I'm a pool swimmer who just started doing some open water swims this year along with some triathlons. I rented a wetsuit for one of my races this summer because the water was chilly. I swam pretty slow and I'm convinced the wetsuit was a big reason for my lousy swim. I felt like my lower body was floating/bobbing in the water and it prevented me from being able to rotate my body properly...I felt really bad in the water. I was wondering if perhps it was the brand of wetsuit I used (2XU). Does anyone know of a wetsuit that would keep me warm but not have the same negative effect on my stroke?
