The Kosto THKF15 / THKF45 fire-resistant neck gaiter is a lightweight and comfortable protective layer designed to shield the neck from wind, cold, and incidental exposure to arc-flash energy. Made from a soft interlock knit blend of modacrylic, cotton, aramid, polyamide, and antistatic fibers, it delivers dependable thermal comfort while maintaining the protective qualities needed in industrial environments. Its breathable stretch fabric makes it easy to wear under jackets, parkas, or FR workwear without restricting movement, providing an essential layer of warmth and protection for outdoor or high-risk work.
