"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!”
