+1 for Olympia's AST... great jacket in cool weather, I haven't tried it in warm weather yet. It has a lot of utility for different riding conditions.
What kind of budget are you working with? When I got back into MC's a few years ago, I had a very limited budget. Plus, I didn't know my ass from my elbow as far as what constituted good gear, or what I was in the market for. This is actually what first brought me to Advrider... I bought a cheap jacket (from motorcyclegear.com) and it was pretty decent for my first year, but I was soon looking for some improvements.
. I would encourage you to look into a price range of up to $350ish for a jacket if buying new...but heck, use the flea market here on ADV!
