Tyvek fabric's durability advantage over microporous film and SMS fabrics delivers consistently better barrier, even after wear and abrasion. 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. One size fits most Pack of 100
