I have a Sterlingwear of Boston pea coat which has lasted me over 20 years and counting. I believe I have the Navigator in black, which is 24 oz 100% wool. It's wind proof, warm, and basically water proof. I've been in the rain with it a ton and it never seeps. I have a new puffer jacket I love, but it doesn't resist water nearly as well and runs a little hotter because it's not a breathable.

The only pea coat I've found which compares is the Schott in, I think, style 782USA, but it's about twice as much, but it could be the less expensive style 740. Both are 32 oz wool. The Sterlingwear Classic is in 32 oz too.
