Stay cool when things start to heat up with the Cool Human™ Hands-Free Portable Body Cooler. While sweating through your shirt isn’t fun, overheating can actually be harmful to your health. Cool Human™ clips right onto your belt or pants and provides cooling relief. It works by blowing air upwards under your shirt, providing instant relief. Cool Human™ has three different air fan speed levels so you can find the right airflow for you. The clever design places the vent behind the clip. As a result, the air remains unobstructed even under your shirt. With a battery life of up to 14 hours, Cool Human™ will see you through even the most gruelingly hot days. Impressively, the device runs nearly silently so it won’t disrupt your day.
