The TUG Jacket allows the TUG to be used indoors as a sled.  Durable Fleece and Velcro construction and "clam shell" design allows for easy addition and removal on any TUG.  Low friction Fleece material is a contoured fit that will provide protection of any indoor flooring surface (Hardwood, rubber, Mondo, etc.)  Bottom is dual-layered for additional strength and protection and tells you when it's time to order a replacement due to normal wear.  The TUG jacket may be washed if necessary.  For best results, wash in COLD water and dry with LOW heat setting.
