It's how you wear a mask that makes a different. N95s won't do anything for you if your mask isn't tight enough and you have leakage.

I traveled to the UK, the land of new variants, a couple of months ago and zero people wearing masks around me and I was fine. I feel pretty safe as long as I have my mask on. That said, I wonder if I should consider double masking just to create a tighter fit when I'm in big crowds at the con.
