I am a returnee to skiing after a couple decades' layoff. I needed goggles. These looked reputable and were discounted. I went skiing for half a day in classic New England conditions--howling winds and blowing snow; bright sunshine and then overcast. I put the goggles on when I stepped out on the slope and never really thought about them for the rest of the day. Which is what was so amazing. They were remarkably solid, superbly comfortable, never even slightly hinted that they were fogging up, and allowed me to completely forget that I had them on--except that I could see perfectly clearly the entire time. They performed equally well in bright as well as grey conditions. When it really started to darken, yellow lenses might have helped more--but these were remarkably adequate considering I don't think they are low-light specific. Having grown up with goggles that were a constant problem, these were a godsend. Especially the comfort part--rock solid in place, secure but gentle. Amazing. I am very glad to have come across them.
