The UB421 is our skinniest fit: tight in the seat and thigh tapering to a very narrow leg opening cut and sewn from 21oz raw indigo selvedge denim. The Sanforized 21oz fabric is around twice as heavy as most denim, making it hardwearing and rigid when new but will soften and fade beautifully when broken-in. 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.
