I wear an Aerostich Roadcrafter most of the time. With the electric liner it is good down to about 40 degrees. Above 85 or so I switch over to a padded mesh jacket and padded denim. I have a First Gear mesh that has excellent air flow but does not provide anywhere near the protection of the RC. I also have a Darien jacket and insulated pants for temps below 40. Don’t get many opportunities to use them here in Texas, and for the most part we can ride year-round with the right gear.
