FR Fabrics with Motion, Created for Comfort

FlexTex is Mount Vernon FR’s collection of flame resistant fabrics developed for increased comfort and mobility. FlexTex fabrics include an elastomeric fiber that allows fabric to flex up to 14% with a 97% recovery. The elastomeric fiber adds mobility to fabric with no reduction in FR protection, so workers experience increased freedom and range of motion in their flame resistant clothing. Mount Vernon FR FlexTex fabrics have a bilateral flex that allows them to elongate sideways and diagonally, eliminating any sagging or bagging.
