“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.”

“It’s awesome and helps me get out of the house.”

“I’m a 49 year old women with progressive MS. This vest works fabulously. I live where the heat reaches 105°F+. So I can honestly say this vest helps immensely. But overall it’s awesome and helps me get out of the house.” 

Kim

“I am not overheating while trying to dry my hair and get ready.”

“I have a difficult time getting showered, dressed and out the door in a timely manner without having to stop and rest. I decided to put my vest on after my shower and it has made a huge difference for me! I’m not overheating while trying to dry my hair and get ready. This wasn’t a use I had planned on, but it sure does make a difference in my day-to-day life.”

Laura

“It doesn’t call attention to my MS.”

“This company, made up of only three dedicated peeps, created (THANK YOU) a cooling vest that fits like spanks and doesn’t call attention to my Multiple Sclerosis! And I keep finding new ways to use. The latest is-playing my ukelele on my porch! People who’ve had chemo, or have Lupus or other chronic diseases can benefit from it as well. God bless you! It’s a blessing! Thanks ThermApparel!”

“I was able to attend Country Thunder Outdoor Music Festival.”

“Thanks to my vest, I was able to attend Country Thunder Outdoor Music Festival this weekend. MS wasn’t slowing me down and making me miss out on some great country music thanks to ThermApparel. P.S. I’m the blond.” 

Tanya

“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

“I love how hidden it is.”

“This cooling vest is a gem I’m currently crushing on. You actually wear it UNDER your clothes! I love how hidden it is (you literally can’t tell anyone is wearing it) and how chilly it kept me!” 

Dr. Gretchen

“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

“It kept me from melting entirely!”

“Got my Kung Fu punch, my Limoncello cocktail and my lobster roll all traditional favorites. Also saw 98°F (in 98°F heat) so thank God for my ThermApparel cooling vest (that you can’t even see in this pic) that kept me from melting entirely!” 

Nicole

“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. Discreet, effective and lightweight. Wahoo, thanks team! Now come up with cooling insert for my helmet!!!!”

Dan

“I have MS and wear it when I go running.”

“Lightweight and easy to store in freezer. I have MS and wear it when I go running - works well.

“I was able to walk much further in the heat!”

“Me and Dizzy really love our vest! It means we can now go out and about in the hot weather without worrying so much about getting too hot. And as we’re trying to be a bit more active and do more exercise, it’s also amazing for helping us to keep cool during these times too. We wore it for the first time to Hastings last weekend and had a lovely time. I was able to walk much further in the heat! We went in the shops, had a walk along the beach and even went on a little mini steam train.” 

Heather

“It’s been a total lifesaver.”

“If you are going to own just ONE thing to make your life with some ridiculous chronic illness, it must be THIS cooling vest! First of all, I can appreciate that it is not one of those bulky cooling vests that make you look like you are preparing to board a life raft. Secondly, this baby keeps me cool for up to 6 hours in the sweltering heat of Florida. It’s been a total lifesaver. It’s super comfortable, and I’m way grateful that I can wear something that is unnoticeable under my clothes and also keeps me from having a heat-related flare-up!”

Lisa Marie

“The UnderCool was a ”Godsend” for me during the recent Hurricane Irma.”

“I live in Fort Myers FL and was without power for 5 days when our community was flooded after the hurricane. The temperature was in the mid to high 90°F’s with high humidity. Not only was I not able to leave my home because of the flooding, I had no power, therefore, no A/C and no refrigerator or freezer for those 5 days. Because your cooling packs are made from the special phase change material, they did not require a freezer. I have two sets of cooling packs and was able to recharge the cooling packs by placing them with the bags of ice and the frozen water bottles I prepared. I had other water-based cooling packs that were in the freezer that had all melted. I don’t know what I would have done without your PCM cooling packs!!!”

“I can enjoy my garden again!”

“Love it! Love it! Fits great. After years of not being able to enjoy working outside with my MS, I can enjoy my garden again. Thank you.”

Happy Amazon Review

“Bought one for a friend I was so happy with this.”

“Lasted 2 plus hours, more comfy than I imagined. Not bulky. Bought one for a friend I was so happy with this!”

Terri

“UnderCool helps me keep up with my grandchildren.”

“I have been living with MS for over 20 years and I’ve worked very keep to keep it from coming between me and my family. For years we avoided traveling in the summer because I couldn’t handle the heat. I avoided other cooling vests because they were too big and bulky. The second I saw UnderCool I knew it was perfect for our next trip to Disney World! I was able to spend just as much time out in the sun as my grandkids, I love it!” 

Susan

I spend a lot more time with my horses!

“Thank you for making a great product! I have Lupus and cannot tolerate temperatures over 75°F. You’ve made it possible for me to spend a lot more time with my horses this summer.”
