I've been swimming more and more and am getting faster, but I've noticed that I'm the only man in the pool with regular swimming truncks (the baggy kind that people wear at the beach). The other male swimmers either have the speedo brief type suit or the longer tight-fitting jammers.
I have two questions about swimming suits.
1. Will changing from my regular, baggy swimsuit to either the speedo type or a jammer type suit help me swim faster? If so, will it help much?
2. In looking at the jammer type suits, I've noticed that they can be made from nylon/spandex or polyester. Which of these fabrics is best for pool training and maybe use in a triathlon?
Thanks in advance!
