I already used it for 5 intercontinental hiking trips! Review: Huge space, high quality, max comfort. - Wow... what can I say. Starting with it arriving 3 days earlier than advertised, this bag is... probably built by the same people as built Dr Who’s police box! Loads of space in the main compartment, with extra if you pack out the snow collar. Cavernous too pocket which adjusts so you can pack something (sleeping bag, tarp, roll mat etc) between the snow collar and the ‘lid’. The side pockets look like they’ll be useless if the main compartment is packed but they still function perfectly. All hardware is sturdy but light weight. The YKK zoos can be a bit stubborn but I expect that’s because it’s brand new. Not so much as it’s inconvenience you. Love the built in rain cover, ample size and quick deploying. It can be detached and if you were to leave it detached you’d have another fair sized pocket on the underside of the bag. As for comfort, it is lighter than expected when empty. I’ve filled it but have no scales, so not sure how heavy it is, but it doesn’t bulge like the Bergen I’ve replaced with this. The plate and two aluminium poles that comprise the internal frame appear to be removable via a zipped compartment inside the main compartment. The stitching appears solid and complete all around however it looks strained in some places where I’ve (over)filled a pocket or two. However I gave it a pretty good tug before I loaded the bag and the seams didn’t give at all. The material isn’t as thick as the DD Bergen, but feels strong and doesn’t look like it’s going to give without the aid of something properly sharp and pointy. Once loaded I adjusted the 8 way torso length adjusted and loosened the shoulder straps to put it on. It felt lovely around the waist, but seemed to be sagging at the back, which was not a pleasant feeling as it was tugging at my shoulders. Luckily I found two more strap adjusters and when I pulled those tight, the whole pack was shifted close against my back and the weight disappeared off my shoulders completely. So take the time to adjust everything properly and you’ll find an excellent and confortable heavyweight cavernous bag! As a guide I’m carrying:- 1 x Hammock 1 x Underquilt 1 x 3x3 tarp 1 x 4 season sleeping bag Tree huggers, whoopie slings, 30m spool of paracord, 4 x carabiners. 1 x steel cylinder style camping stove 1 x titanium bush box stove 1 x Coleman performance gas canisters 440g 1 x stacking cook set (pan, pot, accessories) T-shirts, shemagh, scrim scarf, 2 pair long johns, spare socks. Micro fibre travel towel. 2 x collapsible cups Assorted plastic pots/cutlery/coffee bags Fire kit Trowel Collapsible stool. Head torch. The only thing I can’t get in there is the spare gas canister, but I don’t really need it with the two multi fuel stoves! I think most experienced wild campers would probably agree the bag can hold more than is actually needed quite adequately! Definitely buy it! ## Features - 【Large Capacity】The dimension of this hiking backpack is 27.5 x 13 x 9.4 inches (80 x 33 x 24 cm), and the capacity is 80 liters.

My son is a skinny teenager, and I wonder if he can do up the hip belt very tighly. Could you tell me how short this hip belt can go, please?** A: I'd say if he's less than a 30inch waist it wouldn't be very tight with just a t-shirt on. **Q: I need a bag that I can strap an 18kg five person tent to. Will the straps on this hold up to the task?** A: Straps may hold but you might have a difficult time if you load this bag up fully. Padding is subpar as is weight strap adjustments. For reference, with 22kg I was quite uncomfortable. **Q: does this have the waterproof official infon on the bag? If not it is NOT **Waterproof**** A: It comes with a waterproof cover that folds away but even that on contact with sleeping bag etc seeps threw... I can imagine the first one made (sample) was top of the line waterproof but like everything Chinese ones they get the contract they cut corners even in the top part moisture seeps in not worth the price unless you use it once a year in summer in a drought **Q: free returns** A: Great ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality *by C***I on 16 November 2025* Comfortable, reliable and has enough space for plenty of material/clothes.

I will start off by saying this was very uncomfortable for long periods of time but then I was carrying a lot, maybe if you don’t plan on filling it to full capacity it would be fine. Weight wasn’t distributed very well, straps weren’t that comfortable. I found even though I have a long torso there was such a large gap between my back and the rucksack it made me walk hunched over to support it, despite me putting most heavy items at the base of the rucksack so that my hips would support the weight, I am 5”7 for reference and I wore the torso adjustment on the mid setting but didn’t find it made much difference to this issue. The waist strap was also far too big for me this is very important to note if you are considering buying this rucksack, for a size 8 female I was not able to tighten it enough around the waist for support, had it of tightened up more it may have been more comfortable. I do think for this reason it is probably built better for a man. The main aspect is that I could open the rucksack from the front all the way round and the bottom this made it SO! easy to unpack all of my packing cubes and fit everything in, I couldn’t have coped with a top opening bag only. The appearance is great I loved the simple look of it, not too bright or feminine just simplistic, also quite liked all the useful shortening straps. I would say it’s a very durable bag, it was subjected to a lot of manhandling and throwing about onto coaches trains airports and floors, nothing has broken yet. Good bag overall I would recommend for the price! If you are looking for something more luxury in terms of comfort then spend the extra money elsewhere :) ## Frequently Bought Together - MOUNTAINTOP Hiking Backpack 80L Waterproof Mountaineering Backpack Large Camping Trekking Rucksack Multifunctional Climbing with Rain Cover - General Medi Mini First Aid Kit, 92 Pieces Small First Aid Kit - Includes Emergency Foil Blanket, Scissors for Travel, Home, Office, Vehicle, Camping, Workplace & Outdoor (Red) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/54445687-mountaineering-backpack](https://www.desertcart.jp/products/54445687-mountaineering-backpack) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-04-22*
