This Zone Saddle pad has Zoombang, which is a semisolid material at rest. This allows it to conform comfortably to the horse and disperse saddle pressure evenly. Zoombang reacts to impact for instantly becoming rigid, dissipating pressure and protecting the horse's back. The breathable design remains securely in place, providing conformal layered protection. The hand woven, 100% New Zealand wool blanket top can be folded back for shim placement if necessary and lays clean and flat against the pad. This new technology in gel saddle pads is powered with a vented Zoombang insert that is scientifically engineered to dissipate energy, reducing injury and stress on equine athletes. Durable orthopedic grade felt bottom absorbs moisture, remains soft and pliable, and provides excellent shock absorption. This same saddle pad is available in a 3/4" thickness as well.
