Sitting still doesn't stop the heat. Whether you're in a wheelchair, behind the wheel through a long shift, or trying to sleep through a hot night, the surface you rest against traps warmth exactly where the body struggles to shed it. Cool Flow® seats and blankets circulate ice-chilled water through lines sewn directly into the cushion or blanket, so cooling continues for as long as the system runs — no packs to swap, no warm-up, no interruption.
