that I've used once. I bought it for some Newfoundland sailing on the recommendation of a guy who was a commercial diver and did a lot of work in the North Sea. I just took his word on it, and, other than being a bit much for practically all my sailing, I haven't had any complaints about it. Workmanship is fine.

The time I used it, the weather was in the 40's and it was raining. Thing kept me warm and made the day comfy! That's one of only two times in the past few years that I've been out that it has been cold enough to consider wearing it, though. Put on when it is too warm (tried that once) and you end up having to dog-paddle in your own perspiration!
