Armor for doing battle with the elements, the Arc'teryx Thorium SV goes beyond the traditional light down parka. Although it offers an athletic cut, the box baffle construction and plethora of down filling mean this is a bulky jacket. The robust materials used in its construction provide excellent weather protection and enhanced durability. This jacket is meant to be used as a stand-alone piece, and its bulky high loft construction guarantees that you will not try to layer over the top of it. Minimally featured, the Thorium SV owes much of its weight to materials. Made with 750 fill-power down, combined with 100 and 140 weight Coreloft synthetic insulation in moisture-prone areas, and a 40 denier ripstop fabric, the Thorium SV weighs around a pound and a half. This jacket is a beast on the beefier side of the light down jacket world.
This jacket received a colorway update for the coming winter season but otherwise remains the same jacket in every other way.
