Carhartt jeans

My husband as a carpenter works a lot of the nuclear shut downs that's when once a year or once every two years the power plants will shut down for repairs and or re-filling. On occasion they had put him in the big concrete steam towers. You never know he says what the weather will be  inside. Dressing with carhartt jeans and his carhartt cover all and jacket he says are the most comfortable and protective wear he uses.
