    What clients say

    • The vest is awesome!

      Ten minutes in to a regular fursuit photoshoot id be sweating, but we were talking photos for 2 hours and I didnt break a sweat. Its also really lightweight and comfy and at one point I forgot I had it on

    • Big thanks for the ThermApparel cooling vest!

      Lowered core temps by a FULL 3 degrees from the am race (no vest) to the afternoon race (with vest) and ten degrees warmer ambient. Couldn't wait for the am race to be over. I could have gone double the laps in the afternoon with the vest. It works, period!

    • Love my Cooling Vest, never have to worry about overheating again. It's so slim it's invisible under my vest or Santa Coat. Keeps me cool during those home visits sitting near the fireplace or in the hot sun at the Christmas in July events. My TherApparel Cooling Vest will always be part of my Santa Outfit, summer and winter.
