Haven't heard that one before. How does that work?
EXCELLENT post.
Note that too much salt in your water might make you throw up.......thus making matters worse. :shocked:
Shouldn't it have been: "To whom, are you addressing that comment?" :dontknow:
At least you didn't have to press "1" for English
Vents open or closed. Depends on how hot it is. At 96 degrees the outside temperature is still cooler than your body temperature so in that case vents open and or mesh jacket and a cooling vest is really great to have. This is what we use https://www.revzilla.com/motorcycle/revit-liquid-cooling-vest. I do find that it lasts longer if I don't wear the mesh jacket, but use my 4 season Jacket with vents open. Either way you can recharge them when you stop to get gas by soaking them again.
This summer we have done a lot of ryding in 105 to 106 degrees. Now science tell us that heat will always transfer from the hotter surface to the cooler surface. The laws of equilibrium tell us that if it is 106 outside and you are at 98.6, you want to keep that hot air out. This is where you would want to close vents (and yes even in your helmet) and keep the cooler 98.6 on the inside and the 106 on the outside. You will sweat, but that sweat will last longer and cool you longer if you can keep it from evaporating too quickly. You will still receive some benefit from the cooling vest in these conditions. A couple of reasons why the heat has a greater effect on your wife would be that she is probably smaller than you, so less surface area for the sweat to cool her, and her pores are smaller than yours and she just doesn't sweat as efficiently as you do. I have ryden in 106 for 4 hours completely closed up and kept pretty cool. Certainly I had no symptoms of heat sickness at all. Oh and drink at least a liter of water ( and only water ) for every hour on the road.
So key temperature is 99 degrees, below that temp open up ( but keep fully covered no tank tops, flip flops, cutoffs etc. Above 99 close up and lock in that cool 98.6. BTW if you are just taking a quick jaunt to the grocery store.........wear whatever you want!

If it is over 99 degrees outside, you want to keep your 98.6 inside and away from the 102 outside. You will remain cooler by zipping up all vents and even closing the vents on your helmet. Keep the 98.6 inside and you will be cooler. I tested this coming home from Valcourt. Drove 200 miles across South Dakota in 102 degrees. I closed up everything and remained cool throughout. Once you jump out there in your shorts you will dehydrate and go into heat sickness very fast. So if you are going to the grocery store you can wear what you want, but for me, I am going to remain covered like those cool, calm collected BMW ryders.....and the long, tall cool one....Ann Myers!
I'd sure like to pursue this topic a little more. My wife and I took a ride yesterday in 96 degree weather. She was wearing her First Gear Hypertex jacket and I was wearing my mid-weight Olympia jacket with the pocket vents open. We both have HJC IS MAX-II modular helmets with the vents open. I was pretty warm but not dangerously uncomfortable but Jane was miserably hot.
So, I'm looking into this again, because living in Utah, hot weather riding is a reality and for safety sake if nothing else it's important that we not get overheated when riding.
So, vents open or closed?
Dedicated hot-weather mesh jackets or not?
High tech evaporative vests with built-in water supply worth the money and bulk?
Thanks.

Table salt is sodium. Nothing else. I agree, too much salt/sodium is not good for you.
You want your sweat to evaporate as quickly as possible.
My wife and I use full mesh jackets with armor in the key areas, and combine that with cooling vests, which are a quilted vest that is made to soak up a lot of water. We have ridden in 100+ degree weather for hours at a time and kept cool enough to keep riding. or last big ride of 2,600 miles in nine days found us in Hell's Canyon at 104 degrees and we managed alright. I don't enjoy riding in that kind of temperatures but with the cooling vest we can. They last about two hours until we need to re-soak them down.
