Tired of Feeling Hot and Uncomfortable?

Portraying Mrs. Claus, Santa, Christmas performers, or children entertainers means long hours in hot, heavy suits, wigs, and beards, often under bright lights, in crowded malls and theaters, or outdoor festivals.

Overheating can cut your appearance short, drain your energy, and make the experience less magical. But with ThermApparel's Cooling Vests and Cooling Gear, you can say goodbye to discomfort and hello to a more enjoyable performance.

ThermApparel’s lightweight, discreet cooling gear is designed to keep Christmas performers comfortable without interfering with their look, movement, or holiday spirit.
