I think it's just that op hates him passionately and saw a picture of him skiing and so decided to call him a gaper, regardless of anything he actually did or wore to reveal himself as such.
He could be a much, much better skier than op can ever hope to be and she would still, almost undoubtedly, consider him a gaper, such is her level of butthurt towards this celebrity she probably never has, and never will, meet.
