Since switching to a drysuit... close to two years now, I have only been in a wetsuit once, and don't really plan on going back (unless somewhere tropical ), but I would wear a bathing suit underneath. Under my drysuit, I wear the Fourth Element Arctics, as well as a 200g fleece over top during the winter, and 400g DUI booties over my Thinsulate socks. This is what I use for winter diving, but would prefer that I had a Bare CT200 over top of the Arctics. During the summer, I wore the Arctics, as I had a leaky drysuit, and they were perfect. Now that I actually have a dry drysuit, I'll see what happens this summer.
