Why We Like The Patagonia Altvia 36L Backpack

Whether we're spending a night on the trail or hopping from shelter to shelter, the Patagonia Altvia 36L Backpack keeps our gear safe, organized, and easy to transport. The largest in the Altiva lineup is essential for stashing our streamlined kit and keeping us comfortable along the way. A supportive frame, suspended mesh back panel, and ultra-breathable airmesh shoulder straps assist with load-bearing and wick moisture for all-day comfort. Rugged nylon offers abrasion resistance for rough trails, and an included rain cover offers protection against wet weather—even better, both are made from 100% recycled content.
