How to Wear
Sick of bulky cooling vests cramping your style? We get it.
Just because you want to be cool and comfortable doesn't mean you have to sacrifice your appearance. That's why we designed UnderCool to be worn under your clothes. You can wear virtually anything over the UnderCool and no one will be able to tell you're wearing a cooling vest!
UnderCool features adjustable straps and velcro on the front to effortlessly fit a wide variety of shapes and sizes. Four cooling pockets along the back provide cooling relief where you need it the most.
Remember, stay cool!
