Like most of us, you have leather harness and tack, it works, it's beautiful, traditionalist' require it, as do some rulebooks.  Today, more and more judges allow the synthetics.  The work involved in maintaining leather harness is only one reason to switch to Biothane Harness.  Biothane has been used in the Equine industry - Harness Racing - since 1977.  Parry Harness & Tack was one of the original companies associated with Bioplastics, the inventors of Biothane.  Biothane like products are made in China, Australia and here in the USA.  Whom ever you choose to make your new harness, insist on Authentic, USA made Biothane.

Parry Tack coined the phrase: “Truly, the last tack you’ll buy.....    in that color”
