Welcome to T3's guide to the best hiking backpacks for the modern adventurer.  Once upon a time, the best hiking backpacks were great big, robust things, made from canvas and steel, with helpful leather straps for affixing muskets and machetes.Thankfully, today's best hiking backpacks are very different. They weigh in at a fraction of those old beasts, and without sacrificing any of that durability (in fact, they'll probably last longer).Don't let choosing your rucksack be an afterthought. While you might be focusing on picking up the best backpacking tent for your trip, or making sure you've got the best hiking boots for the terrain you're tackling, if your rucksack is wrong, it can ruin an otherwise meticulously planned expedition.  

The key trick is not to fall into the trap of taking the kitchen sink along with you for a day hike in the New Forest – light is right, and smaller rucksacks tend to be lighter than big ones. That said, planning ahead is also important. It's better to have a top-quality rucksack that suits you all year round, rather than four cheap ones in slightly different sizes and levels of discomfort, clogging up your cupboard. 

Finally, and really most importantly, make sure whatever pack your choose is adjusted correctly to your body shape before you set off – here's exactly how to fit a backpack properly, for the avoidance of doubt. For more guidance on materials and what to look for, head to the bottom of this guide. Or if not, read on for our pick of the best hiking backpacks 2021.

What's the best size for a hiking backpack?

One of the key things you need to establish before you buy is the capacity you're looking for, which is dictated mainly by how long you're travelling for. Roughly, this is the size of backpack to look for:

Single day hikes: 20L-35L

Overnight stays: 30-50L

Long backpacking expeditions: 50L+

Where you opt for the top or bottom end of the scale will depend on things like how light of a packer you are, the time of year you're travelling at and what activities you're doing.

1. Osprey Tempest Pro / Talon Pro

The best hiking backpack for big days out

Specifications
Capacity: 28L (Tempest Pro), 30L (Talon Pro)
Waterproof: Water resistant
Weight: 1kg (Tempest Pro), 1.1kg (Talon Pro)
Reasons to buy
+Perfect daypack size+Mountain-ready extras+Comfortable straps
Reasons to avoid
-On the heavier side

For our money, the best hiking backpack right now is the Osprey Tempest Pro (for men) and Osprey Talon Pro (for women). This excellent backpack will give you all the storage you need for a big day out as well as features that you'll appreciate if you're hitting the mountains and fells. For big days out you'll find hydration pack compatibility as well as loops for ice axes and trekking poles; these packs also feature well-designed strap systems that'll fit you snugly all day. The Tempest Pro gives you 28 litres of storage while the Talon Pro can hold up to 30 litres; enough for everything you might need for a long day's excursion. Bear in mind though that at around a kilogram in weight these might be a bit heavy if you're planning on keeping up the pace. They're water-resistant enough to withstand all but the heaviest downpour, and tough enough for most eventualities. In short either could easily become your favourite hiking companion.

2. Fjallraven Abisko Friluft 35

The best hiking backpack for weekends in the outdoors

Specifications
Capacity: 35L
Waterproof: No
Weight: 1.55kg
Reasons to buy
+Great quality+Well-placed pockets+Smart looks
Reasons to avoid
-Blue version shows dirt easily

A bit big for a daypack and not quite roomy enough for a week away, Fjallraven's Abisko Friluft 35 (available in men's and women's versions) is the perfect size for a two-day adventure in the outdoors. Its 35 litre capacity plus an extendable top lid mean that you can comfortably pack for two days way (or even three if you pack light), and it comes with plenty of additional pockets for stashing all your bits and bobs.

While it's not waterproof you can add some extra water resistance by treating the fabric with Fjallraven’s Greenland Wax, and it comes complete with a rain cover to protect it should you hit a downpour, while its waterproof bottom panel will help keep it dry on wet ground.

It looks great and it's comfortable to wear for extended periods, however we'd be wary of choosing the pale blue colourway as it attracts dirt like nobody's business. Go for the black or dark green instead and you'll be rewarded with a weekend pack that ticks all the boxes.

3. Arc'teryx Alpha AR 35

The best hiking backpack for mountain botherers

Specifications
Capacity: 35L
Waterproof: No
Weight: 1.17kg
Reasons to buy
+Super tough+Slimline design+Lots of attachment points
Reasons to avoid
-High end pricing

The Arc'teryx Alpha AR is a classic rucksack design, originally born out of the needs of dedicated climbers, but the result is an all-rounder in many respects. That climbing heritage gives you a very slim profile, just as useful on the North face of the Petit Dru as the District line, as well as loads of attachment points. These might seem unnecessary for everyday life, but the axe loops are just as useful for holding hiking poles as they are for technical leashless ice tools. 

The main thing you're getting here is premium wear-resistance, which means this pack will last for decades. Arc'teryx have got all technical here, building the rucksack body from a 'liquid crystal polymer ripstop grid' incorporated in a 'high tenacity nylon fabric', which certainly sounds tough as nails. There's a removable top lid and back framesheet if you need to cut weight, as well as a superb strap/hip belt combo that are near-indestructible but comfortable on long days too. If you need a reliable daysack that'll last till you get too old and doddery to use it, this is a top choice.

4. Snow Peak Active Backpack Type 01

The best hiking backpack for touring

Specifications
Capacity: 43L
Waterproof:
Weight: 1.84kg
Reasons to buy
+Dual-storage space+Handy daisy chains+Water resistant material
Reasons to avoid
-Little on the heavier side

A more traditional hiking rucksack design, the Snow Peak Active Backpack Type 01 ONE boasts a decent 43 litre capacity, more than enough for multiple days on the trail, hut-to-hut excursions and short camping jaunts. The two separate areas of storage help keep the contents organised, one accessible from the top, one via a zipped rear section, and with an outer of water-resistant nylon it'll shrug off all but the heaviest downpours. 

The super-wide hip belt should soak up much of the load-carrying work, and also has zipped pockets for trail essentials – handy for a soft flask and snacks to keep you fuelled on the go. On the downside, this is a heavier bag than we'd like (just under 2kg for the bag alone), and the price point is on the high side. However, if you're looking for that traditional dual-storage area hiking rucksack in tasteful tactical black, this is well worth checking out. 

Best hiking backpack: Berghaus Alpine 45

5. Berghaus Alpine 45

The best hiking backpack on a budget

Specifications
Capacity: 50L
Waterproof: Yes
Weight: 955g
Reasons to buy
+Light+Super clean lines+Keen price point

The Berghaus Alpine 45 keeps things simple, as well as the costs down, making it a strong contender in our best hiking backpack ranking. With a 45 litre capacity you’ve plenty of space for any adventure, but not enough to be tempted into taking the kitchen sink along. Neat side compression straps keep the clean lines intact even when in use, with plenty of additional attachment points for poles, skis, tents and a reflective bungee for that extra layer you’ve just taken off. 

A simple roll-top enclosure will keep the worst of the weather at bay, and is easily managed wearing gloves, while the back support is removable if shaving those extra grams is a priority. Low-profile straps and a slim-line hip belt reduce faff to the minimum without reducing comfort, and there’s even a small zipped pocket for essentials too. In short, there's everything you need here for a great day out, and nothing you don't. Sounds good to us…

best hiking backpack: Berghaus Fast Hike 32

6. Berghaus Fast Hike 32

The best hiking backpack for lightweight everyday outdoor fun

Specifications
Capacity: 32L
Waterproof: No
Weight: 640g
Reasons to buy
+Marvellously light+Strippable for even more lightness+Simple design for all occasions
Reasons to avoid
-Not huge

First off the bat, let's be clear – the Berghaus Fast Hike 32 is no big load carrier. Wannabe Amundsens should avoid. However, almost everyone else should be interested, as this is a bit of a smasher – very, very light, but a decent size for most excursions. It's even strippable for extreme lightness, should an extra 100grams really make the difference (it probably won't, but nice to have the option). 

Essentially what Berghaus has done here is produce a rucksack with the high-end alpine features of an extreme sports rucksack, but at a sensible price point and without using kevlar or graphene, to save a few grams. In short, you could buy a more expensive bag, but it'll be no better for the job, and if you buy a cheaper one it'll weigh a ton – this is a bit of a sweet spot. 

A 32l capacity is plenty for summer rambles, more serious single-day hikes, and perfectly good for hut-to-hut adventures in the alps. You'll get your commute cycle kit in it too, and it's small enough not to cause a fuss around town, as well as fitting in an overhead locker if needs be. Obviously there's a hip belt, hydration sleeve, side bottle pockets and a soft flask front harness pocket to boot. And it's suitable for both men and women, too. In short, a hiking backpack that's ideal for almost all occasions.

Best hiking backpack: Mountain Warehouse Ventura rucksack 40 litres

7. Mountain Warehouse Ventura

The best budget hiking backpack

Specifications
Capacity: 40L
Waterproof: Comes with rain cover
Weight: 1.2kg
Reasons to buy
+Great value+Rain cover included+Airflow back and compression straps+Range of colours to choose from
Reasons to avoid
-There are better quality options

The Mountain Warehouse Ventura is our best hiking backpack for those on a tight budget. Let's say you've just come out of uni and you're looking to go travelling; the likelihood is that you're not going to have tons of cash to spare. Suitable for camping, travelling and festivals, this is a great value hiking backpack that will become your trusty sidekick whenever it’s time to explore the outdoors. It features an airflow back to keep things cool, a compartment for a hydration pack, and compression straps to ensure it remains comfortable as you stride. There's also a rain cover if the heavens happen to open mid-hike.

Best hiking backpack: Arc'teryx Bora 50

8. Arc'teryx Bora 50

This robust all-rounder won't let you down

Specifications
Capacity: 50L
Waterproof: Yes
Weight: 2.18kg
Reasons to buy
+Comfortable+Luxury of all mod cons+Hipbelt you could hang a car on
Reasons to avoid
-There are lighter options

The Arc'teryx Bora rucksack has seen a few iterations, and if you spend any time outside you’ll see a few go by. This is because it is comfortable to wear—that massive hip belt takes the strain of even big loads, and at 50 litres this multi-day bag can handle whatever you want to throw at it. Multiple lid pockets help keep stuff organised (daytime items and snacks on the outside, car keys and head torch on the inside, for example), as well as an easy -access full-length zip leave very little else to be desired. OK so the weight is a little chunky at 2.18kg, but it's nothing to get upset about. Ultimately, this close second in our best hiking backpacks buyer’s guide will last you years.

Best hiking backpack: Mammut Lithium Crest

9. Mammut Lithium Crest

A versatile design, and good value for money

Specifications
Capacity: 30L
Waterproof: No but comes with cover
Weight: 1.6kg
Reasons to buy
+Adjustable+Multiple attachments+Value for money

The Mammut Lithium Crest packs in all the features you could possibly want, as well as a few new ones, but without breaking your back or your wallet. Weighing in at a mere 1.7kg, the Lithium sports daisy chains, loops for a mat, three side and front pockets, and axe and pole attachments. It's also hydration system compatible and incorporates a raincover. The back length is easily adjustable, which is helpful if you’re wearing bulkier clothes in the winter, or if you’re sharing one heavy rucksack between a mixed party to make faster progress. There’s plenty of space here for days worth of stuff, and with a separately accessible bottom compartment you have a fighting chance of being able to find things easily.

Best hiking backpack: Berghaus Ridgeway rucksack 65+10 litres

10. Berghaus Ridgeway Rucksack

The best hiking backpack for organised packers

Specifications
Capacity: 65L+10
Waterproof: Comes with rain cover
Weight: 1.81kg
Reasons to buy
+Bottom zip for easy access+Sections for water bottles, maps etc.+Expandable side pockets

Berghaus is pretty reliable when it comes to outdoor gear and the Berghaus Ridgeway Rucksack doesn't disappoint. There’s plenty of space to store your items, plus compartments for water bottles, snacks and maps. You can expand the side pockets out to give yourself an additional 10L of capacity, while the adjustable BIOFIT back system helps to ensure the backpack is comfortable to wear, no matter your size or shape. If rain makes an unwelcome appearance, there’s also a foldaway cover that you can take out when required. 

The best hiking backpacks: what to look for

Hiking is all things to all people, so getting the right balance between weight, size and robustness is key, especially for something you’ll be wearing on your back for many days in total. Modern materials mean that ye olde steel frame rucksacks are broadly unnecessary, unless you're in training and want to carry the extra weight. Here are some things to look for when choosing the best hiking backpack for you:

Volume
Arguably the most important starting point. How much do you really need to carry? Summer rambling along the coast requires a different set of kit to winter wild camping, but don’t get carried away and buy a giant windsock of a thing that needs an SAS team to carry once filled.

Fit
Check and check again that the rucksack fits your back well. Most makes have different back sizes available, so try a few on with both a light load and a heavy one (most shops have weight bags for this). If there's a hip belt, this should rest on the top of your hip bones, and adjust to a comfortable tightness – this can transfer a lot of weight from your shoulders to your hips, so don't underestimate the importance of a well-fitting hip belt. And of course, none of this is any good if the straps aren't adjusted correctly: here's how to fit a backpack.

Comfort
Walk around and move naturally to see if anything rubs or feels weird. By all means try the super-techno suspended mesh solutions to getting a sweaty back, but rest assured after a long day with a heavy rucksack, your back will be sweaty, so don't prioritise them over a really good fit.

Weight
Lighter is nearly always better, and that often means the minimum of random bells and whistles, which all add weight. Don't be afraid to cut off straps and fastenings you know you'll never use.

Pockets and straps
Think about what you'll need to carry, and how accessible you'll need it to be. Streamlined designs might look smart, but when you're having to unpack the whole thing to access your torch in the middle of the evening, pockets start to look more appealing.

Which materials perform the best?

Modern hiking backpacks are made from whatever fabric you desire, from dyneema and kevlar to canvas and steel. Just remember there is usually a compromise somewhere in materials, but also that simple, tried and tested materials are unlikely to let you down, whereas that experimental new kevlar weave might delaminate in strong sunlight. 

Although DWR coatings are helpful to avoid fabric wetting out and adding weight, covers and special 'waterproof' closures tend to not work in actual outdoor weather, so are best ignored.

Remember, the real ultralight hiking backpacks on the market will wear out pretty fast, so it's probably wise to pick a slightly more robust model with durable materials. But, again, your planned use is the key to choosing the right blend of weight versus durability.
