The North Face took the classic Men's Plasma ThermoBall Jacket and redesigned it to keep up with the high demand of the modern man. From attacking snowstorms head on to spelunking underground caves, the two layer HyVent membrane and fully taped seams keep water out and the heat in. Even if the temperatures drop and your fingers feel like they're going to snap off, the rest of you is toasty in the jacket's ThermoBall insulation. Instead of using a traditional method of production, the insulation is actually collected in fiber clusters that trap and retain heat in cold and wet weather. Despite this heavy duty protection, this jacket is surprisingly lightweight and able to compress into your backpack if temps heat up.With a semi fitted design crafted from flexible polyester face fabric, the Plasma ThermoBall Jacket offers close to skin comfort and rugged durability that's appreciated at the pub or when you're clinging to an icy face high up in the mountains. Adjustable cuffs and underarm vents create a personalized fit and temperature regulation, while the zip pockets on the front and an internal media pocket give you ample storage for music, snacks, and the tools you need close at hand.
