Osprey Stratos

The Stratos series features an AirSpeed back system with taut mesh. This back system offers unparalleled ventilation and comfort during your hiking tours. The ventilation cutouts in the EVA foam of the SpacerMesh shoulder and hip straps provide additional airflow. All Stratos models come with an internal hydration reservoir compartment, where the hydration bladder can be easily stored, allowing you to stay hydrated, especially on hot days. The AirSpeed carrying system consists of an aluminum alloy LightWire frame and a taut 3D mesh back. Side crescent-shaped cutouts provide extra ventilation. All contact surfaces are either covered with breathable mesh fabric or made from perforated and molded waffle foam. Whether you're climbing a 4000-meter high mountain, hiking along the Rennsteig, or participating in a 24-hour race, this backpack sits comfortably and won't shift. The innovative Stow-on-the-Go attachment allows trekking poles to be stowed on the side of the backpack, so the hiker doesn't have to stop or slow down. For the backpack to deliver on its promises, it must fit properly and comfortably. Body weight and height cannot always be equated with specific sizes, as people of the same height often have different back lengths, hip widths, or shoulder widths. Size: M/L.
