Reasonably happy. They don't seem to fit quite as tight as my Speedos, so that 35' waist would probably be ideal compared to 36 which I wear, but of course you can't get that size. There was a moment yesterday when I pushed off from the side where the suit seem to slip a bit down my bottom. I waited till I reached the other side before I did an adjustment, and they were fine after that. Not too bothered about the front, as I double tie them, and if they slip down a little they won't be noticed under the water.
Probably not a good idea to wear them for diving off the 10m board, mind.
But yes, I wear them for lap swimming and I did a longer session than normal yesterday as they were so comfortable.
