I think you talked me into buying a mesh jacket. I already have an evaporative vest. It was 119 degrees F. when I rode hometoday. Starting to feel a bit warm!exavid wrote:In the last few weeks I've put in over 1500 miles with a mesh jacket in hot weather... 90s to over 100. I can truthfully say that a mesh jacket is cooler than a T-shirt. It lets the air through, but it doesn't let the sun through. No sunburn, windburn, etc.I'll bet a mesh jacket would be cooler than a long sleeved shirt.
And above 100 or so I use an evaporative cooling vest... it's like having a "cold blanket" around your torso (as long as you keep moving). It works best without a windshield, but still works (to a lesser extent) with a windshield/fairing.
Mesh jackets are available for about $100 these days and you can find evap vests for $30 to $45.
And my white helmet doesn't heat up like the dark-colored ones.
It's not hard nowdays to wear protective gear and still stay relatively cool.
