The Arc'teryx Men's Atom Hoody is Alpine proven as a midlayer or standalone jacket. This versatile hoody has warmed climbers and backcountry travelers for years and is made to last even longer. Built to handle a range of conditions and output levels, the latest-generation Atom’s Coreloft Compact insulation retains its warmth even if wet and has loft retention to withstand years of packing and unpacking. The water resistant Tyono 20 face fabric is breathable and durable, stretch side panels improve fit and freedom, and the insulated StormHood adds warmth.
