With the Marmot Women's Cosset Component Jacket, you get two indispensable outerwear layers that are literally made for each other. The Marmot MemBrain® shell is excellent protection against water and wind, while the velvety 200 weight fleece liner keeps you snug and warm. Add the removable Storm hood and you’re ready for anything. The MemBrain® fabric balances the best performance in waterproof, breathable fabric with excellent durability and reduces internal condensation while increasing comfort by reducing the chilling effect caused by condensation build-up.
