STAYONS Wraps are made using a patent-pending fiber-paper matrix that seals pre-filled quilted pockets with specific poultice ingredients. When activated by soaking briefly in water, the resultant gel mixture remains in place, forming a pliable poultice that holds moisture for and extended time and molds well around legs. When soaked in ice water, wraps provide cold therapy benefits for immediate acute injury/inflammation situations, and longer-term poultice benefits - all in one step. All wraps are lightweight and disposable. See item 048319 STAYONS Poultice Boot - to secure STAYONS Hoof Wraps.
