The UB401 is our skinniest fit: tight in the seat and thigh tapering to a very narrow leg opening cut and sewn from Sanforized raw indigo selvedge denim. The midweight 14.5oz cloth is heavier than most denim, but we think it’s the perfect weight for year-round wear. Rope-dyed indigo exterior warp yarns and white interior weft yarns create a quintessential raw denim fabric. Signature blue ear selvedge ID. Unbranded leather patch. Union Special chain-stitched hems. Hidden back pocket rivets. Copper tin button fly. Made in China/Macau.
