Most of the time I was dressed in short t-shirt and airglide mesh jacket. Kevlar jeans and full face helmet. Under I had on Under Armour moisture wicking shorts. I always started out with a good dose of anti monkey butt powder.
I started out with beaded seat cover which I soon took off. The seat I have (Russell) was comfortable without. Under the seat I made a insert of heat barrier padding that kept the seat from getting hot.
I have the wind deflectors and sealed the side covers with the 2008 covers so my legs did not get the engine heat either.
When the temp started getting hot 90 up I put on my cool vest that I kept in cool water in a zip lock bag. The vest was of the greatest help,remarkably cool. At every stop about 120 miles I drank a bottle of water. On my bike I have a drink caddy that I sipped water as needed. I was remarkably comfortable the whole ride.
Kept sunscreen on at all times. Hat when not on the bike.
I felt a little odd duck as I was the only sport touring rider, most others where half helmet , no jacket short shirt riders. ATGATT was not in their philosophy. Lets say the jacket on all the time had them concerned. But those that have the airglide jacket we attest that the jacket is very well ventilated. And the pads on the back and shoulders keep the heat off your body.
