When you prestige you get a permanent unlock. If you do it again, without using that first one, will you then have two? With this thread of logic, can you essentially save them up?
It would be pretty useless to save them, except I play on an account with my brother and I let him choose what to unlock since he plays more, so I don't want to waste one if you don't get to keep it.

I'll assume you are referring to Prestige Unlock tokens since you are talking about gear.
I haven't personally made it to 2nd prestige, but I'd be confident that you can bank these if you want, since they are token format and in the previous game you could bank the tokens for later use (and I did so personally).
