AMTEX TC is Mount Vernon FR's flame resistant fabric collection of cotton/Tencel blends. AMTEX TC maximizes comfort and durability without sacrificing the protection demands of the FR industry. Fabrics feel lighter than they are, which enhances the comfort of the garment. Like cotton, Tencel is also a cellulosic fiber, but stronger. AMTEX TC offers all the comfort of cotton, but with added strength.
