Technically it's the gap in between the hat/helmet and goggles/glasses. It's used as a term for first timers or those still learning I don't think I've ever heard anyone refer to little kids as gapers.
i saw the epitome of a gaper once. he had 05-06 foils but he was wearing jeans, a tight addidas windbreaker, and had a huge gap between the helmet and gogs
yep. u dont even need to know the word "gaper"... when ur up skiing and u see a gaper, even if uve never heard the word before in your life, you will say "fuckin gaper"...
