Conditions change quickly in the mountains, and adaptability is key to staying prepared for whatever the weather throws at you. Understanding this, Osprey Packs built the Stratos 36 Backpack to be able to handle everything from sweltering summer days to spring storms, and quick day hikes to minimalist overnighters. It offers enough capacity for all-day treks, yet its streamlined design keeps it from feeling bulky on the trail. It also sports sleeping pad straps and a sleeping bag compartment for when the weather calls for a night under the stars in your hammock. Airspeed suspension includes an exceptionally breathable back panel to keep you cool through the hottest part of summer, while an integrated raincover offers protection from sudden downpours.
