Outstanding meets practical with the Sorcery 55. This sturdy and reliable pack is crafted for the alpinist carrying for a rigorous day's ascent. Featuring ice axe and ski loops, a crampon pocket and an easy to access fleece lined optics pocket, you can keep your gear safe and close by no matter what backcountry conditions you tackle. 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.
