If you’ve ever owned a car that doesn’t have air conditioning, you know that wonderful feeling of sitting in the middle of traffic sweating through your clothes. Without that wonderful component of your car, there’s really no good way to keep cool when stuck in traffic. That is unless you had one of these shirts.

If you’ve ever installed a liquid cooling system in a computer, you’ll be familiar with this concept. The tubes you see carry cooled water all over your chest and back, thus cooling you down without getting you wet. You’ll need to hook the tubes up to a pump that pulls water from a cooler in your car. Sure, this doesn’t seem very logical for most people to have, but it’s great for professional racers who spend long hours in hot cars.
