An ultralight softshell designed to shield weight-conscious climbers from ridgeline gusts and light weather, the Black Diamond Alpine Start Hoody features Schoeller stretch-woven fabric to provide highly breathable and highly packable weather resistance. A gusseted construction offers unrestricted freedom of movement, while the adjustable hood fits over a climbing helmet. The jacket also stuffs into its own chest pocket, which features an internal carabiner clip loop for attaching to your harness.
