The Fission delivers a high level of warmth with waterproof, breathable Gore-Tex protection. Designed for severe weather versatility, the thermally efficient construction pairs Coreloft Continuous synthetic insulation with a highly air-permeable liner to allow vapour to quickly reach the Gore-Tex membrane. This improves breathability without sacrificing warmth. The hardwearing Gore-Tex outer shuts out rain, snow and wind, and the insulated DropHood and collar add protection and warmth.
Redesigned to include an internal mesh dump pocket and a zippered security pocket, Coreloft Continuous insulation and N80p-x 2L Gore-Tex fabric.
