Where in the hell can you find them? Not seeing much, I'm 6'3 280 lbs.....
Aerostich has good but pricey stuff too. Have you tried Joe Rocket?Fox creek makes very nice stuff and to your specs. Bit pricey but, fine made in USA stuff. I wear 'tall' and have a jacket from them thats been through hell and still great shape. I do service it occasionally with good dressing. Other than that find out where the motor cops (if any) near you buy there gear and try that. Any city that's got cycle cops has a good decent leather shop.
