The UB101 is the skinny fit: skinny seat and thigh with a straight leg cut and sewn from Sanforized raw indigo selvedge denim. The midweight 14.5oz cloth is heavier than most denim, but they 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.
