The Stratos 26 litre Backpack is designed to be comfortable even on a warm summer day. When the backpack is full and heavy, comfort isn't compromised as the Osprey anti-gravity system provides breezy lumbar support on the back. In addition to that, the Airspeed System creates a space for further ventilation between the pack and your back increasing comfort during long walks. The Stratos 26 is made from long-lasting weather-resistant nylon fabric and comes with a rain cover in the bottom pocket for added rain protection.Internal key attachment clipUnder lid zipped mesh pocketTwin zippered hip belt pocketsSternum strap with emergency whistleSingle ice axe loopSide compression strapsVertical centred zippered pocketAdjustable AirSpeed ventilated trampoline suspended mesh back panelAdjustable torso lengthInternal hydration sleeveIntegrated & detachable rain coverStow-on-the-Go trekking pole attachmentTop lid access26-litre volume More info
