Garments are composed of flash spun high-density polyethylene which creates a unique, nonwoven material available only from DuPont. Provides an ideal balance of protection, durability and comfort of any limited use fabric technology. Fabric offers an inherent barrier to particles down to 1 micron in size. Protection is built into the fabric itself, and there are no films or laminates to abrade or wear away. Tyvek® fabric's durability advantage over microporous film and SMS fabrics delivers consistently better barrier, even after wear and abrasion.
