The North Face Men's ThermoBall Hoodie is an insulated jacket built to keep you warm when you're on the move. The North Face teamed up with PrimaLoft® to create ThermoBall™ synthetic insulation, and what a break through it has been.Light, fluffy, and ultra-compressible just like down, but with the added power of keeping you warm incase it gets wet. That means you just gained a new best friend out on the mountains, whether you're hiking, skiing, climbing or mountaineering. The outer nylon ripstop shell is 15D for durability and won't compromise the weight of the jacket. The whole jacket packs down super small, so you can pack it or wear it at your leisure. The hood and hem cinch down and the cuffs have a hidden internal elastic, all specifically for blocking drafts from getting inside the jacket. Layer up, the ThermoBall Hoodie is at your service.
