What Our Gearhead(R) Experts Are Saying:"I always keep this jacket stashed in my hiking pack. It's super lightweight, totally waterproof, and has great ventilation thanks to the underarm zips. I love how it packs into its own pocket and doesn't take up space when I'm not using it. Great for sudden downpours or misty mornings on the trail."From rainy trailheads to misty city mornings, the PreCip Eco Jacket helps us stay dry without overheating. Marmot built this versatile shell with a recycled nylon ripstop fabric and their waterproof NanoPro Eco membrane, offering reliable protection that's as breathable as it is packable. Fully taped seams and an adjustable hood seal out rain, while a drop-tail hem and regular fit allow us to move freely under the clouds. When the sun comes out or the pace picks up, underarm zippers release excess heat and the whole jacket stows neatly into its own pocket. Whether we're backpacking, commuting, or chasing afternoon storms, the PreCip Eco keeps weather worries out of the picture.
