Engineered for extra insulation and loft, the Coldsnap Down Jacket combines RDS-approved natural down in the body and sleeves with an 85% recycled VerticalX™ Eco technology strategically placed in the shoulders and cuffs for reinforced warmth and water resistance. The lightweight 53% recycled ripstop Pertex® Quantum Eco shell blocks wind and resists rain and snow at base camp or while exploring around town.
