The World-Bio 2 Horse Leg Ice Packs are perfect for cooling down your horse’s legs after exercise or for treating arthritic joints. These ice packs are made with a smooth nylon lining to protect your horse’s skin, and they have four elastic extended hook straps that determine the amount of compression applied to the leg. The sponge outside will keep the ice pack cold long time, while the insulated frozen gel pockets keep the boots colder even longer.
