Sirrus 26 brings true innovation and quality to the ventilated pack world. Inspired by Osprey's AntiGravity™ technology, Sirrus 26 provides 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. 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 26 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 26 features a double-clipped lid opening with draw-cord fastening, a large, easy access pocket in the lid and a vertically zipped expansion pocket on the front which is perfect for securely storing a jacket or spare layer for easy access. Sirrus 26 is the perfect pack for warm days on winding trails. Sirrus 26 is compatible with all Hydraulics™ and Hydraulics LT™ reservoirs.
