From the manufacturer

The Marmot Precip Eco Jacket is lightweight, breathable & waterproof. Similar to the Precip Jacket, the Eco is made from recycled material & PFC-Free DWR. The Marmot PreCip Eco Jacket lasts longer than before due to the advanced technology in the microporous coating of the jacket and is small enough to stuff into its own pocket. With an updated fit, DriClime™-lined chin guard wicks away moisture to help prevent chafing, and the same features you know and love from Marmot's PreCip Jacket (stowable hood, adjustable hem, and heat-releasing PitZips), this is a great jacket to accompany you on any adventutre.
