Crossbuck is a type of pack saddle that is usually rigged for a double cinch and is best suited for carrying hanging panniers. The crossbuck is the saddle that most people think of as a packsaddle and the type you see in pictures of prospectors and mountain men. The bars (the sculpted horizontal pieces that lie against the animal’s back) are joined by a pair of hardwood crosspieces front and back that form an X. This looks like a sawbuck used for cutting firewood, and has resulted in another name for the crossbuck saddle, the sawbuck.
