The UB344 is our regular slim fit: slim seat and thigh with a straight leg cut and sewn from 11oz raw black selvedge denim with a touch of stretch. Raw denim is famous for being uncomfortable when new, requiring a break-in period, but we made this fabric from an easy-to-wear 11oz standard weight fabric with 1% stretch for added comfort. Both the inside and the outside of the fabric are dyed black for a blackout aesthetic except the contrasting signature blue ear selvedge ID. Black Unbranded leather patch. Union Special chain-stitched hems. Hidden back pocket rivets. Black button fly. Made in China/Macau.
