Nolan Arenado caught on to these thanks to former teammate and swagger monster Troy Tulowitzki. He’s got his own Mimsbandz now, with his face and the quote “Lets ggoo!!” I think he could have done better with the quote, but they’re still fresh.
Arenado also wore a special version with his mother’s face on it for Mother’s Day 2015.
Unfortunately it doesn’t look like these are available.
