Susan's story

How UnderCool helped a grandmother
spend more time with her family.

"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!"
