This winter bib and brace is built for outdoor work where you need to be seen in cold, wet weather. A waterproof, breathable shell with mechanical stretch moves with you, while Insulatex Pro padding adds warmth without unnecessary weight.
The bib and braces detach, so you can wear it as bib and brace or as trousers. With 15 pockets, a hammer loop and two-position knee pad pockets, it keeps tools and small items close to hand through the working day.
