The Shires Ladies Berkeley Wide Waist Breeches are made from performance fabric that's comprised of 67% cotton, 25% nylon, and 8% Lycra. The fabric may be innovative and stretchy, but it's still machine washable for easy care. The Shires Ladies Berkeley Wide Waist Breeches feature a Euro seat and a low-rise style, which still provides you with the coverage you need in the saddle.
