An ice pack dedicated to ice vests that keep cold for a long time.
Features a special multi-layered thermal insulation sheet that gradually releases cold air, extending the duration of the time and reduces the cold on the contact surface. The aluminum on the insulation surface reflects surrounding heat to reduce the rise of ice packs.
The ice pack gelling agent is a food additive type, so it is safe and safe for the human body. Environmentally friendly because it is incinerated and disposable.
Keeps cold for about 3 to 4 hours (depending on the environment used)
