Thank you for your inquiry about our products.
Our gel packs contain a unique XC Gel® formula which allows the gel packs to retain a safe 32°F/0°C to not risk 'cold burns', the temperature remains consistent throughout a treatment as well as stays pliable even when completely frozen. Our gel packs also come with a wrap to help keep it in place during a treatment and offer mild compression to ensure the cold is focused down deep into the tissue to bring down inflammation around the injury. Each one is specifically designed to mold around the shape of the body part in which it is treating as well.
I hope this information was helpful for you. Please contact us if you have any further questions or concerns.
