When camping trips and ski sessions require more core warmth, The North Face Men's ThermoBall Insulated Vest is there for you, even though you'll probably have forgotten that it's stashed away in your pack. Weighing in at nine ounces, this vest packs the heat without the weight. PrimaLoft's innovative ThermoBall insulation has the best of synthetic and down insulation all in one. Synthetic clusters mimic the round clusters that make up down insulation to trap heat and retain warmth. It also compresses like down so you can stow the vest in its pocket and pack it without sacrificing space. But because it's synthetic, you stay warm even if you get wet.
The ThermoBall has a durable nylon shell that handles the wear-and-tear lifestyle of backpackers and skiers. Elastic bindings at the arm openings and hem keep the vest in place while you duck, bend, hike, sprint, climb, and play on the mountain. And two hand pockets are always there for you when you need to warm up your digits.
