This reusable pack utilizes a patented Propylene Glycol formula which is food grade for quality assurance and non-toxic properties. The non-gel formula stays soft and configurable when removed from the freezer, conforming to the horse's canon bone, tendon and hock.

It stays cold for up to 2 hours in Ice Horse® wraps.  Because there are also times when heat therapy is called for, the pack can just as easily be used for targeted heat application.
