First let me say sorry for the photos. It is very hard to take these. If you have bought from us before you know our product can't be beat.
  Carter Pet Supply Goat Driving Harness
 
This work harness is designed to be used to Drive a Wagon, cart, or sled and can  be used as a full harness for unattended driving. Never leave small children unattended in a wagon hooked to a goat.
 
Parts of the harness and their purpose
 
Breast piece: padded piece that actually does the pulling. Fits across the chest high enough it does not interfere with the goat’s movement but low enough not to choke the goat.

Breech 
 
Belly band: cinch.
Tugs: run from the chest piece to the cart. Snap on end should attach to the load or a rope around the load.
Back band: holds everything in place.
