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.
