Lowered core temps by a full 3 degrees.
"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!" - Charlie, Rochester, NY
I am able to battle the hot summer days doing what I love.
"I have MS but it doesn’t have me. Thanks to my ThermApparel cool vest, I am also able to battle the hot summer days with my boy, doing what I love, rein, cowhorse and cutting!!!" - Tanya, Saskatchewan, Canada
I can handle a simple workout routine.
"My body can’t take the heat; walking becomes impossible and who wants to stay indoors. Summer time means fun in the sun. Thanks to the UnderCool vest, I am able to be out and about. I probably have almost every type of cooling vest out there and none of them are as discrete nor stay as cool as the ThermApparel vest design. I have to avoid any rise in body temperature, so I wear the vest and I can handle a simple workout routine." - Angel
It helps to keep me cool during class and is nice and light.
"12 years into my MS I feel like I know all of the tricks. Before and during class I’m rocking my cooling vest under my tank top. It helps to keep me cool during the class and is nice and light. It helps cool me down faster so I can walk normally again and help me workout longer by allowing me to keep feeling my feet. Thank you ThermApparel!”" - Jessica
I can continue to cycle and not be laughed at from fellow enthusiasts.
"I began putting frozen water bottles in my jersey for long rides. This allowed me to ride hot southern days including humidity. Along comes my diagnosis of MS and the enemy of heat. Without my accidental (lots of ice in the back pockets) of my cooling jersey, I would have to give up riding. But, Thanks to your company’s cool vest, I can continue to cycle and not be laughed at from fellow enthusiasts..." - Dan
I cannot wait to use this vest more in games and while training.
"I participated in a wheelchair Rugby tournament over the weekend and used the UnderCool vest in every game. I took my temperature after each game and it was 98-99 range not over 100 degrees like prior to using the vest. I wasn’t soaking wet because I didn’t need to constantly pour water all over me to cool me. I cannot wait to use this vest more in games and while training (I especially look forward to training outside on hot days this summer, which is something I previously avoided at all costs)." - Tom
Works with your body.
When your body is hot blood vessels open up to allow heat to be released.
Ice and Gel Packs cause blood vessels to constrict, preventing cooled blood from reaching your core.
ThermApparel PCM cools the blood without constriction keeping your whole body cool.learn more
