The UB455 is our skinniest fit: tight in the seat and thigh tapering to a very narrow leg opening cut and sewn from 12.5oz black selvedge chino twill. Most chino fabrics weigh around 7-10oz per yard, but our burlier Black Selvedge Chino is closer to a standard weight denim at 12.5oz per yard. Signature blue ear selvedge ID. Unbranded leather patch. Union Special chain-stitched hems. Hidden back pocket rivets. Black button fly. Made in China/Macau.
