Waterproof Packability.

Constructed with 3-layer GORE-TEX Paclite fabric and weighing only 305-grams, the Alpha SL is a feather-weight, compressible, and entirely waterproof jacket built for alpine adventures. It comes in a trim-fit with e3D, which features articulation in critical areas for enhanced mobility. This jacket's weight and weatherproof build make it perfect for activities like ice climbing in the Rockies or day treks around Quebec's national parks. It comes with HemLock inserts that secure it to your harness and are removable if not needed. The helmet-compatible StormHood is adjustable and designed to move with your head when worn over your helmet, while providing superior weather protection. The front zipper and single exterior chest pocket are WaterTight. The jacket comes with a stuff sack that features a clip-in loop.
