Paintball. Ick. Airsoft, ftw! :P
On a few warmer days I've worn (some of) my airsoft loadout on the mountain for something different (see pic below). That said, I think the paitball goggles/mask could be a cool idea. However, I'd have to see a pic of more than just
the mask to be certain (post a pic if you have one).
