yeah- I hate judging videos- but I would say they wouldn't pass IPF, they look a few inches high.
Is this dude USPF? Just asking because some of the US guys who say they hit numbers in single ply but in USPF single ply means single ply plus briefs. In my book thats no where near the same as single ply by IPF definitions. A tight pair of briefs is almost as good as a squat suit. So, call me a purist, but briefs plus single ply is actually double ply. Strong dude for sure.
