A week in the high alpine of the Wind Rivers requires ample gear and back support. Through wildflower filled meadows to glacier packed passes, the Osprey Xena 85 Backpack will support you through your 50 mile loop. Designed with the Airscape back panel, the mesh-covered lining provides breathable ventilation while keeping the load close to your back for comfortable stabilization. Interchangeable hip belt sizing lets you find the perfect fit for your body shape, while BioForm CM technology is custom moldable. The thoughtfully placed access points and organization pockets distributes the weight of the impressive load capacity, so with a correctly packed bag you can walk up steeper passes with sturdy balance. But when the trail starts to disappear, reach for you trekking poles from the easy to grab Stow-on-the-Go pole placement points. From a removable daypack, sleeping bag compartment, and a multitude of external gear loops, the Xena 85 has everything you need for long treks deep in the backcountry.
