I measured my entire body about 10 times, much to my wife's annoyance, and when I got it I struggled for half an hour to get it on and an hour to get it off! I panicked I had gotten the wrong size as it felt really tight! Then I wore it windsurfing a couple of times and realised it is a super comfy suit, fits and I can now get in and out of it in 5 minutes 😆 I felt warm in 6 degree water and similar air temperatures and didn't feel any restrictions windsurfing. The jersey material seems to bobble, but that could be because my board is really grippy and I was pulling my self up rather than water starting. I haven't had a similar suit, so I can't compare, but very happu with it. I bought this brand because my size seems to be out of stock everywhere with all the more mainstream bigger brands. Glad I bought it and highly recommend
