UnderCool – Made for you.

Designed for heat sensitivity caused by:

  • • Multiple sclerosis (MS)
  • • Fibromyalgia
  • • POTS
  • • Lupus
  • • Hormones
  • • Other disorders

Sick of bulky cooling vests cramping your style? We get it.

That’s why we've created UnderCool, the first cooling vest to be worn under your clothes.

UnderCool cooling vests are designed to be discrete, but engineered to be cool. Four cooling pockets provide cool relief where and when you need it most. Adjustable straps and breathable, lightweight fabric keep you comfortable — no matter where life takes you.

Crave even more cool? It’s all backed by our 30-day trial period.

Hear what others have to say...

“I love how hidden it is”
Dr. Gretchen, MS Specialist
“I never thought I would wear a cooling vest and like it.”
- Meg Lewellyn, BBHWITHMS.com
“It was easy to have on for so long”
- JP Summers

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

Don’t just take our word for it...
