    Phase-Change & Ice Cooling

    Phase-change and ice cooling use a frozen or set-temperature pack that absorbs body heat as it melts or changes phase — steady, powerful cooling with zero power required. Phase-change (PCM) packs hold a comfortable, skin-safe temperature for hours; classic ice packs go colder for short, intense relief.
