How Do You Wear A Cooling Vest Like UnderCool?

Most cooling vests on the market come in a few sizes and are meant to be worn over your t-shirt. Since the majority of cooling vests are ice and gel based the t-shirt is very important to keep your skin from getting ice burns or wet from condensation.

ThermApparel's UnderCool Cooling Vest is designed with discretion in mind with it's low profile design. UnderCool is meant to be worn under your clothing safely next to your skin.

UnderCool is easy to wear. First make sure the packs are charged and ready to go, if not fold the vest and place it in the freezer for 40 min, fridge for 60 min or pull the cooling packs out of the vest and lay them flat in ice water for 20 min.

UnderCool is a unisex garment that comes in 5 sizes XS, S, M, L, XL. (Please refer to our sizing guide here for more information.) The garment has adjustable straps and velcro across the front to accommodate the waist of any user.

UnderCool can be worn both under and over clothing, according to your preference. We recommend wearing it under your clothes for maximum cooling effect. No undershirt required.

Our cooling packs melt and refreeze at room temperature, keeping your skin safe and cool at the same time.
