Inspired by Osprey’s AntiGravity™ technology, Sirrus 50 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 50 a firm favourite for walkers and hikers and campers who are looking for a ventilated daypack with enough capacity for camping equipment and overnight gear, as well as plenty of extra layers and equipment for when the weather is changeable. The detachable raincover stored in the bottom pocket increases weather resistance and tough nylon fabrics ensure durability. Sirrus 50 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. The side of the pack has a single vertical zip which allows access directly into the main compartment, saving you from having to open the lid top. The base of the pack also features a zippered sleeping bag compartment with a bellowed divider, designed to allow easy separation of equipment. Sirrus 50 is the perfect pack for long days and lightweight camping trips in Spring, Summer and Autumn.
Sirrus 50 is compatible with all Hydraulics™ and Hydraulics LT™ reservoirs.

Santa Cruz, California, 1974. Mike Pfotenhause sits down at his sewing machine and embarks on a challenge. A challenge to create an innovative backpack that is complex enough to move with the body. From a head full of ideas and a burning passion, Osprey was formed.
Fast forward to today, Mike’s one-man vision has grown into a wide range of Osprey rucksacks and accessories that are being used from the highest of mountains to the remotest of islands and everywhere between.
Osprey only design and produce high quality products that are built to last. Innovation is in every strand of each pack and an identity born out of true specialism, Osprey continue a true pioneering spirt that it started with in 1974.
