You've given me my Florida summers back!
"Guys, I just want to say THANK YOU SO MUCH for your cooling vest! You’ve given me my Florida summers back! I’m MS heat intolerant, so since my diagnosis in 2016, I hibernate in the summer. No more! Yesterday I wore the vest to Epcot on a 95°F day and I was perfectly comfortable. The vest is cool, cute (hey, I’m still a girl), lightweight and even gave me the added bonus of lumbar support during our 5 mile excursion of the park. I’m so grateful!" - Nicole, Florida
UnderCool is a game changer.
"One frustrating fact of cooling vests is that they tend to be bulky, clunky, heavy, and most announce their presence like a 6-pound cyst growing out of your neck. People don’t want to stare or ask questions... but then they stare and ask questions. ThermApparel is flipping the script and has designed a vest—the UnderCool—that is virtually completely hidden, weighs less than two pounds, and lasts longer than many of their larger, full-vest competitors." - Dave Bexfield, activeMSers
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 never thought I would wear a cooling vest and like it.
"Our house is well shaded and tends to stay cool in the earlier half of the day, but by 3 or 4 in the afternoon, it’s pretty toasty. I try and get house and yard work done in the mornings, but there is often more to do, and I have to wimp out. But putting the vest on in the afternoon to go out and weed the garden, paint the front door, or even try and tackle the infamous laundry pile really helps. I have been impressed with the vest and much to my surprise I have been using it on a regular basis!" - Meg Lewellyn, BBHwithMS.com
