The Portwest S650 is a waterproof overtrouser for work in wet conditions where light chemical splashes are a risk. Its breathable, windproof fabric keeps rain and wind out, and its antifungal treatment helps keep the trousers hygienic between wears.
The knitted fabric stretches as you move, has high tear and tensile strength, and wipes clean after a dirty shift. An elasticated waistband and stud-adjustable hems let you pull them on quickly and keep them secure.
