These durable DuPont chemical coveralls are made from innovative Tyvek fabric that offers breathability and Comfort while still ensuring protection. Suitable for sensitive work environments that require exacting standards of particle and microbiological contamination control, they feature internally stitched seams to prevent contamination from sewing yarn. Elasticated cuffs, ankles and waist provide a close fit that allows workers to complete tasks in Comfort without obstruction, while the collar and zip flap provide extra protection.
