Massif® – Flamestretch® Sock System (FR)

The Flamestretch® sock system is comprised of two socks. The inner sock liner by Darn Tough® Wool is low-profile, comfortable, provides excellent moisture management, and is warm when wet. The over-sock constructed with Massif Flamestretch fabric is highly breathable and traps heat to keep your feet warm in the harshest conditions.

  • Full flame-resistant construction with proprietary Massif® fabric
  • High warmth to weight ratio
  • Warm when wet
  • Excellent moisture management
  • Design to work with Massif® Fire and Ice™ layering system

Donned primarily by cold-water rescue divers, the Flamestretch Sock System is designed to be worn under dry suits when warmth and FR protection is critical.
