Fully-armored textile is a great way to go. As long as you are moving you are getting airflow. When sitting in stopped traffic not much helps. If it's searing temperatures you can get a cool vest to wear under your jacket and it really cools the body down.
Isn't it nice that we can think about these kinds of things while others are looking for their thermal longjohns?
Geeez, how soon is soon?
We sell a lot of the Joe Rocket Phoenix 4.0 mesh jacket. Large hole mesh design, still fully armored and a removable liner. Comes in a lot of different colors too
