Seeking to replace jacket that I don't know how to call
First of all, I'm a long time lurker and have learned a lot through these forums. I registered because I'm looking to replace an old jacket I've had for about six years and don't know how to describe it. Its duck canvas and, importantly, has a knit neck (I've heard it referred to as a "scuba neck") and knit arm cuffs. It has a "slim" fit but not super tight. I guess it reminds me of some kind of "tanker jacket" but the ones I see online seem like they marshmallow out at the body, and don't hug the body. Can somebody help me with identifying what kind it is and where I could buy something as similar as possible online?
