Born in the city, built for adventure

Think of the Fundamental Shell as your new year round, go-to piece. This lightweight alpine mountaineering shell features a tailored cut for a flattering, close-to-the-body fit, large front pockets for plenty of room for all of your stuff, and a cutting edge, helmet-compatible hood. Its waterproof, breathable 3-layer fabric construction makes it perfect for rainy days in the city, snowy days in the mountains and everything in between.

By itself or layered, the Fundamental Shell is ready for adventure in any conditions you might encounter.
