Best Mountaineering Backpack of 2024

Reasons to Buy

• Superior durability
• Very comfortable
• Versatile - even useful as a summer backpack
• Great value

Reasons to Avoid

• Top lid is the only spot for your small, loose items
• Not the lightest mountaineering backpack

The Osprey Mutant 38 is a solid, very durable mountaineering backpack that has all the right features and is one of the most comfortable backpacks we tested.

The comfort really is the highlight of this backpack. It has just right amount of padding and feels like it's a part of your body when the hip belt is tightened up. The narrow profile means there isn't a lot of bulk to get in your way, so you still feel reasonably nimble, even with a fully loaded backpack of mountaineering equipment.

The removable top lid is nice, we definitely appreciated that for slimming the bag down for summit pushes. The one caveat here though is that the top lid is really the only spot you have to throw all your small, loose items in to. There's no other small pockets to stash anything in. If you foresee yourself removing the top lid, it's good to bring along a mesh bag that you can throw small items in to, otherwise they will just get lost in the main compartment.

The helmet holder is a nice touch. You can use it either on the top of the bag or the front. It does a great job of holding your helmet, and it's easy to stash when you're not using it.

The various straps and attachment points are all quite good. The ice axe holders are well designed, though we did have one case of an ice axe mysteriously becoming detached, so something to be a little bit wary of. The side compression straps are great for carrying skis. They seem very solidly built, and unlikely to rip or break from a pair of skis with boots attached being shoved in. They're a little small for holding gear, but you can get a few slimmer things in there without too much effort.

We added some bungee cord to the front two daisy chain attachment thingys. This seemed like a solid improvement, especially for carrying light but bulky items (foam sleeping pad). This would be nice to have from Osprey but it's easy enough to add yourself, and we only really found it necessary when using this bag for carrying overnight gear, which is a little bit outside of it's intended use anyway.

Speaking of overnight gear, this mountaineering backpack has also become a low-key favorite of ours for minimalist backpacking trips. You can't pack a ton of stuff with only 38 liters, and the build quality and weight is a little bit overkill for a more relaxed summer backpacking trip, but this really is a comfy backpack and we found ourselves reaching for it for quick overnight trips.

It's not the lightest pack. With mountaineering packs there is a bit of a trade-off between durability and weight, and the Osprey Mutant 38 definitely trends more towards durability. You won't find any futuristic fabrics here, this is a classic durable nylon backpack, and it's got the weight to prove it. But we've noticed no real wear or tear from all our use, so any extra weight really went in to making this thing bomb-proof, which we like.

The value is also great. With a straight-forward design and no trendy fabrics, it's easy to keep costs down, and Osprey have done a solid job of doing just that.

Reasons to Buy

• Very lightweight
• Optimised for mountaineering
• Solid comfort

Reasons to Avoid

• Not suitable for related activites, like ski mountaineering
• Lack of peripheral pockets

Arc'teryx is no stranger to the outdoor gears world, and the Alpha FL 40 is a testament to their expertise. This mountaineering backpack is full of features that climbers will find pretty handy.

This 40 liters capacity pack is thoughtfully designed with only one large, zipper-less compartment. It lets you stuff in your gear quickly and efficiently while on the move, minus any fiddling with multiple zippers. Handy for when you are on an incline and don't want to spend ages unpacking and repacking.

Made from N400r-AC^2 nylon 6 ripstop material, it brags about its durability. A fair chunk of online reviewers spoke highly of how well the bag held up under tough conditions, tackling everything that harsh weather and rough terrains threw at them.

The Alpha FL 40 wins brownie points for weighting just over a kilogram. This light-weight feature was extensively praised by backpackers, allowing them to move quicker and with less strain.

It's praised for its top-tier waterproofing capabilities, potentially making the rain cover redundant. While a few customers grumbled about the lack of a built-in rain cover, most reviews highlighted the advantage of not having to wrestle with adding on an additional coverage in the middle of a downpour.

The pack comes with a simple roll-top closure, something that most customers found convenient. A few reviews, however, indicated that the adjustment period could be frustrating for folks who are used to traditional closure methods.

Lack of external pockets didn't quite go down well with some customers. They found it inconvenient to dig through their pack for smaller items needed in a hurry. While others mentioned its paired-down design as an advantage, stating less frills made for quicker movements.

The bag also features fully removable straps for carrying ropes, ice tools or even skis; a great addition for climbers of various disciplines. This was celebrated in several reviews, particularly for the customization option it offered to users.

The competitors may offer more extensive padding, but Arc'teryx Alpha FL 40 opts for something more streamlined. A few customer reviews expressed discomfort after prolonged usage, given the minimalistic padding. On the flip side, the vast majority were full of praises for the shoulder and hip straps that offered good load distribution.

On the price front, this bag falls on the higher end of the spectrum, leading to some grumbles about it being not value for money. However, many reviews highlighted that the high price tag is justified by the backpack's performance, durability, and trend-setting design.

Reasons to Buy

• Versatile
• Ample gear loops and lash points
• Decently lightweight

Reasons to Avoid

• We're not crazy about the strap system

For seekers of a sturdy and practical backpack that'll keep up with your mountaineering adventures, the Black Diamond Speed 40 seems to tick the right boxes. The brainchild of a trusted brand, this bag brings a raft of features to the table that many seasoned adventurers have come to appreciate.

Several online reviews from customers who've used this product give it high marks for its durable, water-resistant fabric that can withstand harsh weather conditions. The Speed 40's compact, sturdy build brings reassurance to mountaineers that their gear will be protected.

In addition to its durability, buyers have praised the design of the Speed 40, which happens to be relatively streamlined for this type of backpack. Its aesthetics aren't just for show; the slim design enhances the backpack's practical features. For example, a removable top helps convert it to a lighter, smaller bag, proving helpful on less demanding excursions.

One key feature appreciated by users is the reACTIV suspension system. This innovative feature enables better weight distribution, making the bag feel much lighter than its actual weight. It does wonders when it comes to comfort, allowing mountaineers to traverse treacherous terrain with relative ease.

Despite all the positives, some customers have pointed out a few cons to owning the Speed 40. Some users have criticized the lack of external pockets, most notably the absence of a hip belt pocket. Such a pocket could have provided easy access to necessities like a compass or snacks. Another drawback is that some customers have issues with the size options, finding them either too big, or too small.

Lastly, as per the online reviews, those who frequently hike at night expressed their wish for more reflective patches on the bag for safety reasons. The Speed 40’s dark color and lack of additional reflectivity can make visibility a bit of a challenge in low light.

Reasons to Buy

• Great value for money
• Durable and sturdy design
• Excellent weather resistance
• Impressive accessibility and gear organization

Reasons to Avoid

• Could improve in carrying comfort
• Size may not be suitable for everyone
• Crampon attachment needs refining

If you're on a budget, the Mountain Hardwear Scrambler 35 is one worth considering. This backpack is a reliable choice when you're hoofing it up the hill or trekking cross-country, brimming with features that get a bigger bang for your buck.

What's got the buyers' attention? The pack's robust and water-resistant finish. The scrappy 420D nylon build can withstand challenging terrain without fraying at the seams, a bonus for any avid camper. Sure, it may not be entirely impermeable, but the rainproof HardWave suspension contours to the curve of your back to deflect water away, keeping your gear dry during those sudden cloudbursts.

Reviewers often rave about the versatile storage. With its roomy 35 litres capacity, they find it's sufficient for a full day's hike, scrambling, or even a lightweight overnight trip. The main compartment zips open and shut a breeze, while the side pockets are perfect for carabiner-clipped water bottles or energy snack bars.

People also love the forward access zip that allows you to conveniently grab essentials without digging through the whole bag. Very handy, indeed! Another add-on is the top carry handle, a simple feature but surprisingly notable in customer reviews.

However, it's not all sunshine and rainbows. A lot of feedback indicates that the hip belt isn't generously padded, which could make for an uncomfortable carry on prolonged climbs, especially with heavy loads. Also, the lack of a sternum strap has struck a sour chord with some customers, citing stability issues when the pack is full to the brim.

Also worth mentioning is that some buyers voiced frustration about their hydration bladder not fitting within the dedicated sleeve. It seems this feature falls short and might affect users who rely heavily on hydration during treks.

So there you have it. The Mountain Hardwear Scrambler 35 backpack might be a humble hero on a tight budget. With its rugged durability and smart design, there's a lot to admire. But do bear in mind its less shining aspects, like the insufficient hip padding and the hit-and-miss bladder sleeve. Because hey, as much as we love a bargain, you want your purchase to hit the mark for what you need in your mountain escapades.

Comfort is king with this backpack. The padded shoulder straps and hip belt were a standout feature among users, the design allows for body-hugging comfort without compromising on breathability. Customers were quick to note that the pack rode comfortably on their hips and didn’t lead to unnecessary sore spots or discomfort after long periods of wear.

Overall, the consensus among users was that while the Hyperlite Mountain Gear Prism carries a heftier price tag than some of its rivals, it provides a good return on investment.

The Mountain Hardwear AMG 75 is designed for the wanderer and adventurer in you. It's a pack that can keep up with the most treacherous terrains and extreme conditions, highlighting its durability and robust build. It's perfect for those lengthy expeditions that require you to carry more, thanks to its whopping 75-liter capacity.

It doesn't compromise in terms of comfort. Its HardWave framesheet conforms precisely to your back, distributing the hefty load evenly, preventing any sagging and offering that much-needed support. The padding on the shoulders and the hips are very comfortable, letting you lug around your equipment without punishing your back.

Some of the users appreciated the pack's mobility despite its large size. The pack has a multi-access system for the main compartment, which simplifies reaching your gear no matter where it is packed. It also features ample pockets, including a removable top pocket that doubles as a hip pack for short side excursions.

The dual-density foam hip belt is a favorite feature among many reviewers as it provides excellent load distribution and comfort over several hours. However, some users have mentioned that it takes a bit of a trial to adjust it properly for optimal fit, and those with a thinner frame may find it a bit bulky.

Its durability is a highlighted selling point from several customers. Its HardWave frame coupled with its resilient 840D HT ballistic nylon can withstand harsh weathers and challenging terrains. However, this doesn't mean that the bag is immune to wear and tear. A few reviewers recorded some minor cosmetic issues after prolonged use.

Lastly, it's worth mentioning that the Mountain Hardwear AMG 75 is a bit on the heavy side, and some might find it cumbersome if their expeditions involve a lot of high-altitude climbing. But considering its capacity, durability, and comfort, many believe it's a worthwhile tradeoff.

Reasons to Buy

• Top-notch comfort levels
• Superior gear organization
• Robust durability and weather resistance

The Ortovox Peak Light 40 has established itself as a premium option in the Ski Mountaineering niche. It's designed with focus on reduced weight, but doesn't compromise on comfort or durability. As its name indicates, it weighs extremely light at around 40 ounces which makes it a perfect companion for long, arduous climbs.

Made using high-grade nylon, the bag may initially impress you as delicate, but you'd be surprised by its strength and reliability. Throughout various climbs, people who have used it highly appreciated the material's resilient quality that kept it safe from sharp rocks and ice.

A distinct feature that won the hearts of many users is its 3D foam back system, which distributes the weight evenly and provides a good deal of comfort while carrying heavy loads. Its smart design and numerous, practical pockets make it easy to access climbing equipment quickly.

One feature that some users commented upon was the robust ice axe and ski fastening straps, which are ideal for maintaining a streamlined pack design when traveling. Another plus point is the 'circumferential zipper', which permits a quick and simple access to buried items in the main compartment without messy rummaging.

Yet, it's not all roses. Some customers found the 40L capacity limiting. They found it hard to fit in all their gear for multi-day ski tours. Others felt the waist belt an unnecessary addition, as it couldn't get any thinner and took up room without adding much practical value.

Lastly, let's not forget the hydration system compatibility. Buyers appreciated that it includes an outlet for a hydration system, but have flagged that the system itself is sold separately.

In summary, the Ortovox Peak Light 40 is a well-reviewed backpack praised for its lightness, durability and clever design. Despite a few suggestions for improvement, it's deemed a solid choice for ski mountaineers.
