Duck Carpenter Pants in Slate
Carpenter pants in duck, relaxed through the leg, with the hammer loop and rule pocket that give the style its name.
The carpenter layout is not nostalgia. A loop on the leg keeps a hammer out of a pocket where it bangs against everything, and a long narrow pocket takes a rule without folding it. The duck is unlined, so these are year-round trousers rather than winter ones, and the fabric has enough give to make a full crouch comfortable. Slate is a colour that hides site dust better than black manages.
Buy the waist you actually wear. Relaxed here means room through the seat and thigh, not a loose waistband, so there is no need to size up. These are trousers for people who use the pockets, and if you do not, a plain work pant will suit you better.
