Postby gompa » Tue Jun 21, 2011 4:21 pm

I live in Las Vegas area, and as everyone knows it get mighty darn hot here in the summer time. and just wearing a pair of levys, just dont work all that well to keep cool.
My wife and i will be taking a very long trip next month and expect to run in all kind of weather and what i am asking for opion on leather riding gear, during the summer month as well in the rain. beside of the protection we will have from the road, how does it work in the hot summer, will we be hotter wearing them.
right now we cant aford a nice pair of cool suit that i have seen advertised , and my wife wants.

thanks for any info

Leather is expensive!

I can't say enough for the mesh gear that I have. Jacket and pants, they have armor and protection where you need it, and mesh that lets air flow through where you don't.

That said, I've spent weeks at a time working in Las Vegas at all times of the year, and as you know, in summer the heat is unbelievable - so hot, that mesh gear will actually make you HOTTER.

This is an article I had saved on my computer a couple years ago, that explains why mesh gear doesn't work in desert heat:

Why Mesh Riding Suits Don't Work in Extreme Conditions

Human bodies exchange heat with their surroundings in four primary ways: convection, conduction, radiation, and evaporative cooling (from perspiration). When ambient temperatures are below the body's normal temperature of 98.6°F, all of these pathways can provide cooling. The higher the windspeed, the more cooling there is from convection. But when ambient temperatures rise above 98.6°F, only evaporative cooling can work. More importantly, too much wind becomes a bad thing. There is a limit to our body's perspiration rate and when the wind speed uses up all of the available perspiration, more wind increases convective HEATING. This is the opposite of "Wind Chill". I found an interesting article on this effect at:


What this means is that you do NOT want to maximize the wind against your skin when the temperature gets extreme. Mesh suits, or wearing just a lightweight shirt, are NOT the right approach. You will actually stay cooler with a conventional suit with the vents adjusted so there is a more moderate air flow across your skin.

You Have to Carry Much More Water to Ride in 110°F+ Temperatures

When temperatures are below 98.6°F, you may perspire less than 1 quart per day. But when the need for evaporative cooling kicks in, you perspiration rate can increase to 1.5 quarts PER HOUR. If you aren't drinking 1.5 quarts per hour under extreme conditions, you will start becoming dehydrated. Your perspiration rate will decrease, you will feel hotter, your heart rate will increase, and your judgement will start to become clouded. If you are a competitive endurance rider, you can probably go at least 300 miles without stopping. If you are averaging 75 mph, that's four hours. You may need to consume 6 quarts of water in that period of time when the temperature exceeds 110°F.

I carry an insulated 1-gallon cooler with a drinking tube attached when I know I will be riding long distances in hot weather. It was barely adequate for this trip because I deviated from my normal routine and purchased an extra bottle of water to drink during my fuel stops. On one leg, I made the mistake of starting with less than a full gallon and started experiencing the early signs of heat exhaustion. I felt much better after sitting in the shade for 10 minutes while consuming a full litre of bottled water.

Based on my personal experience and research, there is a world of difference between 100-105°F and 115°F in terms of how much water you need. A half quart per hour is more typical of what's required near 100°F. You might even be able to to run without water for several hours at about 100°F and make up the deficit by drinking at lot at your next fuel stop. But at 115°F, the level of dehydration you will be experiencing between fuel stops is excessive; you will definitely experience heat exhaustion and possibly heat stroke.
Why You Might Not Want to Be Wearing Shorts Under Your Riding Suit

Some popular bikes have "issues" with high levels of engine heat. My K1200GT makes the lower half of my legs warmer than on my K1200LT, but it's never been a problem for me, until this trip. Air passing through the radiator on both the LT and GT exits at the side of the fairing just in front of the rider's legs. On the LT, the hot air is blown far enough away from the bike that it does not impinge on the rider's legs. On the GT, the fairing is not quite as wide and you can feel heat from the radiator on your lower legs. The heat I feel on the GT is clearly less that the heat I've felt riding other bikes, such as the FJR1300. But on this trip, the heat became a problem. I rode for a long stretch with a slight crosswind which increased the amount of radiator discharge that impinged on my right leg. It got very uncomfortable. When I stopped for the night, I discovered that I had second degree burns on the back of my right calf.

This wouldn't have happened if I had been wearing long pants under my Aerostich. Under identical conditions, I did not get burned wearing blue jeans under the riding suit.

This problem showed up for the first time because the radiator discharge temperature is directly related to the ambient temperature. Although engines run hotter in hot weather, they actually discharge about the same amount of heat energy into the radiator. That heat energy raises the temperature of the radiator discharge the same amount that it does at lower ambient temperatures. At 100°F, the radiator discharge might be 140°F and it might get knocked down to 110°F before it impinges your leg. It feels very warm, but it won't burn you. If the ambient is 15°F higher, you leg might be exposed to 125°F and you can eventually get burned if your leg isn't insultated from the radiator discharge.

According to data from the National Burn Center, the time at temperature to cause a second degree burn is as follows:

113°F 1.7 hours
122°F 2 minutes
131°F 11 seconds
140°F 2 seconds

The only thing protecting you from being burned when your bare skin is exposed to ambient temperature of 113°F or higher is evaporative cooling and the cooling of the skin surface by blood flow. To be protected from radiator discharge temperatures in excess of 113°F, you need INSULATION between your skin and the hot air stream. What I painfully discovered is that the insulation provided by an Aerostich suit is not enough.

Thank you for the great information, now i know why mesh suit only work in the 90s but not so well in the 100s, i agree with you about drinking alot of water, we make sure we stop for at least 15 min every 200 mile, and drink water. and leave the coffee and soda alone.
maybe leather might be better after all, sound like it works the same way way as my wet suit when i scuba diving..
