I had to retire my standard Roadcrafer when I moved to Florida. I went to a Roadcrafter light jacket with AD1 Light pants. I can layer up in the 40's in winter and am comfortable until the mid-high ninties. I do not find mesh gear any cooler. In fact the synthetics seem to be less breathable than gortex. I just roll down the collar, and unzip a the top and bottom with the under arm vents wide open. I lighter color helps too. I went with tan. Gives it that Carhart look.
