Mountain Warehouse Cargo Bag Review: Cheap, Huge, and Surprisingly Useful

By Editorial Team | April 2026

The Mountain Warehouse Cargo Bag is the right kind of simple. It gives you 90 litres of carry space, backpack straps, and duffel handles for £49.99, which makes it a strong choice if you want one bag for weekends, sports kit, or camping gear. The appeal is straightforward: it solves awkward packing without asking you to buy proper luggage.

Our pick: Mountain Warehouse Cargo Bag

Mountain Warehouse Cargo Bag — £49.99

This is the best pick if you want a big soft bag that can switch between backpack, duffel, and hand-carry modes without getting fussy. Our score for it is 7.4/10, and that feels fair: it does the core job well, then stops before pretending to be a suitcase.

Why it works:

• The 90-litre capacity is genuinely useful for long weekends or bulky kit, not just marketing fluff.
• Padded, adjustable shoulder straps make it bearable when you have to carry it for more than a few minutes.
• The internal zipped mesh pocket gives you one sensible place for chargers, wash kit, keys, or small valuables.

The honest trade-off: this is soft luggage, not structured travel kit, so if you want wheels, rigid organisation, or proper heavy-rain protection, this is the wrong bag.

Buy the Mountain Warehouse Cargo Bag here if you want a single carry-all that covers travel, sport, and outdoor gear without spending much.

Best upgrade: Patagonia Black Hole Duffel 70L

Patagonia Black Hole Duffel 70L — around £160-£200

This is the upgrade if you travel often and want a tougher, more confidence-inspiring bag. It is the duffel people keep recommending for a reason: the material, carry comfort, and overall build are better, and it makes more sense if your bag lives in airports, boot rooms, and overhead bins instead of just the occasional weekend away.

Worth it if: you want a premium duffel that will take regular abuse and you are happy paying extra for better materials and longevity.

Best budget pick: Osprey Daylite Duffel 60

Osprey Daylite Duffel 60 — around £60-£80

This gets you into the same backpack-duffel idea for less money, but with less space. It is the better low-cost pick if you do not need 90 litres and want something lighter and easier to live with for gym runs, short trips, or everyday kit hauling.

Worth it if: you want a cheaper, smaller alternative and do not need the Mountain Warehouse bag’s full volume.

How we chose

We looked at what actually matters for this type of bag: capacity, carry comfort, weather resistance, and whether the layout is practical rather than clever for its own sake. We also checked current duffel-bag recommendations from GearJunkie, Wirecutter, and Outdoor Gear Lab to make sure the upgrade and budget picks are real, available alternatives with sensible price positioning.

Frequently asked questions

Is a cargo bag better than a suitcase for short trips? Yes, if you need flexibility more than structure. A soft bag is easier to cram into cars, carry over rough ground, and use for mixed gear, but it is worse for neat packing.

Is £49.99 a good price for this bag? Yes. For 90 litres plus backpack straps and a waterproof fabric finish, it is competitive and cheaper than the well-known premium duffels.

Will it keep my stuff dry in heavy rain? No — the fabric is for light rain and splashes, not full waterproof protection.
