It's not a squat suit, it's a singlet like they wear in wrestling. He wasn't getting anything out of it, he has to wear it because it's in the rules, they want a clear look at the hip and butt to make sure there isn't butt lift that will help with the lift. The wrist wraps aren't adding much.
He didn't make it for a few of reasons -
1) He opened too high.
2) The attempts had too much time between them. This meet was long, 20 - 30 minutes between attempts, that saps your strength.
3) Third attempt, he just got caught in a bad bench groove. It got too out in front of him, and started to drift toward his feet, with 700 plus pounds, you can't correct that too much when it happens.
I appreciate the well reasoned reply. I actually did learn something. However I still think that they should not be wearing the belt, wrist wraps, or the singlet if it is thick compressive material. If the singlet is not, strike that third point.
