The Terrain Dryo jacket is waterproof, breathable and insulated. Specifically engineered with DRYOsphere and Dermizax technology which fend off wind and water but still allow water vapor to escape from the body, the Terrain Dryo will keep you comfortable and dry no matter what Mother Nature throws at you. Due to the smooth texture, lightweight configuration and high elasticity of Dermizax's smart, non-porous membrane, the fabric of the jacket is noticeably softer and extremely comfortable to wear. The synthetic Microloft insulation offers exceptional warmth without adding weight and enhances the jacket's breathability. Equipped with pit zips for venting and pockets for everything you need, the Terrain Dryo is perfect for endless hours on the mountain.
