DuPont™ Tyvek® 400 TY450S Shoe Covers deliver reliable protection, comfort, and durability in demanding industrial and maintenance environments. Constructed from high-density polyethylene, the Tyvek® 400 fabric forms an inherent barrier against particles as small as 1.0 micron. These 5" shoe covers feature an elastic top for a snug, comfortable fit that prevents contaminants from entering footwear areas. Ideal for use in asbestos abatement, general maintenance, spray painting, and clean-up operations, they are lightweight, breathable, and designed for long-lasting performance without films or laminates that can wear away.
