The invention that launched COOLSHIRT SYSTEMS LLC in 1987 was a cooling vest for surgeons to wear in the operating room. The company has spent many years working beside surgeons under hot operating room lights. With thousands of facilities worldwide that now use our COOLVEST System to help surgeons remain comfortable, focused, & perspiration free in the OR, COOLSHIRT SYSTEMS has become the standard for keeping surgeons and ancillary staff cool in the OR.
