Actually, it's what ever your preference is. Zilco makes a quality, easy maintenance harness with great fittings. A man in our club has a 20 year old quality leather harness that is to kill for. The quality of the leather,
Fittings and the stitching are a work of art. However, I wouldn't want to have to take care of it....but that is just me. I would rather be driving than cleaning leather harness. Nothing beats quality leather for appearance and feel though. Beta is stronger, lighter and easy to maintain.
