My wife has been certified since before me (back to the 80's) but she can't get in the water anymore because she's too cold. Granted, she's anemic because of chemotherapy destroying her body's ability to make red blood cells but she's always been a bit anemic even before that. I bought her a 5/4 full wetsuit but she's still reluctant. Anybody tried a heated wetsuit?
