wet suits/float tubes

I love fishing in my float tube, but unfortunately the water starts to get a little rough on certain areas of the anatomy this time of year. Has anyone ever used a wetsuit/diving suit during the colder months? Are they warm enough for a full day of "tubing"?

Any help is appreciated

Get some good Cabelas Neoprene waders and layer under them....I strongly suggest the "Under Armor" stuff when it gets real cold.

Works like a charm.
