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.
When space is tight, the jacket stuffs into its own pocket so it can be clipped to a harness or packed away, while the fixed hood with peripheral cord adjustment, adjustable drawcord hem, and shaped bonded cuffs with partially encased elastic seal out drafts. A water-resistant chest pocket keeps small items secure and accessible, and the regular fit is shown on a 6'0" model with a 38-inch chest wearing size medium.
