In this article, we’ve compiled the results of our staff’s in-depth testing for the latest and greatest multi-day hiking backpacks. Dozens of backpacking packs have been tested and we’ve narrowed them all down into a list of our top performers.
What to look for when choosing a pack? Backpacking packs for hiking come in a variety of sizes. The size that’s best for you depends on the trips you intend on undertaking. If you’re trekking between huts or hostels, especially in warmer weather, a 35-litre backpack should be adequate. Ultralight backpackers – the types of people who chop off half their toothbrush – will also stick to around 35 or 40L for longer trips with a tarp or tent outer.
For those who like backpacking with a bit more comfort at night, or in colder months when you need a heftier sleeping bag and sleeping mat, something between 40 and 55 litres should be right. Backpacks over 55L should suit anyone heading into areas of wilderness for long periods of time, when there’s little chance of resupplying and you have to carry everything you need in with you.

Once you’ve decided on the size, the next consideration, and the one that you should prioritise above all else, is the carry comfort. The backpack is going to essentially be your home for a few days; it’s going to get heavy, it’s going to get annoying, and it must be comfortable. And the only way to test that is to try it on. Fortunately, here at Outdoors Magic, we’ve tested a whole bunch of backpacking backpacks so you don’t have to.
While this list covers men’s and women’s options, if you’re looking for women’s hiking backpacks specifically, we’ve done some tests for that too. Check out our results in our best hiking backpacks for women round up. Elsewhere on our site, you’ll find similar tests we’ve conducted to find the best daypacks for hiking, and the best duffel bags too.

1. Osprey Kestrel LT 45L Backpack
Our men’s winner: the best backpack overall following our tests
Osprey Kestrel/ Kyte LT 45L
★★★★½
Price: £165
Weight: 1.83kg
Best for: wild camping, hut to hut trekking, multi-day hikes
Pros: durable, comfortable, loads of useful details, ergonomic, sustainably made materials
Cons: only one size option, though back system is adjustable
New for 2026, we’ve been out testing Osprey’s LT (‘lightweight’) Kestrel backpack in the Lake District recently. The backpack features the same dependable performance as the original Kestrel/ Kyte series, but with a more streamlined and lightweight design.
Specifically, the materials that are used in the LT backpacks are lighter, the internal frame is more streamlined, and features such as external strapping and gear lashing points have been stripped back slightly for faster and lighter adventures.

Both versions of the Kestrel/ Kyte still have Osprey’s iconic AirScape back panel, torso-length adjustability, built-in raincovers, side-zip access, and impressive internal organisation. What’s different now is that you have two great options instead of one to choose from, depending on what your hiking trip looks like.
Our tester James Forrest recently used the LT Kestrel along the Wordsworth Way. He said: “If you want a pack that is fully-featured and durable with a high-tech back system, the Kestrel is a sensible choice. It’s a gear-hauler that works well for overnighters.”
As we’ve come to expect from Osprey, there are loads of useful details, including ice axe/ trekking pole loops, a front shove-it pocket (we found this was perfect for a down jacket) and side access to the main compartment. Credit to Osprey for using bluesign approved 100% recycled fabrics here too.
Full Specifications
Made from bluesign approved, 100% recycled tough nylon / available in men’s (Kestrel) and women’s (Kyte) versions / various capacities within the range / rain cover at base / top-loading main compartment with cinch closure / internal hydration bladder sleeve / trekking pole and ice axe loops / stretchy and roomy side pockets / stretchy shove-it panel on front / padded hipbelt with pockets / side-zip secondary access / zippered pocket on top lid and under lid / 45L dimensions: 68H X 34W X 30D CM.

2. Fjällräven Kajka X-Lätt 45L
Our women’s winner: the best backpack overall following our tests
Fjällräven Kajka X-Lätt 45L
★★★★½
Price: £295
Weight: 1.185kg
Best for: backpacking, trekking, hut to hut hiking, wild camping
Pros: durable and built-to-last, very stable under big loads, modular design, great distribution of weight, good water resistance, solid breathability in cool to mild weather
Cons: not for hikers who prefer ultra- minimalist packs, no zips on hipbelt pockets, not as breathable as fully suspended back system, starts to feel heavy at 11.5kg+ loads (the recommended limit is 13kg mind you)
The Kajka X-Lätt 45L marks Fjällräven’s move into the lightweight backpack market for 2026. Taking inspiration from the brand’s much-loved Kajka trekking pack, this pared-back version offers a more streamlined, modular design while keeping the distinctive aesthetic and iconic birch wood frame that the range is known for. The weight saving is significant, too: while the original Kajka 35L tips the scales at 2150g, the X-Lätt 45L comes in at just 1185g.
OM tester Jazz has put the Kajka X-Lätt through its paces over summer and autumn this year, including on a multi-day hut-to-hut trek along the Grand Tour des Combins in the Swiss Alps. Despite carrying a fairly substantial load, she was impressed by how well the pack performed. She said: “This is the kind of backpack that oozes quality which is reassuring considering its price. I packed it quite heavily (approximately 11kg) for some trekking in the Swiss Alps and was really impressed with how stable it felt, especially across big mileage days with a variety of different terrain types (rocky alpine sections, boggy and rooty forest paths, boulder fields, hard-packed dirt, loose scree etc.).”

Alongside its impressive carrying comfort, Jazz was particularly taken with the durability of the materials and the flexibility offered by the modular design. She explained: “If you prefer a completely minimalist set-up, you might find the modularity a bit of a faff. I personally loved it. I think it gives the pack added versatility as you can fine tune it to the specialities of each hiking trip you go on, and what each trip requires.”
Striking the right balance between low weight, durability and reliable carrying comfort is no easy task, but we think Fjällräven has made a very convincing case with the Kajka X-Lätt 45L. It’s a substantial investment, but one that should reward regular use over many years. While it won’t necessarily appeal to those chasing the absolute lightest possible setup, its combination of a robust construction, versatile modularity and reduced weight makes it a very compelling option for trekkers who want the best of both worlds.
Full Specifications
Two sizes: S/M (1160g) and M/L (1185g) / longer straps and slightly longer and wider hipbelt in the M/L / dimensions: 63cm (H) × 30cm (W) × 28cm (D) / carry systemm: FSC-certified birchwood frame / main body fabric: Vinylon F (100% vinylal) / reinforcements, straps, base, back panel, hipbelt: recycled 330D polyamiderepairable / unisex / detachable hipbelt / detachable chest strap / 8 pockets / fixed top lid / snow lock closure and top opening / detachable zippered inner pocket converts to cross-body bag / external stretch pockets / removable front pocket sleeve / hydration system compatible / side compression straps.
3. Ortlieb Atrack 35L Backpack
Selected as our choice for best waterproof backpack
Ortlieb Atrack 35L
★★★★½
Price: £220
Weight: 1560g
Best for: Hiking in wet weather, canoe/kayak adventures
Pros: fully waterproof, durable, very versatile
Cons: doesn’t have all the extra organisation pockets of a non-waterproof bag
The Ortlieb Atrack 35L is a fully waterproof backpack ideally suited towards activities where you’re planning on taking a soaking, whether that be in rivers, lakes, oceans or just on hilltops. This is a pack that trekkers, bikepackers, ski-tourers, kayakers and packrafters can all genuinely rally behind.

A long waterproof zip is located on the back of the pack opens the bag up like a duffel bag, allowing you to get a look inside before picking out what’s needed. Internally, there are four zippered pockets on the Atrack while on the outside there are two net pockets perfectly suited for water bottle storage.

Our tester Ieuan Barrett said, “I’ve not tried it out with a massively heavy weight just yet but I’ve used it for a load of around 10kg containing my camera equipment, wet weather gear and lunch etc., and it coped well. The bag is very comfortable too, with the padding and structure at the back adding support whilst walking. The chest strap also aids in taking strain off the shoulders.”
During our tests, the durability of this thing really stood out – it feels extremely hardwearing. The carry comfort was good and the pack provided its promised wet weather performance. It’s a little fiddly in places and the main zip is quite stiff due to its waterproof design, but generally this is a pack that’s innovative and that comes across as being very well made and built for the outdoors.
Full Specifications
Tear resistant nylon fabric / 4 zippered inside pockets / adjustable back panel / ergonomic shoulder straps / two outside net pockets / daisy chains on the front / 4 compression belts

4. Gregory Maven 58L Backpack
Best Backpack for Big Loads
Gregory Maven 58L
★★★★½
Price: from £225
Weight: 1.59kg
Best for: multi-day backpacking, long-distance outdoor adventures
Pros: heaps of storage compartments, luxurious hipbelt, very comfy back system
Cons: won’t suit ultralight hikers as much
Here at Outdoors Magic, we’ve been trying and testing Gregory packs for many years now. Previous models like the Alpinisto and Focal have impressed us, and this one hasn’t let us down either. While not geared towards ultralight hikers, in our experience, it feels light compared to other packs of this size on the market, and should suit most multi-day adventurers very well.
Our most recent gear tests have taken us to North Wales, in and around the Rhinogydd mountains to be precise, where we’ve been putting the Gregory Maven 58 through its paces. Specifically designed for women (the men’s equivalent is the Paragon), there’s a lot to like here, including an ergonomically designed hipbelt, an impressive AirCushion back panel, and heaps of innovative storage compartments for all your gear-hoarding needs.
