FLEXSAFE™

75 FR acrylic | 19 Tencel | 6 spandex

A base layer built to breathe, stretch and perform in all conditions.

FLEXSAFE is inherently flame-resistant and developed specifically for next-to-skin wear, so the first layer a crew puts on is already protective.

Fabric features

Lightweight

Thin enough to layer under anything without adding bulk.

Breathable

Tencel content moves moisture off the skin as work rate rises.

Moisture wicking

Pulls sweat off the skin and spreads it to dry faster under outer layers.

4-way stretch

Moves with the body and stays put under outer layers.

Applicable standards
