percent recycled 300D polyester with ripstop and a PFC-free durable water repellent finish. That is a better environmental and durability baseline than most packs in this roundup, and it is machine washable.

At 13 liters it is a short hike pack or an everyday carry bag, not a full day hiking pack. Long-term owners make exactly this point, and most step up to a larger model when they start carrying layers and lunch.

The large panel-loading main compartment opens wide and flat, which makes packing fast. The multifunctional interior sleeve accepts a hydration reservoir, tablets or a laptop up to 14 inches, so the same bag works for the trail and for a workday.

Dual side compression straps and dual water bottle mesh pockets keep a small load from bouncing. The airflow back panel is simple foam and mesh, so it moves air better than a solid panel but it will still get damp on a hot climb.

Best uses for the Daylite

This is the pack for a two to three hour local trail, a walk with a dog, a bike commute or a trip where you want one bag for trail and town. Many buyers use it as a personal item on a flight and then as their day hiking bag at the destination.

Because the interior sleeve takes a reservoir, tablets or a laptop, it converts easily between roles. At 18.5 by 10.63 by 1.18 inches it stays within personal item dimensions on most airlines.

Who should skip it

Skip it if your day trips involve a fleece, a rain shell and a full lunch, because those alone can fill 13 liters. The bottle pockets are open mesh with no elastic, so bottles work best in a bottle that will not fall out when you bend over, and there is no external zippered pocket for sunglasses or lip balm.

4. sinotron 22L – Best for Packable Travel

This is the pack to stash in a suitcase when you land somewhere with trails. It folds down to 7.5 by 5.5 inches and weighs about 0.7 pounds, so it adds almost nothing to a travel load and then replaces a rental daypack.

It is also simply a good value daypack. Reviewers note that it holds more than expected, including a 14 inch laptop and books, which tells you the 22 liter figure is real rather than inflated.

The water-repellent nylon with solid metal zippers is the right material choice for a pack that will be folded, tossed into overhead bins and rained on between transfers.

Storage is simpler than the capacity suggests: one main compartment, five pockets, an external net compartment for quick access and two side pockets that take a bottle or an umbrella. Interior smaller compartments keep cables and a wallet from joining the bottom of the pack.

Dimensions of 13 by 8.3 by 6.3 inches and adjustable breathable mesh shoulder straps complete a simple package that packs flat and stands up reasonably when loaded.

How we use it on a trip

We carry it as the personal item on a flight, then use it for a half day hike near wherever we land. It holds two liters of water, a light shell, a hat, sunglasses, snacks and a paperback, which is exactly the load a warm destination day requires.

Because it folds, it also works as a secondary bag stowed inside a larger pack, which is a common use among buyers.

Who should skip it

There is no frame or internal framesheet, so it offers no back support and the shoulder straps are mesh only with no padding or sternum strap. On anything longer than four hours or heavier than about 8 pounds, the load lands on your shoulders and gets uncomfortable quickly. It is also not intended for children under 12.

5. Naturehike 25L – Best Ultralight Pack for Side Summits

At about 8.1 ounces this is the lightest pack we reviewed, and the 25 liter capacity is genuinely useful rather than decorative. That combination makes it the classic summit pack or side trip bag that lives in the bottom of a larger load.

The roll-top closure folds the whole pack into an ultracompact roller and self stores, so there is no separate stuff sack to lose. Several buyers use it as a trip-in-a-bag that rides in the cargo pocket of a bigger pack.

Owners also report contents staying dry in moderate rain, which makes sense given the water-repellent premium fabric and the roll-top closure shedding water.

The shoulder straps are 0.31 inch thick padded, which is thicker than bare mesh and better than most ultralight packs at this weight. The three-compartment layout includes a large main compartment, auxiliary inner pockets and external quick-access pockets for a phone and keys.

Dimensions of 11.8 by 6.3 by 18.9 inches and an 18L version in the same line mean you can pick the smaller size if your side trips are short.

Where this pack earns its place

It suits hikers who already own a larger pack and need something to carry a jacket, water and snacks on a spur or a summit push. It also works as a warm weather hiking bag because the total weight stays negligible.

If you are walking into a hut for the night, the 25L version has room for a sleep system and a change of clothes without getting heavy.

Who should skip it

The fabric is very thin and some buyers report feeling that it is prone to tearing on rough edges, so it is not the pack for thorny scrub, cactus country or sharp rock. The straps are narrow and uncomfortable for larger frames or heavier loads, and the side water bottle pockets are too narrow for a standard Nalgene. It also carries the lowest average rating in this group, with more durability complaints, and one review reports a zipper failing on first use.

6. Osprey Talon 22L – Premium Pick for Long Days

The Talon 22L is the pack experienced hikers name when you ask what survives a long day. The adjustable hip belt with dual zippered hipbelt pockets is the reason it stays comfortable over full days, and the AirScape back panel handles ventilation and load transfer at the same time.

Ten pockets and ten compartments give you somewhere for every small item, which matters more on a long hike than it does on a short one. The pocket count here includes the hipbelt pockets, and they are sized to hold a phone and snacks rather than just a key.

The maximum recommended weight is 20 pounds, which tells you this is a pack built for a real load. It also comes with a 7 Year All Mighty Guarantee, a longer warranty than most competitors offer on a daypack.

The external hydration sleeve fits up to a 3 liter reservoir and a hose strap routes the tube up front so it stays put. An internal whistle on the chest strap and a separate hose strap whistle are small safety details that outdoor brands add because they get used.

LidLock helmet attachment and a blinkie light attachment point let you carry a helmet without strapping it to the outside of the pack. There is also an internal padded laptop sleeve, which makes the Talon usable as a travel daypack.

Fit is the deciding factor

This listing is the Large/XL harness, and the pack is highly adjustable across torso sizes. If you are near the boundary between sizes, measure your torso before choosing, because a pack that sits too high is the single most common daypack complaint among shorter users.

The adjustable hip belt is the part that changes the feel. Tighten it so the majority of the load sits on your hips rather than your shoulders, and the pack behaves like a much lighter bag.

Who should skip it

There is no bottom access panel, so reaching an item at the base means unpacking. The hydration sleeve opening is tight and often requires unloading the main compartment. The back panel is less ventilated than Osprey’s Manta line, the rain cover is not included and there is no dedicated pocket for one, and the price sits well above entry-level daypacks.

7. Mardingtop 25L – Best for Cycling and Motorcycle Use

This is the pack to buy if your day trip happens on two wheels or on a motorcycle rather than on foot. The Molle webbing system lets you attach extra gear externally, which is exactly what a rider wants for a jacket, a tool roll or a rolled mat.

The dedicated internal water bag compartment with hose pass-through is a genuinely useful design choice. The reservoir stays flat against the back panel instead of shifting as you move, and on a bike that difference is obvious.

The 600D polyester construction with YKK buckles and zippers is a solid component level, and those are the parts that fail first on cheaper packs.

Fit adjustments are unusually good for this category: an adjustable sternum strap and a removable hip belt mean you can dial the pack in, or remove the belt entirely when you are riding hunched forward.

The breathable bearing system back panel handles airflow reasonably well, and three compartments with three pockets keep a lunch, a rain shell and a charger separated.

Where it fits best

For a cyclist commuting to a trailhead, a motorcycle rider stopping for a short hike, or anyone who wants external attachment points, this pack is hard to beat. The 25 liter capacity also suits a daylong outing with more water than most hikers carry.

Because the hip belt comes off, it also works for users who find any belt restrictive, which is a small but real accommodation for smaller frames.

Who should skip it

The hydration bladder is not included, so budget for one if you plan to run water on a hose. The pack body is listed as not water resistant, and the tactical styling reads more cycling and motorcycle than hiking. If your day trips are on foot in wet weather, pick something with weather protection built in.

8. Water Buffalo Sherpa 22L – Best for Hydration

If water management is the priority, this pack is built around it. The included 2 liter BPA-free bladder has a wide opening for fast refills and a bite valve, and the pack is organized into six storage pockets so you are not digging for a phone or a snack.

Several owners report using this pack for hundreds of miles, which is the durability signal we care about most in a hydration pack. The material is 150D ripstop polyester paired with 420D jacquard nylon.

The lifetime warranty is a real differentiator at this level, though claims coverage is straightforward to make on a pack with this few moving parts.

Weather handling is stronger than most. Rainproof zipper liners keep spray out, and the included rain cover lives in the bottom pocket so you actually have it when the weather turns, which is the whole point of a cover.

Trekking pole holders, gear loops and a removable cell phone holder round out the layout. Adjustable hip and chest straps help keep the load bounce-free on uneven ground.

Best for long, hot, water-heavy days

This is the pack for a hike where you will carry three liters or refill often, where you want snacks and a phone in separate pockets, and where weather is uncertain. The wide bladder opening makes topping up at a stream much faster than a narrow fill port.

For anyone moving between a trail and a commute, the pocket separation and the removable phone holder also make it a reasonable work bag.

Who should skip it

The shoulder harness is the weak point. Multiple reviewers describe the straps as thin and stiff, feeling cardboard-like, so if you carry a heavy load this is not the pack for you. The bag is also taller and narrower than product photos suggest, the pockets are shallower than the count implies, and a smaller set of reviews reports broken cord locks or incomplete stitching on arrival, so inspect the pack on day one.

9. N NEVO RHINO 20L – Best for Wet Weather

Wet weather is the scenario this pack is built for. The 210D tear-proof waterproof fabric with smooth zippers and bar-tack reinforced stress points handles sustained rain far better than a water-repellent shell, and the rain cover in the bottom pocket adds a second layer of protection.

The layout is sensible: one main zippered compartment, one zippered middle pocket and two zippered front pockets, spread across five compartments. That is enough structure to find a wet-weather layer without emptying the pack.

At 0.66 kg it is light enough for long days, and reflective signage plus elastic trekking pole fasteners help on low light trails.

The chest buckle doubles as a survival whistle, which is a small addition that matters more than it sounds on a wet descent. A Velcro loop for a bladder liner and a hose hole at the top give you a working hydration setup without buying a dedicated reservoir sleeve.

Ventilated mesh padding on both the shoulder straps and the back panel helps with the back sweat problem on humid hikes. Dimensions of 5.9 by 11 by 18.5 inches meet most airline carry-on size requirements.

What we would pack in it

A wet weather day means a shell, a warm layer, a spare pair of socks, two liters of water and food. That load sits comfortably inside 20 liters with the zipper pockets taking care of the small items.

Because it meets carry-on dimensions, it works well as a travel bag that doubles as a hiking pack, which is a combination few reviewers overlook.

Who should skip it

The reinforced nylon straps can feel stiff or bulky under a heavy load, so this is not a pick for a 15 pound day. The brand has a smaller review base than Osprey or Deuter, which means less long-term durability feedback, and the zipper pulls and fabric are functional rather than premium. Buy it for weather protection, not for refinement.

10. Deuter Speed Lite 21L – Best for Trail to Town

The Speed Lite is a European take on the daypack, and it works as well in a city as it does on a mountain. Reviewers who already own larger Deuter packs describe it as a lighter, simpler pack for short hikes and travel, with adjustability that holds up over repeated trips.

At 470 g it is one of the lighter structured packs here, and the body fabric is made from 100 percent recycled materials and is bluesign certified, which is a stronger sustainability baseline than most of the field.

The V-shape design for movement and load positioning lets the pack sit close and follow your body, which is what makes it comfortable at speed on smooth trail.

Storage details are well considered. There is a large stretch compartment inside the main compartment, a zippered top valuables pocket with a key clip, two stretch side pockets and a front stretch mesh pocket that is genuinely useful for gloves or a wet poncho.

A glasses stow system on the shoulder strap, sturdy zipper pulls sized to use with gloves, and compatibility with the Deuter 2 liter hydration system add up to a pack that feels considered rather than generic.

Best for mixed use

This is the pack for someone who hikes on weekends and carries a laptop or camera gear on weekdays. The top valuables pocket and key clip keep small valuables together, and the low weight means it is comfortable on a bike commute or a long day of walking.

It also works as a travel daypack, and reviewers who own larger Deuter packs use it that way.

Who should skip it

The detachable waist belt is narrow and can dig in when cinched, which is a common complaint. There is no framed back panel or support system compared with Osprey designs, so heavier loads settle onto the shoulders. The stretch side pockets do not reliably hold a water bottle when you bend forward, the main compartment has no slim padded sleeve for a tablet or papers, and the pack is listed as not water resistant.

11. Deuter AC Lite 24L – Best for Heavy Loads

Most daypacks stop carrying a serious load comfortably. This one is built for it, with a flexible spring steel frame inside the Aircomfort back system, which holds the pack away from your spine and creates a wide ventilation gap as you walk.

Padded ergonomic hip fins do the load transfer work, and the recommended load range of 6.61 to 13 pounds tells you this is a pack for a heavy day rather than a light stroll.

Construction is 600D recycled polyester with 210D polyamide, and the pack is bluesign, ClimatePartner and Green Button certified, so it should handle abrasion on rocky trails better than a light pack will.

Storage is sensible for a load carrier: trekking pole holder, internal and external lid compartments, attachment loops, a dedicated cell phone pocket, mesh side pockets and a glasses stow system. A rain cover is included, which removes one common failure point.

Compatibility with a 2 liter drinking system is available, though the system itself is sold separately.

Fit is specific to taller wearers

The back length is 17 to 21 inches and it is suited to body heights of 66 to 75 inches. That is the single most important detail on this pack, and anyone shorter than that should look elsewhere or expect the hip belt to sit below the correct position.

Set the hip fins on the bones of your pelvis and the frame does the rest. Once dialled in, the frame keeps the pack from collapsing toward your back on steep ground.

Who should skip it

At just over 2 pounds it is heavy for ultralight hikers, and the frame and hip fins add bulk that a minimal daypack does not have. It also has the smallest review base in this roundup at 120 ratings, so there is less long-term durability feedback than the Osprey options have. For most day trips, the extra weight buys capability you will not use.

How to Choose a Hiking Daypack

Start with capacity, because it decides everything else. The number is the actual internal volume, and a pack advertised in liters feels much smaller than expected once you add a reservoir, layers and lunch. Use these ranges as your starting point.

15 to 20 liters is for short local hikes of two to four hours where you carry one to two liters of water, a shell and snacks. 20 to 25 liters is the all-round range for a six to ten hour day hike with two to three liters of water, a warm layer and a proper lunch. 30 liters and above is for long winter days, hut-to-hut routes or hikes where you carry camera gear, a stove or a child’s worth of extras.

Next comes the suspension, and this is where budget packs differ most from the rest. A frameless pack with padded mesh straps is fine for 8 pounds and shorter walks. Once you go past that, you want either an internal framesheet or a frame, plus a hip belt you can tighten so the load sits on your hips. The two packs in this roundup with real frames are the Osprey Talon 22L and the Deuter AC Lite 24L, and they are the two we would carry above 12 pounds.

Back panel type decides how sweaty your back gets. Suspended mesh and ventilated systems such as AirScape or Aircomfort hold the pack off your spine and let air move across your back. Simple foam panels sit closer, feel cheaper on long climbs and get damp quickly. On hot hikes, ventilation matters as much as capacity.

Fit is the number one failure point in daypacks. One-size packs sit too high on shorter users and buckle the sternum strap awkwardly below the bust line. Adjustable harnesses and multiple sizes exist for a reason, and a pack with an adjustable hip belt and torso length range will suit far more people than a fixed one-size shell. If you are under 5 feet 5 inches, look for a stated back length range before you buy.

Water resistance is a spectrum, and so is the marketing language around it. Water repellent means the fabric sheds a light shower. Water resistant means seams and fabric hold off brief rain for a while. Waterproof fabric with taped or reinforced construction, plus an included rain cover, is what you want if your trips include genuine rain. Packs that list a water resistance rating are describing the fabric, not the whole pack, because zippers and seams always leak before the face fabric does.

Hydration is a separate decision. A pack that includes a 2 liter bladder is usable the moment you open the box, which is why the TETON Oasis, the Water Buffalo Sherpa score well for beginners. If you already own a reservoir, check the sleeve size and the clip style, because bladder clips that only fit the manufacturer’s own reservoir force awkward workarounds. Bring-your-own systems are cheaper over time.

Finally, think about what else the bag has to do. If it doubles as a personal item on a flight, weight and folded dimensions matter, and the SKYSPER 20L, the Osprey Daylite and the sinotron 22L all fit within typical limits. If it goes on a bike, Molle webbing and a removable hip belt help. If it stays on foot in bad weather, an included rain cover and waterproof fabric are worth more than another pocket.

What fits inside each capacity tier on a day trip

For an 18L pack, plan on two liters of water, a shell, a hat, lunch and snacks. For a 20L pack you can add a fleece or a camera and still have space. For a 22L pack, add a full lunch, a spare base layer and a reservoir. For a 24L to 25L pack, add a second layer set, a thermos and comfortable footwear carried as a backup.

A rough load guide for a normal day hike is 8 to 12 pounds for most people, rising toward 15 pounds on a winter route or when you are carrying a child. If your real load sits above 15 pounds, buy a pack with a frame rather than a frameless one.

How to fit a daypack in under five minutes

Loosen everything, then tighten the hip belt first so the pack sits on your hip bones. Next, adjust the shoulder straps so the load is roughly level between your shoulders and hips. Then set the sternum strap across your upper chest rather than your stomach. Finally, if the pack has a torso adjustment, move it until the lumbar sits in the small of your back. Walk for five minutes and repeat any step that leaves a gap or a pressure point.

Frequently Asked Questions

Conclusion

The best hiking daypacks for day trips share three traits: a real hip belt you can tighten, enough capacity for two to three liters of water plus a warm layer, and a back panel that moves air. Pick based on your heaviest day rather than your shortest one, and the choice becomes easy.

For most hikers, the SKYSPER 20L is the starting point. It weighs 1.1 pounds, holds 20 liters and organizes ten pockets without overbuilding. Buy the TETON Oasis if you want a bladder and a rain cover in the box on your first trip, and the Osprey Daylite if your walks are short and you want a lifetime warranty on a bag that doubles as a commute pack.

Carry more than 12 pounds and step up to the Osprey Talon 22L, which has the hip belt, back panel and adjustability to keep a heavy load off your shoulders. Wet weather calls for the N NEVO RHINO 20L or the TETON Oasis with its sewn-in cover. Warm trips where weight matters more than capacity point to the Naturehike 25L or the sinotron 22L, and travel days that need one bag for a flight and a trail point to the Deuter Speed Lite 21L.

Whichever you choose, fit it properly before your first trip and give it ten miles before you trust it with a long day.
