Reusable FirstIce® provides uniform compression and coverage to reduce inflammation and heat starting from below the knee through the tendon , fetlock and pastern areas. FirstIce® packs mold to the horses legs for maximum coverage and stay cold for over 2 hours. FirstIce® is reusable. When you are done, simply place your packs back in the freezer. Within hours they are ready to use again.
THE TECHNOLOGY When First Ice® inserts freeze, small ice crystals form. Fully-frozen, the pack is fills with small ice crystals which look and feel like soft flakey snow, are malleable and conform to the horse’s body parts. As the pack freezes and the ice crystals form, the pack expands slightly and needs to draw in air through the patented insert/bag vent. The vent is designed to resist liquid flow into or out of the insert. The conversion of the liquid to solid, which occurs during freezing the insert, is what extends the time the bags stay below freezing. The patented formula of polymer granules eliminates the burning sensation associated with raw ice. FirstIce® inserts stay frozen for over to two hours. After use the inserts can be re-frozen. After extensive use the inserts become chunky – this is how you know when it’s time to replace them.
