PROFLEX™

43 FR acrylic | 39 cotton | 15 Twaron | 2 spandex

Incredible comfort paired with outstanding performance. PROFLEX is inherently flame-resistant with four-way stretch, so protection never comes at the cost of movement.

Built for crews who wear FR every shift — proof that serious arc protection and all-day comfort are not mutually exclusive.

Fabric features

4-way stretch

Spandex content lets the fabric move in every direction, so bending, climbing and reaching never fight the garment.

Super soft

A cotton-rich hand that feels closer to everyday workwear than technical FR.

Sustainable

Built to outlast several cycles of cheaper gear, reducing how often a program has to replace garments.
