Unique Cold Capsule⢠technology is scientifically proven to stay cold 3 x longer than gels. When fully frozen packs are filled with small ice crystals that look and feel like fluffy snow, allowing the pack to conform to the most intricate parts of the horse's legs and body. After use the inserts can be re-frozen and used again in just four hours. When packs begin to freeze solid they should be replaced.
