When I was going to go skiing for the first time, I wasn't sure what I really needed and what was just over the top when it came to equipment. My brother had told me I should really get some goggles. I wasn't looking for anything fancy, but I didn't want them to be huge and ugly.
I found these Scott goggles on sale and decided to try them. They said they had vents on the top and bottom of the goggles to help prevent fog and condensation and circulate fresh air to your face. I found NONE of them to be true!
These goggles did stay fog free for about the first hour of our first day. After that, they would start fogging as soon as I put them over my eyes. I even tried the whole diving mask trick of spitting in them, but that did no good. I ended up wearing them on my hat the whole rest of the time.
I never felt fresh air circulating through the goggles. This was fine with me though because it was cold outside. I would put them over my face every now and then just to keep the wind from burning my eyes. They did a really good job at that at least.
I bought the pair that had a red tint to the lenses because it said it would cut the glare and blinding white of the snow. Well, yes that was true, but it turned everything red! When I ski, I don't want to see everything red, I want to see the beauty of the slopes! I later found out that the lens pops in and out, but if you're not very careful it will snap at on of the attachment points.
I would recommend wearing goggles to ski in, but definitely not these! Stick to the clear lenses too!
