Every BODY is different...
Thanks for the feedback. Let me see if I can summarize what I've learned so far;
For ARID conditions, a cooling vest and stay hydrated. Most favor a mesh jacket but others are saying that when ambient temp is above body temp then a closed up jacket might work better to keep the heat out and the cool in.
For HUMID conditions, no cooling vest, stay hydrated and wear well-ventilated clothing to keep the air flowing over the skin to enhance the evaporative effect.
In all situations, protection from the sun's rays on the skin is essential. Is that about it?
No. There is no cut and dry solution to riding in the heat. Every
Body is different.
I like the heat. Don't take the liners out of my jacket till it reaches 80. The heat starts to affect me at 105. Hubby starts to have heat problems at 95.
Case in point... In July we decided to make a cracklin run from Houston to Scott, Louisiana. One day down, one day back. We were on the way back and stopped at Don's Meat Market for cracklins and boudin. Yum, big biker stop.
We met a biker who had red hair and fair skin bundled up, including a wet towel around his neck. Turns out he can't handle heat and has a cooling system on the back of his bike. He loves to ride, but can't handle the heat, so he figured out a way to be comfortable and safe.
On the way home, Hubby got heat stupid at 98 degrees. I pulled him over and made him drink sea salt water, waited till he was better, then rode home.
#1. They talk about hydrating, but don't talk about replenishing the electrolytes leached by sweating. Like someone said, Pedialyite has less sugar than Gatorade, but I prefer putting sea salt in my water. Cheaper, but still does the job.
#2. The older you get, the less you can tolerate heat.
#3. Most important! You are talking with people from all different climates. Between different body needs and acclimation to different temperatures, you are going to get answers all over the board. You need to find out what works for you! Nobody else can tell you that.
There is no cut and dry solution....
