Master slacker
Something awesome.
Can't say I've been looking at his suit, but yes, there are reasons for wearing suits that are tight. Most of the reasons, or science, behind the suits are beyond me. I will say, though, that competing in a tight suit is more comfortable than a loose one. That's my personal opinion, which I'm sure is shared by others. I don't want any part of my body jiggling any more than it should. Jiggle is drag. And the last thing you want is there to be enough "looseness" to allow a body part to become the mast of a crotch sail boat on a start or turn.
