The Cool Xchange is designed to help you recover from sprains and strains faster by combining cooling and compression in one. With an ongoing shoulder injury it was a little bit awkward trying to find the right way to wear it to suit, but with a little testing I was able to find a happy medium and the relief was almost instant. The Cool Xchange is reusable, doesn’t need to be put in the fridge and can be used anywhere, anytime (although I’d probably not use it on your shoulder if you’re heading to a cocktail party). It cools for around 2 hours, feels great when its on there and comes in a range of sizes to suit various ailments.
