Sirrus 36 Backpack
Ready for your next trip to the peak, the Osprey Sirrus 36 Backpack combines all the essential hiking features alongside a spacious 36 litre capacity. Boasting a sustainable design made from Bluesign-approved materials, the pack boasts an injection-moulded suspension system w/ 3D-tensioned mesh that provides breathable support, while the taller, wider frame geometry and tailored adjustment system offers an extended fit range for day-long comfort. Â
Its panel-loading convenience also works in tandem with easy organisation that makes it perfect for short and long hikes on a variety of surfaces. You can rely on pockets on the lid, front, hip-belt and side, as well as a main and lower compartment, hydration sleeve and external trekking pole and axe loops. Additionally, compression straps reduce excess bulk and lash loops let you attach external layers should they get dirty or wet.Â
