I have one, too. Great vest.
One thing to watch for: when they say size Large, they mean large. I have kind of an in-between size build. I can usually wear a medium or a large and get by o.k. Not so with Filson. I ordered a wool shirt and the vest, and both were way too big for me. I gave the shirt to my brother, and got some clipon elastic dohickies for the back to give me a nice fit. Should have sent them back for mediums, but I figured I might grow a bit during my aging and it would fit fine. Hasn't happened so far, knock on wood!
