DuPont’s Tychem ThermoPro combines the chemical protection of Tychem and thermal protection of NOMEX in a single-layer garment. Designed to help provide Hazmat responders with permeation protection against a broad range of toxic industrial chemicals and chemical warfare agents and to increase escape time from flash fires, it provides at least one hour breakthrough protection against 20 of the 21 standard ASTM chemicals. The respirator fit coverall has a drawstring hood and front zipper closure protected by a double storm flap and sealed seams. Available with and without socks in bright orange or gray.
