TacVent: Cooling System

The TacVent is a simple, inexpensive, and functional way to make wearing body armor more comfortable.

Jeff Shelton says throughout much of his law enforcement career he wouldn't wear body armor for the same reason that many officers refuse to wear their vests, heat and discomfort.

Then came Nov. 1, 2013. Shelton, a sergeant with a Southern California law enforcement agency, was training that morning when a man started shooting people with an AR-15 in Terminal 3 of Los Angeles International Airport. Arriving at the airport, Shelton decided to wear his tactical body armor with the ceramic plates. After all, even though one suspect was wounded and in custody, there were reports of another.

For much of the rest of the day, Shelton sweated in his heavy tac vest, as he and his fellow officers searched inside and outside of LAX for a ghost. But the fact the second shooter didn't exist didn't make the work any less hot or arduous. The experience made Shelton reconsider an idea for a body armor cooling solution he had mulled over years ago.

Shelton's idea was to find a way to allow air to pass between the vest and the wearer's shirt or undershirt. "The only way to allow ventilation between the officer and the vest is through separation," Shelton says.

Of course, if you separate the vest too far from the wearer, you can make it impractical to wear. Shelton reasoned that one-half inch of separation would provide enough ventilation to cool the officer while not making the vest difficult to wear.

He then decided that a corrugated system kind of like a radiator that attaches to the armor carrier was the best way to achieve that ventilation. Next he needed to determine the best material for making the ribbing. "I knew it had to be soft and rubbery and not be something that would stick into the wearer or cause pressure points," he says.

With the first TacVent in hand, Shelton needed a test subject. So he wore it on duty. He found that the separation of the vest from his undershirt made a big difference and actually improved the wicking and evaporation capabilities of the shirt's fabric. He says the TacVent keeps the wearer up to 14.6 degrees cooler.

In addition to wear testing, Shelton knew he had to test how the TacVent affected the ballistic protection of a vest. So he devised his own method to do so. He spread ballistic clay two inches thick on a heavy punching bag and placed a t-shirt over the clay and then an NIJ Level II vest over the shirt. He shot the vest that didn't have the TacVent with a .45 ACP ball round and took measurements on how deep the round pushed the fabric of the vest into the clay. Then he used a TacVent-equipped vest to repeat the test at the same distance. "With the TacVent, there was only a slight dent in the clay. Without it the backface trauma pushed all the way through the clay and into the punching bag," Shelton says, adding that he believes the TacVent reduces trauma by as much as 50%.

The TacVent is U.S. made and sells primarily online at The price is one for $34.99 or two for $59.98. Shelton recommends a front and back application for concealed body armor.

Shelton says he is a user of his own product, and he is now a conscientious wearer of body armor. "Now that I have the TacVent, I don't have that feeling of wanting to rip the vest off all the time," he says.

I spent $60 for this thing from their website and I am not impressed. It's basically a piece of rubber that actually makes the parts of your body it touches warmer. True, some air comes in and out of the top, but it's coming in and out of a big space where a bullet came come right back in. And the hot parts of the thing just balance out the cooler parts of the thing making the temperature thing a wash. After trying my vest with and without it over and over I determined my vest just works and feels better without it.

I agree that it doesn't really work. It actually made me less comfortable, between being hot, being poked and cut into, it shifting around, etc. I never thought about the space it makes where a bullet can get into your vest. That just makes it even worse. Putting a big piece of vinyl siding into my vest just didn't work for me.
