A truly multi-talented jacket for use in cold, wet weather: the Fission SL Jacket by Arcteryx!
This jacket is insulated with exclusive ThermaTek fiberfill by Arc'teryx. The Canadian high-end outfitter has spared no effort on the development of this special fabric! The result is a very plump polyester material, treated with a durable waterproofing so that it absorbs virtually no moisture. The jacket also consists of a soft, very wear resistant Gore-Tex outer material that is guaranteed to be durably weather proof. The insulation is laminated onto a backing fabric (not quilted) which means that no cold air can get in. The fill-weight of 90 grams sounds low, but in fact produces an enormously high thermal output (thanks to the impressively plump insulation).
This makes the Fission SL is especially suited to colder weather above freezing point, in pouring rain and sleet. The lined storm hood with reinforced peak and high-closing collar offers effective protection from the elements!
The weight of the Fission SL is exceptionally light for such a warm and weather proof synthetic jacket, so you will barely notice carrying it! The other details are just what you would expect from a hardshell or winter jacket. Adjustable cuffs, hem drawstring, practical pit zips (a rarity in lined jackets!), a longer cut in the back as well as large inside pockets for gloves and thermos.
With the Fission SL winter jacket you will be perfectly equipped for all cold-weather mountain adventures and when the going gets tough, this jacket keeps going!
