Tyvek® garments are composed of flash spun high density polyethylene which creates a unique, nonwoven material available only from DuPont. Tyvek® provides an ideal balance of protection, durability and comfort of any limited use fabric technology. 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. One size fits most.
