Just an update to this thread.
I bought my Fieldsheer Carbon Race jacket from
Moto Liberity maybe a month ago for $200 and have worn it maybe a dozen times from 75° night weather to 95° sweltering afternoon heat and it's not to bad as long as I don't get stuck in traffic for to long. I've actually rode in bumper to bumper traffic for 15 minutes or so and it wasn't bad at all.
Looks like my mesh jacket is going to the back of my closet
