Tyvek® 400 garments are composed of flash spun HDPE which creates a unique, non-woven material available only from DuPont. Tyvek® 400 provides an ideal balance of protection, durability and comfort of any limited use fabric technology. Tyvek® 400 fabric offers an inherent barrier against particles (down to 1 um in size). Protection is built into the fabric itself, there are no films or laminates to abrade or wear away. Tyvek® 400 fabric's durability advantage over microporous film fabrics delivers consistently better barrier, even after wear and abrasion. Applications include lead and asbestos abatement/remediation, general maintenance/operations, spray painting, general clean-up. Comfort fit design based on extensive wearer input to provide our most comfortable garment design that enables a greater range of movement while stretching and bending, provides a more tailored fit, offers reinforcement in high stress areas for fewer blowouts, utilizes a longer zipper for easier donning and doffing and an elastic waist to better position the garment.
