I wear scorpion cool rod mesh jacket (last years model) and scorpion duece pants (mesh). Held air gloves. Icon field armor boots. Some cheap full face helmet.
I avoid traffic in the summer. Above 95 or so, I am hot no matter what my speed, and peeling off that mesh gear does not help. I actually got chap from flapping shirt in the wind without the mesh jacket last summer. So I just wear the mesh, always.
Make sure you drink enough water so that you can piss, and it is not dark yellow piss.
