EUC Men’s Duluth Trading Co Double Knee Flex Overalls Rugged-but-not-rigid Double Flex® Bibs that let you bend, crouch and lunge without restraint. Even the adjustable straps are built with resilient elastic, so there’s no shoulder gouging when you pitch hay or swing a sledgehammer. Doubly tough double-layer thigh-to-knee chaps accept knee pads for comfort on low-down duty. To top it all off, there’s a passel of pockets from bib storage to carpenter, patch and coin pockets. Get a pair and double down on comfort and function!
