Sure, you could call them 100% waterproof, but that’d be setting your sights fairly low. Cofferdam Weatherproof Pants are seam sealed and built with our highest-tier waterproof membrane to keep you dry in any adverse conditions while still venting sweat. They’re windproof, lightweight and more rugged than standard rain gear – the nylon fabric eats punishment on jobsites or when you’re tearing down the mountainside. Crouch Gusset® plus built-in flex keep you nimble. Put them on over proper layers, and you’ll be prepared for any attempt nature makes to turn your keister into hamburger.
