Osprey Stratos 26 Backpack The Stratos 26 daypack is all about ventilation and comfort, featuring an AirSpeed trampoline mesh back panel and Spacermesh shoulder straps and hip belt. Carrying this comfortable pack will literally be a breeze. Designed for all-day comfort when hiking in the hills, the Stratos 26 features a fully adjustable AirSpeed ventilated back system whilst still giving enough room for spare clothing, food and the essential kit. Constructed using tough, durable nylon fabrics, the backpack is built to last. The main compartment is made from a super tough 210D Nylon Crosshatch that is finished with a water-repellent coating to ensure that your kit remains dry as you go.
