The Massif® Cool Knit® Crew, made with DuPont™ Nomex® brand fiber, is Massif's lightest flame-resistant performance base layer.
The perfect base layer, Massif® Cool Knit® Crew 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. Cool Knit Crew is so soft and comfortable that you'll forget it is FR.
