Oops. Must have been reading your post late at night.

Two piece wetsuits are easier to find than two piece drysuits. There is another type of insulation that you might want to consider. Known by a variety of names including "fuzzy rubber", "hydroskin", etc. it combines a waterproof, breathable outer fabric with a fleece-like inner fabric. For anyone who has spent much time in a wetsuit, you'll appreciate the comfort of this new fabric. It's great for activities where you're not continually immersed in the water, but rather have concerns about evaporative cooling, etc. I love the stuff. I often wear my fuzzy rubber top combined with a farmer john wetsuit for cool Vermont sailing.
