How It Works
Innovative Cooling Packs (ICPs) are inserted into dedicated pockets under the arms and on the upper back, targeting areas where body heat tends to build up.
What is the Innovative Cooling Pack (ICP)?
The Innovative Cooling Pack (ICP) is a reusable, non-toxic cooling pack designed specifically for wearable use. Unlike ice packs, ICPs provide steady cooling without direct ice contact, helping reduce heat discomfort safely.

ICPs are placed in dedicated pockets under the arms and on the upper back, targeting areas where body heat tends to build up.
Cooling Duration (Reference)
Cooling performance varies depending on environment, activity level, and individual conditions.
As a general reference, the Innovative Cooling Pack (ICP) may provide a cooling sensation for approximately 2-4 hours under typical summer conditions.
Results may vary.
