I use a Yanagawa rep Texport suit - more perforations than a tea bag and cool, cooling carbon fibre ducts in the shoulders that blast cold air down my back (at strictly legal speeds - honestly).
Only drawback is it only has one pocket that, when I cram it full of keys, smokes, phone, lighter and wallet...makes me look like I have one breast. If their jackets are as good as their suits then they are definitely worth a try.
I never feel safe with just a jacket. But that's just me.
I did used to use a Dianese jacket and strides, err pants, years ago - bit pricey but good gear + I found the fit a bit better suited to me than a lot of the others.
I don't know if you can get Heine Gericke stuff in the US, their stuff is good and cheaper than some too.
A ROTM winner yes, really! Blame bungles & WillZX14
