Inspired by Osprey’s AntiGravity™ technology, Stratos & Sirrus provide a fully adjustable AirSpeed™ ventilated back system which combines single piece construction of the backpanel and hipbelt with highly breathable suspended mesh.

This allows for increased comfort in warm weather, even with a heavy load. The Sirrus backsystem offers impressive women’s specific fit, with an ergonomically shaped backpanel, hipbelt, harness and yoke.

The classic styling and clean design, alongside an impressively comfortable carry makes the Stratos & Sirrus a firm favourite for walkers and hikers. The detachable raincover stored in the bottom pocket increases weather resistance and tough nylon fabrics ensure durability. Stratos & Sirrus are the perfect packs for long, warm days on winding trails.
