When a blustery snowstorm or wet weather hits, just stepping outside can be an adventure. Be prepared for anything with the insulated and waterproof Women's Aitran Jacket. Marmot MemBrain® Eco waterproof/breathable technology repels intense, heavy rain, keeping you dry for hours. The inner layer features 3M™ Thinsulate™ Recycled Featherless Insulation, which is made with 75% recycled loose-fill fibers that feel just as warm as 700 fill power down, but still perform when wet. The removable hood and interior fleece cuffs provide extra warmth.
