I'm totally old school and still consider Pluto a planet #NeverForget So, I was excited to come across this right before our vacay to NASA for spring break! While not too many people noticed (and I'm guessing nobody under 30 had a clue what it meant) I did get a huge chuckle from Astronaut Brian Duffy whom we were lucky enough to meet and chat with! Quality seems good although I found it slightly smaller than other men's mediums but not drastic. If you're right on the edge of sizes I would go up. I'm sure I'll be wearing it alot!
