I had a post for Alaska/Horizon guys about the same subject last month, and they weren't too happy about San Diego Leather.
If you want the BEST flight jacket you can get, buy one from the internationally-known Langlitz Leather in Portland OR. They have been making motorcycle leathers for about 60 years now, and make a pilot coat too. Totally tailored, unbelievable service, they will repair their own stuff for you because they built it, they know how to repair it.
On the downside, getting a pilot coat from them will cost a minimum of about $750, maybe a lot more if you want a lot of options. Not cheap. Also, they usually have at least a one month lead time to make you a jacket after you order it. Sometimes quite a bit longer. On the other hand, your coat will be as good as or better than new 20 years from now. Then you can hand it down to a relative. You can't say that about many clothes of any kind. And hey, it's part of your uniform...you can write it off!
