KleenGuard* A20 Coveralls are made from Microforce* Barrier SMS, a breathable fabric that provides improved barrier protection on submircron-size particles for a perfect combination of protection and comfort. The tough, durable, cloth-like outer layer is an abrasion-resistant, spunbond polypropylene, and the middle layer is an intricate web of microfibers that filter out light, water-based liquids, and dry particulates. The coveralls are ideal for maintenance and general clean-up work, including asbestos handling, lead abatement, and fiberglass operations. They may also be used in laboratories, pharmaceuticals, food processing, and other manufacturing operations. Denim Blue. 24/Case.
