Customer Testimonials

I suffer from fibromyalgia and frequently use hot and cold to relieve pain. I have never come across a cold pack that stays as cold for as long as your brand does.

E. Stengel, Atlanta GA

I was at a rugby tournament today and witnessed a nasty accident as a burst ‘ice bag’ sprayed ammonium nitrate into a boys face. He was fine after treatment but I am keen to source a cool bag such as your non-toxic, latex free InstaKool in the UK.

Dan C. , United Kingdom

Your product is so good, versatile and such a good ice pack to lay on because it is soft. This is the kindest ice pack or heat pack that I have ever used in my 58 years.
