A backpacking rucksack is a bit of a chicken-and-egg item. When packing, do you choose your other kit first, or your rucksack? Gear choice influences the rucksack you’ll need, and rucksack choice influences the gear you can comfortably carry. Put another way, choosing the right rucksack is an important decision!

Most of us will end up with several packs and that’s because it’s hard to find one that will do everything well. Many TGO readers who are into backpacking are interested in multi-day routes with a rugged flavour… even if our lives don’t always allow for that! Some of us opt for a lightweight approach in the hills, but there’s always a place for bigger packs, especially in winter, or when planning for bucket list expeditions abroad.

Whatever your style, a backpacking pack must be big enough for hillwalking as well as food and camping equipment. It must be durable, comfortable to carry, and have convenient storage options such as side and front pockets, as well as attachment points for items such as ice axes and trekking poles. For winter use, you’ll likely want more durable materials, bigger capacity, and more strap attachment points for skis or snowshoes.

Beyond this, personal preference plays a hefty role, and that’s why we’ve selected rucksacks in a range of designs from minimalist, lightweight models to full-featured packs designed for massive loads. We have decided not to test 40L models (more suitable for overnight trips in good weather, or genuinely ultralight loads on longer trips) or anything bigger than 65L (likely too big for most people).

Our backpack testers live in Scotland and spend much of their time up big hills in all weathers. If a rucksack performs well for five days in the Cairngorms then it’ll likely do okay everywhere.

Lowe Alpine Airzone Trek ND 43:50L 

Lucy Wallace’s Best in Test

This roomy but low-volume pack has just one downside.
Pros
  • lightweight
  • tough
  • loads of handy features
Cons
  • back system can’t be adjusted when bag is full
Quick Specs
Price: $180 / £180
Weight: 1645g
Materials: polyester/nylon mix (8% recycled content), PFAS free
Features:
adjustable Airzone back system, zipped hip and lid pocket, internal lid pocket, mesh side pockets, mesh stash pocket, internal divider, pouch for hydration system, side compression straps, zipped lower entry point and bottom straps, trekking pole TipGripper attachments
Volume: 43l
Sizes: one size, adjustable
Women/Mens version: Airzone trek 45:55l
lowealpine.com

At just 43 litres, the Lowe Alpine Airzone Trek ND 43:50l was the lowest volume pack that I tested, but I found it to be easily roomy enough for an overnight camp, even with a winter sleeping bag. The lid is fixed, but has good extension capabilities, and there are plenty of compression straps for attaching external items if necessary. I would be confident using this in summer for a couple of nights camping (with careful packing) and for extended hut to hut journeys. Despite its relatively low weight, it is rugged, well made, and festooned with useful features, including an internal zipped lid pocket and a roomy external stash pocket.

My only complaint is the internal adjustment for the back length, which is a hook and loop tab system buried deep within the hydration pouch. It’s nigh on impossible to adjust when the pack is full, but it’s only when it is properly loaded that you can effectively tailor the fit. Getting the rucksack adjusted for the first time is frustratingly time consuming, because what should take seconds takes several minutes of faff.

The Notch is the newest addition to the Atom Packs range, designed for lightweight but not ultralight three-season loads, and sits between existing models The Atom and The Prospector (formerly The Mo).

It’s a superb choice for three-season lightweight backpacking thanks to well-considered design choices, full customisation, and fantastic hand-made build quality from a UK brand. In use, I’ve found The Notch to be flawless. The minimalist design is well suited to experienced users; if you’re used to packs with more features it may need a short adjustment period, but the weight/capacity/comfort ratio really is unbeatable.

I’ve found it perfect for three-season trips with a bit more gear, or even lightweight winter missions. Even with heavier loads, I haven’t missed the load lifters. Plenty of external storage makes it great for carrying wet tents, ice axes, camera tripods, or multiple water bottles. Overall, this is a pack for the lightweight connoisseur and near perfect in its class.

Greener Choice

Fjällräven Kajka 55

Alex Roddie’s Greener Choice

Overall, despite the high weight, I think this is a great choice for backpacking in deep winter conditions. It’s overkill for most three-season backpacking, though.
Pros
  • superb adjustable harness for heavy loads
  • great for winter or expedition use
  • durable design
  • loads of attachment points & pockets
  • recycled fabrics
Cons
  • complex design overkill for some uses
  • very heavy
Quick Specs
Price: $395.92 / £360
Weight: 2810g (S/M)
Materials: Vinylon F, recycled 500D and 210D polyamide, traceable wood
Features:
zipped front access to main compartment, compression cordage on lid, dual ice axe fastenings, long side compression straps for attaching items to front, hydration sleeve, detachable rain cover, load lifters
Volume: 55 litres (other capacities 35 to 100 litres)
Closure: detachable zipped floating lid
Back: adjustable, breathable mesh, with external birch wood frame
Hipbelt: cushioned, adjustable, 6 inches
Pockets: large lid pocket with additional internal and external zipped pockets, 4 side pockets (2 zipped), 2 zipped hipbelt pockets
Sizes: S/M, M/L
Women/Mens version: no
fjallraven.com

The Fjällräven Kajka 55 is a durable, full-featured pack designed for extended treks. It has an innovative external frame made from birch wood, said to reduce the product’s overall carbon footprint by 10%, and has the most adjustable harness of any men’s pack tested. The harness is the best-padded of any of the packs I tested, and combined with its high level of adjustability (as well as really long straps) you can achieve a superb level of comfort, no matter your body shape or size. It’s so comfortable that massive winter loads felt kilos lighter than expected.

I’ve found it fantastic for multi-day, high-level winter routes in the Cairngorms and Austrian Alps. Tent and snowshoes can be strapped easily to the outside. The wooden frame is one reason for its weight. Birch wood is heavier and bulkier than aluminium, but it’s more sustainable and performs well. It looks and feels good too. Another note on sustainability: the polyamide fabrics are recycled, and the product is made without PFAS.

Overall, despite the high weight, I think this is a great choice for backpacking in deep winter conditions. It’s overkill for most three-season backpacking, though.

Osprey Renn 50

Osprey Renn 50 review

Lucy Wallace recommends

Overall, I found the pack comfortable to carry, with good weight distribution, and easy to pack.
Pros
  • tough
  • lightweight
  • less expensive than some
Cons
  • fixed lid
  • no internal lid pocket
  • no large external stash pocket
Quick Specs
Price: $180 / £170
Weight: 1626g
Materials: 100% recycled 600D polyester, and recycled nylon; PFAS-free; DWR treatment
Features:
tensioned adjustable Airspeed back system, zipped hip and lid pocket, mesh side pockets, rain cover, internal divider, pouch for hydration system, side compression straps, zipped lower entry point and bottom straps
Volume: 50l
Sizes: one size, adjustable
Women/Mens version: Rook 50
osprey.com

The Osprey Renn 50 impressed me in several ways. At just over 1.6 kg, it’s lightweight compared to many competitors in its class, yet it doesn’t compromise on quality. The 600D polyester fabric is tough, and is made from entirely recycled sources, which makes it a reasonable environmental choice. The pack is significantly less expensive than Osprey’s other models, yet the build quality is exactly what you’d expect from a premium brand. Some of the weight savings come from its stripped-down design.

Overall, I found the pack comfortable to carry, with good weight distribution, and easy to pack. I unfastened the buckles on the internal divider to allow me to fill every corner of the base. There’s a zip for easy access to the bottom of the pack which is ideal if like me you tend to store the tent and other camping gear near the base.

With a 50-litre volume, I found the Renn 50 is ideal for an overnight camp or perhaps a couple of days if packing light. The side pockets are roomy, and the hip belt pockets are large enough to accommodate my mobile phone, even with its carry case.

Highlander Novar 50+5l

Highlander Novar 50+5 review

Lucy Wallace’s Best Value

It’s inevitable that there will be a trade-off between price and build quality, but it is impressive that Highlander have managed to include so many features for the price.
Pros
  • budget option
Cons
  • less comfortable
  • not as durable
Quick Specs
Price: £95 (not available in the US)
Weight: 1857g
Materials: ripstop nylon
Features:
tensioned back system, zipped hip and lid pocket, mesh side pockets, mesh front pocket, rain cover, pouch for hydration system, side compression straps, zipped lower entry point and bottom straps
Volume: 50+5l
Sizes: one size, adjustable
Women/Mens version: Unisex
highlander-outdoor.com

The Highlander Novar 50+5 comes with lots of useful features – mesh pockets on the side and front, and generous zipped hip pockets. There are even ice axe loops on the base, which means that it can be used in all seasons.

Inside the lid there is useful information about what to do in an emergency. At £95, it’s very much at the budget end of the market and will be attractive to Duke of Edinburgh participants. It’s inevitable that there will be a trade-off between price and build quality, but it is impressive that Highlander have managed to include so many features for the price.

The Novar has an old-fashioned adjustable back system based around two metal stays and buckles that allow the height of the shoulder straps to slide up and down the stays. It’s very simple to adjust and longitudinally rigid but has a habit of flexing and rocking when fully loaded, so is less stable and comfortable than others in this roundup.

Kelty Glendale 65l

Kelty Glendale 65L review

Alex Roddie’s Best Value

The value is great and it’s a durable pack for hard use. It should last well.
Pros
  • comfortable harness
  • good value
  • bottom straps for tent
Cons
  • no spindrift collar on main compartment
  • few attachment points for compression cordage
Quick Specs
Price: $239.95 / £209.99
Weight: 2200g
Materials: 300D Velocity (nylon), 600d Polyester Oxford
Features:
side access to main compartment, bottom access to main compartment, hydration sleeve, botom compression straps, large front grab handle, PFAS-free DWR, load lifters
Volume: 65 litres
Closure: zipped floating lid
Back: adjustable, breathable mesh & ventilated, with external & internal frame
Hipbelt: cushioned, adjustable, 5 inches
Pockets: 2 stretch mesh on harness, large lid pocket with internal zipped mesh pocket, large front stretch mesh pocket, 3 side pockets (1 zipped), 2 hipbelt pockets (1 zipped, 1 open mesh)
Sizes: one size
Women/Mens version: yes
kelty.com

The Kelty Glendale 65L is a capacious and durable pack with a good range of features, best for traditional backpacking loads. However, its lack of spindrift collar and poor ice axe attachments make it less than perfect for winter use. The Glendale 65L has a traditional feature set, including compression straps at the bottom for attaching a tent, bottom zip access, a large floating lid, and beefy harness.

However, it also has asymmetric pockets – there’s a large side pocket on one side, while on the other a similar-shaped zip allows access to the main compartment. The hipbelt pockets are also asymmetric, with the one on the left side being mesh. You get side compression straps (extendable enough for poles but not a tent) and side bottle/wand pockets. The front mesh pocket is much smaller than on some of the other packs tested. The harness is highly adjustable and comfortable under heavy loads – a real plus point of this pack.

In use, I found the pack great for carrying as much gear as I could stuff in it, but the lack of a spindrift collar is a disappointment, which means your gear risks getting wet in rainy or snowy conditions. The ice axe attachments also feel much less secure than the usual design. Otherwise, the value is great, and it’s a durable pack for hard use. It should last well.

Gregory Maven 55

Gregory Maven 55 review

Lucy Wallace’s verdict

This pack is impressively spacious for its size and stated volume with a brilliant floating lid.
Pros
  • lightweight
  • roomy
  • well-featured
  • two sizes available
Cons
  • bulky shoulder straps
  • lightweight fabric
Quick Specs
Price: $194.96 / £220 – available from Cotswold Outdoor

Features:
adjustable back system, zipped hip and lid pocket, mesh side pockets, rain cover, internal divider, pouch for hydration system, side compression straps, zipped lower entry point and bottom straps, floating lid
Volume: 55l
Sizes: XS/S and S/M
Women/Mens version: Paragon range
eu.gregorypacks.com

The Gregory Maven 55 is a great mix of features and low weight, but it does come with a couple of caveats. This pack is impressively spacious for its size and stated volume. Its wide design makes packing easy, and it is loaded with generous pockets – mesh ones on the sides and front, plus two zipped pockets in the lid and extras on the hip belt.

The Maven is versatile enough for multi-day trips in the mountains, especially if you’re using lighter weight, less volumous gear. The pack comes in two back lengths, which should in theory allow for a tailored fit. The back system is easily adjustable in seconds thanks to a hook-and-loop fastening. However, the fit is where I ran into problems.

The shoulder straps are stiff and bulky and the contouring wasn’t quite right for me, and so were quite uncomfortable. Otherwise, the rest of the harness and back system performed well, transferring the load effectively to the hip belt.

Rab Muon 50

Rab Muon 50 review

Alex Roddie’s verdict

If you’re looking for a pack that can do double duty, covering general backpacking with faster-paced adventures then this is worth a look – but try it on first.
Pros
  • comfy running-style harness
  • good stability
  • fairly light
  • good value
Cons
  • only one back length and non-adjustable
  • bottom compression cords are awkward
  • limited stretch in front pocket
  • no hipbelt pockets

Price: $298 / £220
Weight: 1050g
Materials: 85% recycled 100D high-tenacity ripstop nylon
Features:

Volume: 65 litres
Closure: detachable zipped floating lid
Back: fixed, ventilated, with internal frame
Hipbelt: cushioned, ventilated, adjustable, 5 inches
Pockets: 2 zipped stretch mesh on harness, large lid pocket, mesh pocket under lid, large front stretch mesh pocket, 2x large side mesh pockets
Sizes: one size
Women/Mens version: yes
rab.equipment/uk

The Rab Muon 50 is a pack inspired by running vests, but designed for lightweight backpacking. With a comfy harness that keeps the load close to the body, it’s good for scrambling and could be used for fastpacking. However, the non-adjustable back only comes in one length, and a few design niggles make it less than perfect.

That harness is the headline feature. It’s honestly pretty great, with broad shoulder straps and the ability to cinch it down over your chest for stability. This leads to a stable carry, especially on uneven ground or if moving fast. I also like the massive, zipped mesh pockets on the shoulder straps – the best of any pack I tested. However, the back length only comes in one size and it can’t be adjusted, so if you’re taller or shorter than average then this may not suit.

If you’re looking for a pack that can do double duty, covering general backpacking with faster-paced adventures then this is worth a look – but I recommend trying it on first. The value is good.

Big Agnes Sweetwater UL 60L

Big Agnes Sweetwater UL 60L

Alex Roddie’s verdict

The harness isn’t supportive enough for heavy loads and a few design quirks make this harder to recommend.
Pros
  • highly water-resistant design
  • recycled materials
Cons
  • uncomfortable harness
  • unstable carry
  • too much cordage in design
  • no floating lid
  • no hipbelt pockets

Volume: 60 litres
Closure: zipped lid
Back: adjustable, ventilated, with internal injection-moulded frame
Hipbelt: cushioned, ventilated, adjustable, 5 inches
Pockets: 2 stretch mesh on harness, large lid pocket, large front stretch mesh pocket, 2 stretch mesh side pockets
Sizes: S / M / L
Women/Mens version: no
bigagnes.com

One of the biggest packs in this test, the Big Agnes Sweetwater UL 60L has a relatively minimal design with a running-inspired harness and large stretchy mesh pockets. However, the harness isn’t supportive enough for heavy loads and a few design quirks make this harder to recommend. Although the design is inspired by minimal, ultralight packs, it’s heavier than you might expect, and that’s partly thanks to the stiffened frame system. The harness is based on a running vest, with broad shoulder straps and double chest straps, but the shoulder straps are not as padded as I’d like and under extended use I found my shoulders getting sore.

On the plus side, the fabric is both recycled and has effective water-resistant coatings – I found it the most water-resistant pack tested (although it’s still not fully waterproof).

Key features of the best backpacking packs

Back System

This is designed to transfer weight from the shoulders to the hips. An adjustable system helps achieve a customised fit. Many are designed to allow airflow to help keep the back cool. 

Shoulder straps

Padded and contoured straps that prevent chafing are ideal for heavier loads. Adjustable straps with buckles on the top of the shoulders and under the arms help pull the rucksack closer to the body. A chest strap adds stability and should be height adjustable to suit different body shapes.

Hip belt

This carries most of the load and should be padded and easy to adjust. Pockets on the hip belt are perfect for small essentials.

Top pocket/lid

Covers the opening to the main compartment and typically contains one or more zipped pockets. The lid may be fixed, extendable, or floating, (meaning it can be removed entirely).

External pockets

Useful for storing items needed quickly, such as water bottles or spare layers. These may be on the side, or the main body of the rucksack.

Compression straps

Useful for securing external items like trekking poles or roll mats. Side straps are helpful for compressing the bag when partially full.

Rain cover

An adjustable cover that attaches to the outside of the bag to provide some protection from the elements. Rain covers are not fully waterproof and often come loose in high winds.

Volume

A 50-litre pack works well for shorter trips with lightweight gear, but a larger volume may be better suited to extended trips or bulkier equipment.

Materials

Polyester and nylon are lightweight and strong. Look for ripstop and high denier fabrics for durability. Recycled polyester is preferable if the rucksack lasts, but it’s not easily recycled again. Of course, even the best backpacking packs do need some TLC, especially after heavy use. Find out how to clean your backpack and how to re-proof your backpack so they’ll last as long in the hills as you.

Fit

Fit is critical, so check brand size guides and measure yourself. Try the loaded pack on and adjust the straps. It should feel stable, with the centre of gravity near the hips and no gaps at the shoulders.

How to fit a backpack

Once you’ll be carrying gear for camping larger packs are needed and the fit becomes important. A properly fitted and adjusted pack should mean most of the weight is carried on your hips not your shoulders. To do this the back length must be correct. Too short and the hipbelt will ride too high and won’t support much weight without cutting painfully into your stomach. Too long and the top of the shoulder straps will be above your shoulders, making the pack unstable, or the hipbelt too low to fasten tightly. In either case the pack will be uncomfortable to carry.

To find the right fit packs should be tried on fully loaded. It’s worth taking time to do this. A comfortable pack makes a huge difference to the enjoyment of a backpacking trip. Most packs come with specific fitting instructions and it’s always worth following these.

These are the basics:

  • The key for the correct fit is the length of your back, measured from the base of the neck to the upper hipbone (technically from the seventh cervical vertebra to the top of the iliac crest). Having someone measure your back length with a flexible tape measure is the best way to find this. Your actual height is not important – some people have long legs and short backs, other have short legs and long backs.
  • Packs generally come in 5 centimetre/2-inch increments. If you’re on the edge of two sizes it’s best to try both on to see which feels best.
  • The padded section of the shoulder straps should curve under your arms leaving only a relatively short length of webbing for adjustment. How far apart the shoulder straps are at the top matters. Too wide and the straps can feel as though they’re falling off. Some packs have shoulder straps that can be adjusted for width. Women’s packs generally have shoulder straps that are closer together at the top than men’s packs.
  • If the back length is right the hipbelt should wrap round your hips with the upper edge about 2.54 centimetres/1 inch above your hipbones so that the weight is carried comfortably on your hips.
  • The padded sections of the belt should come round the side of your hips to help spread the load. Some packs have hipbelts that allow you to adjust the length of the padded sections. Many hipbelts are shaped so they curve over your hips.
  • Most packs have narrow straps that rise from the upper shoulder straps to the top of the pack back. These load lifter or top tension straps are designed to pull the load in over your shoulders to increase stability and to lift the shoulder straps off the top of the shoulders and transfer the weight to the collarbones. Loosening and tightening these straps while walking can adjust the weight between the hipbelt and the shoulder straps. To be effective load lifter straps should rise at an angle of around 45 degrees.
  • The final item to adjust is the sternum strap that runs across the top of the chest. This pulls the shoulder straps inwards and increases stability. Sternum straps can be moved up and down the shoulder straps. To be effective and comfortable they should sit high up, just below your neck. They’re not essential but can be very useful when scrambling or hiking on rough terrain.

Learn more about how to choose a backpack from Equipment Editor Chris Townsend. Only when you have a pack that fits your back should the features of the pack be considered. It doesn’t matter what pockets, compartments, straps or other features a pack has if it doesn’t fit.
