With Osprey’s AntiGravity technology, Sirrus 36 features a fully adjustable AirSpeed ventilated back system that combines single piece construction of the backpanel and hipbelt with highly breathable suspended mesh, allowing for increased comfort in warm weather even with a heavy load. Sirrus’ backsystem also offers an impressive specific fit for women, with an ergonomically shaped hipbelt, harness, yoke and backpanel.
The classic styling and clean design, alongside an impressively comfortable carry makes the Sirrus 36 a favourite for walkers and hikers 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. The detachable raincover stored in the bottom pocket increases weather resistance and tough nylon fabrics ensure durability. Sirrus 36 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. The base of the pack also features a zippered sleeping bag compartment with a bellowed divider, designed to allow easy separation of equipment. The Sirrus 36 is the perfect pack for long days and lightweight overnight trips in warm weather.
