The ladies' Phenix Amanda Hybrid Ski Jacket with four-way stretch material is insulated with Dözen France Duck Down and a sophisticated Thunderon Digenite Thermo that can not only keep you warm, but also generate heat by absorbing infrared rays from the sun. 3-D Air Cutting Technology greatly reduces ""wear pressure" around the shoulders resulting in a jacket that feels a lot lighter than it actually is. The Phenix 10,000 membrane offers good waterproof and breathability for all day comfort on the snow.
