At spring break, I skied without using sunscreen and my face mask was around my chin 90% of the time. I ended up with an insane goggle tan. Fast forward 4 weeks, and its still here. Everyone who doesn't ski just laughs at it and makes cheesy comments like "It looks like you have dirt on your face" or "It looks like you have really bad makeup contouring".
So to summarize it, yes, goggle tans are dope, but at some point they start to attract a ton of attention and it can get annoying. People still come up to me and say "oh your tan line is starting to fade away!"
