Replying to G suit

alright so let me get this straight right off the bat, i don't want any oppinions on the G suit whether you think its the sickest thing in the world or you can't stand how gay someone looks in it. I was just wondering what is the deal with it? some kids have it but they like stopped selling them and now pros can pop open fresh ones whenever they want? is there some reasom behind the fact that no one can buy them but pros can snag a new one whenever they get a rip in theirs? And if its suppost to be exclusive to pros then why do some random kids have them?
