These Gauntlet Gloves are made of soft Cowhide. You will love the look and feel of this leather. You will also love the warmth you get from them. We use real "Thinsolate by 3M" in our gloves, not the cheap substitute. These gloves are designed to go over jackets with a larger diameter sleeve at the wrist. If you have a jacket that you can never get your gloves over, this is your pair of gloves. Stay warm- Ride on!
