Like @MS said, I wore my suit the last couple weeks of our season. The last time, I was in and out of the water for 30 mins or so pulling the course. Water was low 40s. Hands and feet were cold, but drysuit was warm. That day, I wore my Elite vest underneath for a bit more warmth and my core was sweaty. I love that suit. Absolutely recommended if a drysuit is what you're after.
