Engineered for Intimate Protection

This fabric addresses the critical need for protection in high-risk environments while solving the comfort challenges of traditional FR layers:

Inherent FR Modacrylic Core: Provides reliable, permanent flame resistance that is built into the fiber, ensuring lasting protection that will not wash out or degrade with proper care.

Breathable Lyocell Layer: Adds vital moisture-wicking and temperature-regulating properties, pulling sweat away from the skin to keep the wearer dry and reduce heat stress—a crucial factor for comfort in protective undergarments.

High-Performance Spandex Integration: Delivers exceptional 4-way stretch and excellent recovery, ensuring the fabric moves seamlessly with the body, eliminates restrictive feel, and maintains a secure, comfortable fit throughout movement.
