The Sherpa Men’s Annapurna Hooded Jacket is a puffy jacket for keeping in the heat. Head outdoors for a hike, walk your four-legged pal or head to work, surrounded by the warmth of 3M Thinsulate featherless down insulation. It’s not down, but a synthetic material that mimics down, which allows it to be lightweight, packable and moisture-resistant. Features include an attached hood, zippered hand pockets and napoleon chest pocket, plus elastic bindings at the hood and cuffs. When not being worn, stuff it into the included stuff sack and then into your pack or messenger bag for later.
