Made using a thick napped fleece. This brushed, piled polyester fabric stretches and relaxes. As a result, there's plenty of "give" that makes this wrap ideal for protecting the horse while allowing it to exercise with full freedom of movement. It's durable and washable for ongoing use. With velcro closure and folded ends. Your choice of regular (9 ft.) or pony (7 ft.). Sold in sets of 4.
