Lightweight storm shelter and hyper climate-controller, the Stoic eVent Stash Shell stands up to Mother NatureAAAs nastiest without weighing you down. Barely noticeable in your pack as a just-in-case option, the eVent Stash Shell tags along anytime and any season you see clouds on the horizon. StoicAAAs 3-D ergonomic fit ensures maximum mobility minus the feel-like-a-sail-in-the-wind factor, cutting down on material on bulking up on dynamic fit. Pull up the fully-adjustable, helmet compatible hood when the storm hits, and say a quiet thanks the folks at eVent for making such an incredibly breathable, lightweight, yet totally weatherproof fabric.
