Ultralight and incredibly versatile, the Alpine Start Jacket uses Scchoeller® stretch-woven softshell fabric to provide highly breathable, weather resistant protection for alpinists and adventurers. Gusseted construction allows complete freedom of movement while climbing or running in the mountains, and the highly packable design stows in its own chest pocket when not in use. A carabiner loop lets you clip it to your harness or pack to take with you on missions.
