The Fission SV has been the toughest, warmest and most waterproof jacket from Arcteryx for years. Designed to make it more comfortable, stronger and just better.
The Fission SV features an utterly reliable Gore-Tex Pro outer shell with reinforced 3 layer fabric across the main abrasion areas with a lighter more breathable 2 layer Gore-Tex Pro fabric. Both these fabrics have a soft feel and move quietly to eliminate that annoying Gore-Tex rustle. Insulation is provided by their own Coreloft synthetic fibres which is zoned to optimise performance. Coreloft 100 g/m² is used under the arms to increase movement and increase breathability, whilst Coreloft 140 g/m² is used in the rest of the construction to maximise warmth. The benefits of Coreloft insulation is that it resists compression better than down, it is durable and resilient, and should the jacket become soaked, it will retain warmth and dry quickly.
A fully insulated and helmet compatible "Drop Hood" provides essential protection and is attached to an insulated high collar. When not required the hood "drops" out of the way leaving the high collar to provide warmth and seal out the wind. There are also plenty of storage options with two chest pockets, two hand pockets and two internal mesh pockets. All external pockets use WaterTight zips and the main zip has a WaterTight Vislon zip all of which are highly water resistant but not completely waterproof.
The Fission SV is the perfect all mountain jacket in hostile conditions or less strenuous activities when you just need the best protection available.
Arcteryx have applied their genius E-3D patterning which uses clever design and construction techniques to improve the fit, enhance mobility and reduce overall weight. The end result is that the Fission SV feels fantastic on giving you a real sense of comfort and protection. The Fission SV is cut to the Arcteryx Expedition Fit block which is large and over cut to allow for winter/expedition style layering.
