Massif Cool Knit Bottoms - FR



Massif Cool Knit Bottoms - FR

Our Cool Knit bottoms are Massif's lightest weight, silkiest base layer.

The perfect baselayer, Cool Knit aggressively wicks sweat away from your skin, keeping you cool and preventing saturation. Cool Knit meets NFPA standards for vertical flame resistance, but it's so soft and comfortable you'll forget it's FR. The lightweight four-way stretch bottom has a trim fit, retains its shape over time, and is highly compressible for easy stuffing when you're living out of a pack. Constructed with DuPont Nomex - the first flame-resistant fiber selected for use in military uniforms. 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.

NOTE: We don't normally keep this item in stock. Orders usually take 1-2 weeks.
