Wore my six year old TYR fabric to my ankles body suit at a 3-mile openwater swim today. I've been going in briefs all summer long but wanted to give it try today to see if it made a difference. I Don't believe I received a lot of speed benefit however I did notice I did not get any leg cramping which I had been getting especially in the last mile. I was able to keep a strong kick going which helped me maintain my stoke count. I'm thinking having my legs encased in nylon might have helped. So I hope Masters at the very least votes to keep fabric body suits as there are several benefits, no shaving and possibly less leg cramps.
