Marmot Men's Superalloy Bio Rain Jacket

The Marmot Men's Superalloy Bio Rain Jacket is an ultralight, packable waterproof shell built for fastpacking and everyday wet-weather wear. Its 12D ripstop nylon uses 63% bio-based yarn, and the NanoPro waterproof, breathable membrane is paired with 100% seam taping and a PFC-free DWR finish to keep rain out.

Designed to disappear into a pack, the jacket stuffs into its own pocket and clips to a harness, while a water-resistant chest pocket keeps small items secure and accessible. A fixed hood with peripheral cord adjustment, an adjustable drawcord hem, and shaped bonded cuffs with partially encased elastic seal out drafts, and the regular fit is shown on a 5'11" model with a 40" chest wearing size medium.
