The Flamestretch® Pant is Massif's warmest layering option. Designed to be an insulating layer worn over Cool Knit™ and/or HotJohns® garments. Flamestretch fabric is highly breathable while trapping heat to keep you warm and comfortable.

Constructed with DuPont™ Nomex® brand fiber, the first flame-resistant fiber selected for use in military uniforms. Nomex fibers carbonize and thicken when exposed to intense heat of a flash fire, creating a protective barrier that reduces or prevents burn injuries. When operating in cold conditions, Flamestretch Pant is the ideal choice.
