Who needs double-knee anyway, with a pair of Carhartt single knees, these puppies are so durable you won’t ever think about it. Doused in a positively gorgeous botanic green, these pants are cut from organic ‘Dearborn’ cotton canvas and finished with four pockets, and two thigh patch pockets. It even comes with a hammer loop for carrying your breezer or a nice stick you found on a walk.
