For extended backcountry tours, Sierra Designs’ Ymir is a multi-day carrying machine. Perfect for a hut trip or overnight ski mountaineering adventure, the Backpacker Magazine Editors’ Choice Snow Award-winning Ymir features our CORE suspension system- an HDPE framesheet combined with dual aluminum stays- allowing comfortable carrying of all the backcountry essentials and safety gear. Quick-access pockets and compartments make it fast and easy to get snacks and water as well as probes and shovels in an emergency.
Sierra Designs’ Ascent and Descent series climbing and ski packs outperform the competition thanks to the CORE Suspension™ system. Blending an HDPE framesheet with strategically placed aluminum stays, CORE Suspension™ is more comfortable and supportive than other systems allowing you to ski longer, climb higher, and perform better.
