The Arc'teryx Ravenna LT Jacket has all of the dependability of a 3-layer shell, but with a little extra touch of coziness. Backed by the power of 3L GORE-TEX, this shell is durable, waterproof, and breathable. A thin flannel backer adds just a hint of warmth and makes the jacket feel soft and cozy on the inside. The Ravenna has a trim cut with a DropHood to keep your warm layers close to the body and provide an ergonomic, all-mountain style.
