For 40N+ N. Atlantic coastal offshore/short-passage sailing, I've been considering buying either a Henri Lloyd "Quest" or a Gill "Key West" foul weather jacket. Even in August, once I get a few miles out, I need to strip off my nifty Hunter-owners.com sailing windbreaker; add a layer or two; and put it back on - a pain, when single-handing.Coming back into sheltered waters, I have to reverse the process or sweat like a horse.Both of these jackets look like they'd be good for spring sailing or for my occasional forays in the rain or fog, but I don't know enough about foul weather clothing design to figure how cold it could get without my having to do the "add more layers" thing, nor how warm it had to be to make these jackets uncomfortably warm.Can anyone with direct experience with either of these products (or similar ones) in my kind of waters shed light on the subject for me?If I've chosen the right general type of jacket, is there any great difference between manufacturers?Thanks.
