This is a somewhat esoteric jacket custom ordered from Johnson. Alan offers this unique "wrinkled" "twinsted" horsehide from Italy. It's an otherwise smooth and jerky horsehide, but underwent a wet-twist process to result in a super striated texture. This is an amazing leather in my opinion, feels very durable. These photos below shows its texture accurately. The color is a light russet but may look darker under different lighting. Body lining is wool.
Riri zipper. Asking for $400 plus shipping.
