Reversible, lightweight and with a ventilated spine, Cavallo's English All-Purpose pad provides a Tri-Density Solution for saddle fit and comfort. This pad is made of 100% Merino wool on one side, closed cell high-density foam on the other, and has a layer of slow-release open-cell memory foam in between.This unique layering arrests concussion within the pad before it reaches the horse's back, providing cushion and support for the muscular system where reflex centers lie. The high integrity foam is thin to allow the horse to move freely and unrestricted, enhancing the function of the saddle gullet to allow your horse a place to put his backbone and use his structure properly. Shock-absorbing memory foam will provide a gentle massaging action as it bounds back in anticipation of the next impact. Seat bone cues are easily transmitted for disciplines from Dressage to Jumping.
