Aprons feature a five-layer fabric compacted into 2.7mil. Fabric is impervious to at least 90% of all organic chemicals for four hours at 35°C (95°F). Each layer acts as a barrier against various epoxies and industrial chemicals. Coat aprons are cut from a single piece of film to prevent penetration of liquid chemicals. Sleeves have flexible wrist openings. A buckle closure is attached to the integrated neckband, and the aprons feature two waistbands that are tied in the back. Each weighs less than 198g (7oz).
