Our M-200 is a classic jacket with a riding specific cut. These have a slightly shorter body length to accommodate the riding position with a tapered body from the chest down through the bottom sweep. The bi-swing back allows for expansion across the back and the internal windflap helps prevent wind travel through the front zipper. The 1.3/1.4mm thick cowhide is a semi-aniline chrome-tanned leather with a light finish. This leather doesn't require much to break-in and has a soft temper that feels comfortable from the start.
