How to Reduce Heat Exhaustion on Motorcycles by Improving Your Ventz

A sure trait of a motorcyclist is the inclination to take something perfectly functional, and tear it to pieces. We’re tinkerers. We say things like “It’s a known fact the manufacturers put entirely too many screws, nuts, and bolts into our motorcycles.” We tell ourselves these lies to cover up for the fact that we just spent two hours rebuilding something and haven’t the slightest clue where the leftover pieces were meant to go.

Motorcyclists travel the roads less taken. We often go against the grain. OK. We usually go against the grain. The fact is that our ingenuity combined with a lot of elbow grease often produce creations we would never have otherwise seen. Think of choppers, bobbers, and cafe racers. In the spirit of motorcycling I decided to take my Ventz, tear them apart, cut pieces out of them, and put them back together. The goal was to create a cooler, better-than-factory motorcycle jacket ventilation device. Mission accomplished.

Here’s a little more history for you. In another life I was a first aid instructor. It was a great job. Classes were taught pool side, in and out of the water so I didn’t have to wear much in the way of clothes. To make things even better, everyone on staff was young and fit. Sometimes I wish I had that job!

Back then we taught lessons on heat and cold. We lectured on the places where people lose the most body heat – your head, your neck, your armpits, your groin, behind your knees – these were important places to keep warm in the event of hypothermia. We also taught the treatment of hyperthermia (elevated body temperature). The Ventz attempt to reduce the risk of hyperthermia and heat stroke to motorcyclists by circulating air up jacket sleeves in order to cool arms and lower your core temperature. You can read our full Ventz review here.

As a rule of thumb, one of the fastest ways to cool down your core temperature is by cooling anywhere you have a pulse. Think about how effectively running cold water on your wrists cools you down in just a few seconds. You have your brachial and radial arteries to thank for that. Think about how effective a cool damp cloth across your forehead or neck can be. You have your temple and carotid pulses to thank for that.

Heat can be much more of a problem for motorcyclists than just a matter of physical discomfort. Heat stroke can bring on dizziness, light-headedness, weakness, cramps, nausea, confusion, disorientation. It can even bring on seizures and knock you out. To make matters worse, heat stroke sneaks up on motorcyclists. Motorcyclists can keep bring their core temperature down the fastest by exposing the places they lose the most heat from to elements of coolness such as water or air.

Ventz is a good product that helps motorcyclists to get some extra airflow up their jacket sleeves, but it has on design flaw. The Ventz cover your wrists. They thereby cover your radial pulse. That means less heat escaping your body which translates into a higher core temperature. Sure, the Ventz get air blowing along your arm which could cool the rest of your brachial vein, but why go the long way around?

Here’s how I modified my Ventz to further reduce heat exhaustion and keep my body temperature cooler when out on long motorcycle rides:

1) Bought some Ventz – Check them out at You can also read our Ventz review (I’m almost done linking to it, I promise).

2) Grabbed a straight edge razor – On occasion I like to assert my old school manliness by lathering up and shaving with a straight edge razor, barbershop style, minus the old guy and the spinny hydraulic chair. I used the razor blade to slice into the existing grooves of the underside of the Ventz and across the top. 9 cuts in total.

3) I ran with scissors – Fact: Every true bad ass writes on the internet about how hardcore he is. I recommend using scissors for the final cut. You don’t want to apply so much pressure as to break the Ventz into two pieces. They are a serious pain in the butt to push back into place. use scissors rather than trying to do everything with a razor. It’ll save you time in the long run.

That’s it. I know have Ventz which not only direct air up my sleeves, but they also pass air over my radial pulse, which is where I feel I need it most. The modification cost $0.00 and I do feel the difference.

My recommendation to the Ventz guys: Hurry up and patent my design before I call up the factory and China and have them start making these puppies for me to sell myself! Feel free to send me some royalties!

If you have a pair of Ventz, like my idea, have any questions, or if you enjoy tinkering and running with scissors as much as I do, please leave a comment! Don’t forget, sharing is caring, we’d appreciate a little social media love!
