Designed to harness Osprey's AntiGravity™ technology, the Osprey Sirrus 36 features a fully adjustable AirSpeed™ ventilated back system, using a single piece backpanel sitting over a suspended mesh airflow system. This increases comfort in warmer weathers, evenly distributing airflow throughout, even when carrying a heavier load.
Clean, sleek, modern design makes the Sirrus 36 a favorite amongst hikers and backpackers, with plenty of capacity to store camping gear and layers when the weather takes a turn for the worst; In these inevitable situations, Osprey have included a detachable nylon raincover for weather resistance, giving your gear an extra layer of protection.
Standout features of the Sirrus 36 include base zipper entry for access, an internal hydration sleeve, Stow-on-the-Go™ trekking pole attachment and removable sleeping pad straps to attach a roll mat without compromising on space.
Sirrus 36 is compatible with all Hydraulics™ and Hydraulics LT™ reservoirs.
