Arc'teryx Fission SV Jacket for Men

Insulated, fully waterproof, and tough, the Fission jacket delivers a high level of warmth with breathable GORE-TEX protection. Designed for severe weather use (that's where "SV" comes from), the thermally efficient construction combines Coreloft Continuous synthetic insulation with a highly breathable liner to allow water vapor to quickly reach the GORE-TEX membrane, where it is then vented to the outside to keep you dry and comfy. Wet down feathers simply cannot function well when they are clumped together by moisture, so synthetic insulation is a much smarter choice in situations where you'll be wet and cold. The hardwearing GORE-TEX shell shuts out rain, snow and wind, and the insulated DropHood and collar add protection and warmth right where you need it most.
