Our "lifetime warranty" covers failure of craftsmanship, materials and manufacturing defects, which includes belt loops and seam stitching. It does not include wear and tear, such as colors fading, scuffs on the pockets or the back of the pant created from general friction over the years. Simply ship the pants back to us, with your proof of purchase, and we will happily repair or replace your pant with a new pair. This decision is subject to our discretion on the severity of the defect. In the case that the style has discontinued, you may be provided with a similar pair.
