This Half Pad Ultra Open Spine is designed without lambskin around the spinal canal, making it ideal for use with custom saddles to allow for maximum spine clearance. It is suitable up to a 18" seat, and is an EXCLUSIVE ITEM on our website. Benefits include a genuine lambskin underside with an approximate pile depth of 30 mm, as well as our hard-wearing saddle pad fabric on the upper side. It is easy to adjust under the saddle and ensures a non-slip fit. It is also machine washable with a lambskin detergent and tolerated tumble drying.
