Arc'teryx's Atom LT Hoody is one of the most popular pieces in their Essentials collection, and for good reason. A Coreloft insulated jacket keeps you warm for mid-level activities, and fits smoothly and comfortably as a mid-layer for colder days. Light, soft Tyono provides breathability that's necessary for skiing, while a DWR finish keeps moisture from seeping in. For higher exertion or warmer weather, the smooth faced, air permeable fleece stretch side panels allow heat to escape quickly. When the weather takes a turn, pop up the adjustable, insulated, low profile StormHood to keep the elements out.
