The women's Fission SV is the warmest waterproof jacket in the Essentials Collection, ideal for alpine and urban unpredictable winter weather. 2-layer GORE-TEX and durable face fabric are weatherproof and breathable. GORE seam tape keeps the jacket sealed. Coreloft Continuous synthetic insulation retains heat. A highly air-permeable liner allows vapour to reach the GORE-TEX membrane fast, creating a lightweight, breathable, and thermally efficient system. The Expedition fit with e3D patterning allows for easy layering. Functional articulation in areas like the elbows enhances agility. The jacket is equipped with an insulated DropHood, while an integrated fitted collar panel with laminated chin guard provides warmth and comfort. All outer zippers are WaterTight, and the centre front zipper is lightweight Vislon. There is a waist drawcord inside the insulated hand pockets which can be used to contour the jacket's fit. The drop hem features a drawcord that can be tightened to seal out chilly drafts.
