I started skiing again two seasons ago after 14 years off from skiing as a kid. I initially purchased a pair of Scott goggles from the local ski shop for around 75. They've become consistently more scratched, tend to fog and at times even have had water condensing in them. Finally I bit the bullet and purchased some A frames.
The downside (let's get it out of the way):
* The particular pair I got seemed to have excess glue keeping the foam attached to the main body, keeping it in a constant state of sticky. I returned these and the new pairs seems fine.
* These aren't indestructible, they will scratch if you aren't careful and you won't get the scratch out, especially on the inside lens.
* The fit is pretty good, super adjustable, and the strap stays in place on a helmet.
* They're comfortable to wear and don't limit vision very much due to the very large lens.
* Although I only got about 4 days of ski time to test them, I was in some of the warmest and most humid weather of the year. Almost no fogging occurred no matter how much heat and sweat I put out, and as soon as you started down the trail the fog dissipated instantly.
* Interchangeable lenses mean you can have one set of goggles to go from night skiing all the way through bluebird skies. It's a little difficult to change the lenses at first, and I did decide to pick up a separate pair for night skiing, but I have two shades of lenses for day skiing to handle both direct sun and overcast days.
* You can't beat Backcountry's return policy.
* Keep the cleaning bag with you, if you're taking your helmet off you head, take your glasses off your helmet and store them so they don't get scratched.
* DO NOT touch the inside lens while wet. Read the attached info on how to deal with water/snow on the inside lens (and on how to do lens changes, also see youtube).
* To remove the lens, don't focus so much on pushing the lens outward (away from the eyes). Just grab the top of the frame in your right hand, the nose bridge in the other, and pull apart from each other and away from the lens. The lens should start to come right out. You can be pretty rough with the frame and lens without worry, but try to use the cleaning bag or something similar to prevent directly touching the lens.
