These high-quality Half Pads are made of 100% natural Australian Merino lambskin. The wool is much denser and softer than the older sheep's wool used in many coasters. The spine is shaved short, relieving pressure on the spine and allowing airflow. Half Pads are best sellers because they can be used with any type of saddle. They can be used on a thin saddle pad or directly on the horse's back. In addition, the half-pad is equipped with two 'cuts' at the front so that the D-ring straps of the saddle pad can be passed through the half-aisle.
