An ideal one-quiver jacket for your next ski vacation, the ThermoBall Eco Snow Triclimate Jacket delivers on the promise of previous ThermoBall Triclimate jackets, only this time in an eco-friendly package. This 3-in-1 ski and snowboard jacket features a removable inner layer made with toasty synthetic insulation, letting you layer up when it's cold on the hill and then ditch the shell when you head into town for dinner. Likewise, on warm but wet days you can go solo with the outer piece and enjoy the breathable performance and waterproof protection of DryVent.
