Osprey Sirrus 36 Backpack

Sirrus 36 brings true innovation and quality to the ventilated pack world.

Ensuring you get your kit from point a to point b, the Osprey Sirrus 36 Backpack is the perfect partner for outdoor adventures. Constructed using 210D Nylon Crosshatch fabrication, the backpack is lightweight and highly durable. The durable nature of the fabric works to resist wear and tear so you can continue with complete confidence as you explore the unbeaten path. As well as this, Osprey's signature AirSpeed ventilated back system has been used within the construction of the pack to provide increased comfort in warm weather. The AirSpeed system is fully adjustable and combines a single-piece back panel and hip belt to ensure comfortable load carrying at all times. The system also features a highly breathable suspended mesh which allows cool air to flow throughout the pack whilst, at the same time allowing hot, humid air to escape; this creates a perfect microclimate for your skin to thrive in. Furthermore, the Sirrus features a large 50-litre capacity that lets you store all your essential items with ease. To keep you organised on the go, the Sirrus boast an abundance of pockets and compartments. The detachable raincover stored in the bottom pocket increases weather resistance whilst a double-clipped lid opening with draw-cord fastening ensures easy access to your stored items. The side of the pack also has a single vertical zip which allows access directly into the main compartment, saving you from having to open the lid top. 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 base of the pack also features a zippered sleeping bag compartment with a bellowed divider, designed to allow easy separation of equipment. Twin zippered hipbelt pockets stores small essentials whilst an internal hydration sleeve is perfect for a bladder. On the sternum strap, an emergency whistle gets you race ready and allows you to alert authorities if you get into trouble plus, an internal key attachment clip safely stores your keys. Trekking pole and ice axe attachment points make the Sirrus ideal for a multitude of sports. Lastly, side compression straps allow you to cinch down the fit for a comfortable fit.
