The Portwest S481 Iona Lite Rain Trousers are lightweight overtrousers that go on over your work trousers when the weather turns. They keep you dry and act as a chillproof layer against wind and rain.
Side pass-through pockets let you reach items in the trousers underneath without taking anything off. Reflective tape helps you be seen, and the abrasion resistant oxford polyester stands up to everyday wear.
