Cool Knit Bottom

The perfect base layer, Massif Cool Knit Bottom aggressively wicks sweat away from your skin, keeping you cool and preventing saturation. The lightweight four-way stretch bottom has a trim fit, keeps its shape over time, and is highly compressible for easy stuffing when you’re living out of a pack. Constructed with DuPont Nomex brand fiber – the first flame-resistant fiber selected for use in military uniforms. DuPont Nomex fibers carbonize and thicken when exposed to the intense heat of a flash fire, creating a protective barrier that reduces or prevents burn injuries. The Cool Knit Bottom is so soft and comfortable that you’ll forget it is flame-resistant.
