The crupper tube material is currently on backorder, and I'm not sure when it will arrive. Cupper tubes will then need to be made before cruppers can be assembled. No ETA at this time yet, I'm sorry!
This Crupper is made of soft neoprene around a beta biothane strap. The neoprene won`t rub the soft skin under your horses tail. The beta biothane strap from the ring to the saddle is flexible and easily adjustable.
You can choose from black, brown, blue (royal), lime green, red, yellow, pink, violet, wine, pastel green, pastel purple, or saddle brown beta biothane and solid brass, nickel plated or stainless steel hardware ($3 upcharge for this expensive metal/hardware).
Shown here in Red Beta with Solid Brass hardware.
