Even though it’s winter, I’m going to switch gears for a second and talk about undershirts designed to keep you cool.
As you’ve likely seen, I’ve written about cooling apparel before, including about other cooling shirts.
The common theme with those other shirts is that they have to be worn by themselves as outer cooling shirts for them to be effective.
The list below expands on that concept, allowing the wearer to sport these hi-tech cooling shirts as their under/base layer.
Since primarily used in sports scenarios where individuals can easily overheat, most of shirts in the list below use some sort of cooling mechanism.
You’ll see what I mean below.
Be sure to check out my Top 4 Cooling Apparel Categories article if you’d like to learn about what cooling technologies are available.
If you’re looking for cool, lightweight daily-wear undershirts, check out my Thin Cool Undershirts article.
Here’s the email the triggered all the research and discovery:
I am looking for something like this Ultra Cool RVU Undershirt.
Basically we are looking for a way to keep the drivers cool during the race.
I also saw this website called cooling shirts and their products would be great. But, I think is gonna cost too much.
Our budget is about 230 euros for each suit.
If you know something more about it please contact me!
Thank you Tug!
Cooling Shirts / Cooling Undershirts / Cooling Vests
The RVU undershirt is no longer being made, however, I do have contact information for the inventor who could let me know if she has any remaining inventory.
Though, the RVU does not have any actual cooling channels that allow a coolant-like substance (i.e. cold water) to be sent through the shirt.
The RVU is actually made from a Coolmax moisture wicking mesh fabric and uses the baffles in the shirt to keep the outer/over shirt from coming directly in contact with the full torso.
By allowing for that gap between the undershirt shirt and over shirt, it creates air channels that aid in sweat dispersion/evaporation — keeping the wearer cooler.
i suppose if you determined that the RVU undershirt really worked for your purpose, and you couldn’t get any more of them, we could find you a manufacturer or a seamstress that could make something similar for you.
In addition to the RVU, there are some other potential options:
CoolShield Vented T-Shirt
Very similar to the RVU undershirt, but with fewer channels.

Columbia Omni Freeze Zero
The makers of the Omni Freeze Zero state that their technology can cool the wearer down up to 10 degrees. Though, I don’t think it works as effectively if worn as a base layer underneath a bunch of other gear. I think it has to be worn on its own.
This cooling shirt uses Polyvinyl Alcohol disks, a state-of-the-art synthetic material, that absorb water. When air passes over the disks, it creates a cooling effect.
From my experience with the product, I think it also has to worn alone, and not as an undershirt.
