The ThermApparel UnderCool Cooling Vest was designed from the ground up with help from people like you, people living with heat sensitivity. They told us they wanted a cooling vest that is: effective, comfortable, concealable, lightweight, easy to use, and helps with fatigue, cog fog, and inflammation. So that’s what we made!
