Backpacks and Rucksacks
Our backpacks and rucksacks are sized in litres, so start with how long you'll be out. Gnarl 15L is a light daypack for fast hill days, and Ledge 35L carries extra layers for big days and winter. Orion 45L is a mountain rucksack for winter and alpine kit, and Pacific Crest 55L and 65L are for multi-day backpacking. Gourdon is a waterproof roll-top pack in 20L, 25L and 30L. For running and riding, there are the Arrowhead 6L and Artlu 10L vests, Idris 25L for ultras and Skytrail 14L for mountain biking.
Backpacks and Rucksacks
Size a pack by how long you'll be out and what you carry. A summer hill day fits in 15 to 25 litres. Winter layers, a stove and a flask push you towards 35 litres or more, and a multi-day trip with a tent and sleeping bag needs 55 litres or more. Fit matters as much as size: see choosing the right backpack size and how a backpack should fit.
Running Packs & Hydration Vests
A running vest sits close to your body so it doesn't bounce, with drinks at the front where you can reach them on the move. For shorter runs and rides, the Vora 6 waist pack keeps essentials to hand. Artlu and Vora both work with our Bota hydration bladder.
Waterproof Backpacks
A roll-top closure and waterproof fabric keep everything inside dry without a pack cover, which suits cycling, kayaking and hillwalking in sustained rain. Gourdon comes in 20L, 25L and 30L.
Climbing & Technical Packs
Our climbing packs are designed for the specific demands of technical objectives: ice axe loops, helmet carry, gear organisation and a profile that doesn't catch on rock. The Gnarl 15 is a proven crag pack. The Presta 25 works for longer days with more gear.

Designed by us, direct to you
Three principles guide every pack we design: keep the weight down, leave you free to move, and carry the load comfortably and steadily, so it stays put on rough ground.
Our gear goes directly from us to you. We design our packs here in the UK, and our warehouse team sends them straight to your door, or you can buy them in one of our stores. There are no distributors or retailers in the chain. It's how we keep making high-performing packs at the best possible value.
