Vanson is one of the major leather jacket manufacturers here in the US and often considered one of the best to get. They are extremely well made. http://www.newenough.com is a good place to get them and they have great service and will help you get the right fit.
Look on their website's product page and it will give you a lot of info about fitting. They are generally cut for the bigger torso type builds.
Yep, I love mine. I went for a custom fitted 1-piece. US$1,700 Just downloaded the form and gave them all the measurements. Only thing is if you're going to wear a separate back protector, make sure you're wearing it when you measure yourself. The included one isn't the best in my opinion although I use it since I didn't allow for it when I was measured.
Be patient. This is an EXTREMELY busy time for them. The Racing season is just beginning here in the US so they are trying to get repairs done and new suits made for various racers across the country. Give them a few weeks to settle down.
