A couple of years ago Lee Jeans launched their heaviest denim made so far in their collection, Lee 101z – 23oz. Lee Jeans launched their 101 cowboy pant in 1924, probably the first denim trouser designed specially for cowboys and rodeo riders. This same year they removed the back pocket rivets and added the bar tackings. After the 101b (buttons) they came with the 101z (zipper). The first denim pants with a zipper!This heavy 101z jean is made from 23oz right hand selvage fabric. The selvage is golden/brown. The jean was made in limited quantities, 250 pieces only! This is one of them.
