Ready to put in the big miles? Osprey’s bestselling Atmos AG pack is a tried-and-tested back-country companion – and the 50-litre capacity is bang-on for long-distance trips where you’re not going to go too long between resupplies. It’s got plenty of storage for camping and mountaineering gear, but a big part of what keeps the Atmos in the ‘top multi-day backpack’ lists is the superb carrying comfort. It features Osprey’s body-hugging AntiGravity suspension system, with a continuous back panel of lightweight, highly ventilated mesh. The torso length is easy to adjust, and grippy silicone print on the lumbar panel helps the pack sit securely in the right place. And for anyone planning an extended trip, the hip belt can be cinched in and fine-tuned on the fly – in case you find your waist shrinking as you eat up more miles than calories.

The Osprey story started in California in the 1970s, with one man, a sewing machine and a vision to make the world’s best outdoor packs. Today, it’s one of the most recognisable rucksack brands.
All of Osprey's packs share the same twin hallmarks of fit and comfort. In fact, Osprey was an early adopter of breathable mesh, ergonomic hip-belts and packs designed specifically to fit women. Breathable back panels are still a feature of all their packs, and all except their most lightweight bags come with adjustable back-lengths for a perfect fit.
And in a world where outdoor enthusiasts are increasingly conscious of our environmental impact, many Osprey packs are made from durable recycled fabrics, while all feature PFC-free water-repellent coatings.
