Looking for wetsuit recommendation for outdoor cold swimming in the pool and training for triathlon. Swimming has been my strongest part in Triathlon, but that advantage is slowly but surely disappearing as I dread training sessions for an hour were focusing on freezing takes more energy than the training itself. I am (I think) very flexible in the upper body and have tried a couple of wetsuit tops but they feel like a “prisoner’s suit” for me and did not help to keep me warm. So, what I am asking for is a wetsuit / half suit with maximum flexibility that keeps me warm for an hour plus in 18 -20 degrees Celsius. I don’t have a specific budget, but around $500, - plus /minus. Thanks & Regards, Hfareast25
