These Sealtex Classic Winter Trousers are built for outdoor work in cold, wet weather. A waterproof PU-coated shell with welded seams keeps rain out, while a padded filling and full lining hold in body heat.
The fabric is durable and stretchy, with a wipe-clean surface that helps after muddy or messy work. A fully elasticated waistband lets you bend and stretch freely, and stud-adjustable hems close neatly around the top of your boots.
