What is the best speedo to wear?
Get the speedo. It says “I’m mature and serious about my sport, so I don’t care what you think.” Jammers are for those guys who aren’t confident enough to wear the right uniform for the job. Less clothing =faster swimming! Unless you think jammers are more comfortable, than it’s okay. I recamend a small. It sounds like your size. But go to the store and try them on. That way you know what you want and can see what looks best on you.
