Filson's Double-Layer Worksmith pants are built to do the kind of work you never will. A double layer of tripe-stitched, abrasion-resistant canvas covers the seat and leg fronts with slots for kneepad inserts for work on hard surfaces — or activities that might result in skinned knees. Two layered rear pockets, a hidden coil pocket in the waistband, seven belt loops, and easy-access front slash pockets make this the toughest pair of jeans you can get.
