ThermApparel is a proud manufacturer of lightweight cooling products that work.

Our products utilize Phase Change Material(PCM) that freezes between 66F and 70F(19-21C) to help keep your body cool and comfortable for long periods. One of the Coolest (pun intended) parts of using PCM is that, unlike evaporative cooling products, our lightweight solutions also work in humid conditions or under other clothes that prevent airflow.

Many other PCM and Ice Cooling Products weigh well over 5 lbs, making you work extra hard to wear them. Our solutions generally weigh half that and provide the same cooling duration.
