Why Leather?

Lambskin is a lighter weight leather than deerskin so it molds to your body like a second skin. It is extremely tough and can be machine washed without a need for special detergent. The finish on the lambskin has a very small smooth grain which makes it very grippy on the saddle.
Deerksin being a thicker leather will provide you with a more structured feel to the breech. It has a defined grain on the leather which provides grip for your seat without being "sticky". Deerskin may also be machine washed but needs to use a pure soap product or breech wash to keep the leather from drying out.
