I have the Kokatat goretex drysuit with the relief zipper and I don't have to take the harness off to use it. I have used the zipper many times during the distance races. I think once even from the wire. The zipper fits behind the spreader bar and I just pull it down when I need to use it. I do like sailing in the Zhik gear better for the buoy racing. I don't feel like the Michelin Man
