Draper Canine Therapy® Dog Coats are a cool-coat for canines in a lightweight breathable design offering a convenient way to deliver therapeutic benefits to your canine for all day relief. Works great as a layering item or immersed in water to help cool even the hottest pooch. The Draper Canine Therapy Dog Coat contains 50% Celliant® (Polyester), 50% Hydrotec. Holofiber/Celliant is a polyester based fiber that contains a blend of microscopic optically responsive particles. These inorganic natural minerals work with the energy released from the body and are designed to recycle this energy back to the body to improve health and overall well being of the wearer. The natural minerals that make up the composition of Celliant are extruded into polyester when the fiber itself is being made. This process allows the properties of Celliant to last with the life of the product, and as such can never wash or wear out. Holofiber/Celliant has been clinically proven in three double blind “USA” based studies to help reduce pain, increase oxygen levels and help balance overall body temperature. The benefits of increased oxygenation have been known to reduce swelling and fatigue, increase strength and build endurance, aid in healing and faster recovery from physical exertion. Products containing Celliant have no adverse effects as they work directly with the body to make it more efficient and can be used continually. The Draper Canine Therapy Dog Coats are machine washable and dryer safe. They are available in a variety of sizes- S (12", 14", 16", 18", priced at $50.00), M (20", 22", 24", 26", priced at $60.00) and L (28", 30", 32", priced at $80.00). When measuring your dog, measure from the nape of the neck to the base of the tail.
