I bought this for swimming in the north (northern Canada) where the lake here in August is a bit chilly for my liking. I wore it scuba diving with a spring suit on top. I've only worn it once but I'll say that the seals are very good so far! The fabric is flexible and easy to move in. The body is a bit looser than I expected but it's not huge. I probably could've sized down and it would've fit better, especially in the height/length.
