The document summarizes heat and ballistic testing done on the TacVent, a passive ventilation device for body armor. In a heat test, the TacVent lowered temperatures by over 17 degrees compared to armor without it. A ballistics test found that the TacVent reduced trauma from bullet impacts by decreasing back deformation of the armor and reducing cratering of clay behind it by over 50%. The document concludes the TacVent is the only effective solution for body armor ventilation.

1. THE ONLY SOLUTION IN BODY ARMOR VENTILATION
We thank you for taking the time to look at the cop-invented and American-made TacVent, the first and
only passive ventilation device that allows the unobstructed flow and release of heat through true
separation, using actual space, not matter – no spongy, meshy, absorptive material or inflatable devices,
both of which can be counterproductive. TacVent is a distinctly unique and patented design consisting of
a corrugated and perforated panel of soft, engineering-grade, hypoallergenic thermoplastic elastomer.
Below is some basic information on heat and ballistic testing that was done to illustrate TacVent’s
unmatched ability to passively ventilate under-armor body heat, as well as its profound potential in
trauma attenuation.
Our “scientific method” is truly as spartan as it gets, sparing not merely in expense but in distraction,
adhering to the principle that maintaining only one variable produces purely objective results.
Pictured here is the astonishing result of our heat test. All items used were identical, including 2
mannequins, 2 panels of level II Kevlar, 2 heat pads, 2 T-shirts, and 2 electronic thermometers wired to a
sensor at the center of
and behind the Kevlar,
between the carrier and
mannequin. Again, the
single variable here was a
TacVent, placed between
the carrier and T-shirt on
one of the mannequins,
pictured on the left side.
Whereas similar tests
have resulted in a
difference of quite an
impressive 14.5 degrees,
this test produced an
astounding 17.2 degree variance. Notably, cool-down to room temperature was achieved far more
quickly with TacVent when heat pads were turned off. (Please visit tacvent.com for a video of this
experiment being conducted.)

2. Next and equally extraordinary is TacVent’s ballistic test, trauma attenuation being an ancillary benefit
as ventilation was initially our sole intended purpose. As with the heat test, all items were identical with
only one variable, a
TacVent. Other items used
were 1 “Century Bob”
heavy punching dummy, 2
quantities of 10 pounds of
clay, 2 cotton T-shirts, 2
level II Kevlar vest panels, 2
rounds of FMJ .45 ammo,
and 2 rounds of FMJ 9mm
ammo, each fired from 10
yards at the left and right
side of “Bob” for each test,
respectively.
In the first ballistic trauma test, ABOVE, performed without a TacVent, profound damage was done not
only to the clay, cratering 4” wide and 3” deep with both calibers, thoroughly reaching Bob’s surface,
but back-face deformation was massive, ballooning the Kevlar fibers and causing significant tearing of
the carrier, ominously indicative of what might happen to a user if shot.
In the second test, BELOW, performed with a TacVent, the results were phenomenal. Back-face
deformation of the Kevlar was virtually nonexistent, and cratering was reduced by at least 50%, roughly
2” wide and 1”
deep with .45
ammo, and 1.5”
wide and less than
1” deep with 9mm.
This would certainly
address and
eliminate any
concerns as to
whether or not the
½” of space created
by TacVent would
diminish the
ballistic capabilities
of Kevlar, in fact
ostensibly improving it, as well as clearly and dramatically reducing blunt force trauma. (Of course, as
with the heat ventilation test, please visit tacvent.com for a video of the ballistic trauma test.)
Again, we truly appreciate your time and consideration, hoping you will join thousands of law
enforcement, military, security, EMS and others in choosing TacVent as the only solution in body armor
ventilation.
Sincerely,
Jeff Shelton
