The wind on your back. Sirrus 24 brings true innovation and quality to the ventilated pack world.

Inspired by Osprey's AntiGravity™ technology, Sirrus 24 provides a fully adjustable AirSpeed™ ventilated back system which combines the 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. Sirrus' backsystem also offers an impressive women's specific fit, with an ergonomically shaped hipbelt, harness, yoke and backpanel.

The classic styling and clean design, alongside an impressively comfortable carry makes the Sirrus 24 a firm favourite for walkers and hikers who are looking for a ventilated daypack with enough capacity for spare clothing, food, water and equipment. The detachable raincover stored in the bottom pocket increases weather resistance and tough nylon fabrics ensure durability. Sirrus 24 features a large panel opening, an easy access pocket on the top and a large, vertically zipped expansion pocket on the front which is perfect for securely storing a jacket or spare layer for easy access. Sirrus 24 is the perfect pack for warm days on winding trails.

Sirrus 24 is compatible with all Hydraulics™ and Hydraulics LT™ reservoirs.
