Rab's Downpour Eco series consists of apparel with an uncanny combination of burly waterproofing and environmentally thoughtful designs, and the Women's Downpour Eco Pants are no exception. Rab made them with a thin, light, and packable 2.5-layer Pertex Shield membrane, which showcases extremely high waterproof, breathable ratings. You can count on them whether the weather's a spring shower or a downright downpour. All the materials used in these pants are 100% recycled, and even the DWR treatment is free of fluorocarbon toxins. It's little details like this that lower our impact and carbon footprints for hikers and trekkers who love the world they explore. The Downpour Eco Pants also feature knee-length side zippers and an elastic waist to ease slipping on and off at a moment's notice.
