The Portwest S251 Sealtex Ocean Trousers are classic waterproof overtrousers for outdoor work in heavy rain and foul weather. The Sealtex Ocean fabric is durable and stretchy, and its wipe-clean surface makes it easy to keep presentable after muddy or messy jobs.
A fully elasticated waist lets you pull them on quickly over your normal work trousers. Stud adjustable hems let you close the leg openings around your boots, so you can stay protected in wet conditions.
