Great vision, lightweight, reliable
I have had little trouble with these goggles. Perfect vision, comfortable on the head (with or without the use of a helmet - I'm using http://www.dogfunk.com/smith-holt-skullcandy-single-shot-audio-helmet?cmp_id=EM_TRN3003&mv_pc=r200&rmid=DF_HYG&rrid=394023448), and you hardly notice you're wearing them. Had no issue with them being 'foggy' as others might suggest - and this includes falling constantly in a LOT of powder runs. Would recommend to anyone!
