Shopping Cart [Even though they don't feel cold, they are still working. If your ThermApparel Cooling Packs are still in a semi-solid state (meaning you can’t see through the entire pack), they are still pulling heat from your core and cooling you down. Feel the skin on your back. Is it cold? If not you might have the wrong size and need to do an exchange.
The main reason why your vest may not feel "cold" is because ThermApparel Cooling Packs melt and freeze at 70°F/21°C. Example: Think of jumping in a swimming pool with a water temperature of 70°F/21°C. At first, it will be frigid, but after swimming for a little while, your body will adjust, and it doesn't feel as cold, but the water temperature has not changed. It has to do with the amount of coolness. Think of washing your hands in water at 70°F/21°C. Now think of taking a shower with water at 70°F/21°C. Burr!
Try doing the same activities with and without your ThermApparel UnderCoolCooling Vest and take notice of the differences. Compare your fatigue and cog fog levels. After you take the vest off, touch your back. Is it cool? Does the cooling effect last a while even though you are not wearing the vest?
Our ThermApparel cooling vests will cool down your internal body temperatures without constricting your blood vessels or burning your skin, making for a full range of movement and more energy to spend on the things that you love.
It's not about feeling cold, it's about feeling good.
