I am new at triathlons because I just learned to swim last year. I wear these shorts for my swim training and they are helping me a lot as I’ve cut a few seconds off of each 100 meters. Further, as I’m practicing my transitions, these shorts have been really nice to wear over my tri shorts and I just keep them on for the bike ride as they are not getting too hot (although now that it’s getting over 85 degrees, I may strip them off before I jump on the bike). Further, when I do take them off, rather it be before or after the bike ride, they come off fast. I really like these and recommend them for newer swimmers to get their body buoyancy better in the pool and I’d recommend them for triathletes at all levels. Lastly, everyone says these are for open water but since they do not get too hot, I use them in my lap swimming all the time.
