Actually it was pretty funny watching my boys regularly clearing their goggles in the chopper!
Couple issues that I hope Abom addresses in a second generation. The button to turn on the anti-fog function on the right side of the goggle is a little hard to find with gloves on. Also, the light in the upper right corner is a little hard to see with the goggle on in brighter light so it is sometimes hard to tell if you have turned the anti-fog function on. It would be great to have an audible confirmation but that may not be practicable with available battery life. Don't yet have a feel for extended battery life and how fast the battery life degrades. At first blush, battery life was no issue using the anti-fog technology as I detailed above.
As others have commented here, the goggles are on the large side. This did present a challenge with a Smith helmet. I found the combination pushed the goggle down on my nose and made breathing more difficult out of my nose. I found myself pushing the goggle helmet combination up on a regular basis to clear up breathing through my nose. Not sure why the made the goggle this big and I am encourage by some reports that the will be coming out with smaller models next year.
Given all of the above, good and sort of bad, you should run and buy these goggles immediately if you want to insure fog will never be an issue on your snow adventure. I have tried about every goggle over the years and Abom has finally solved the fog problem. Any other issues are a small price to pay and hopefully even those issues will be in the rear view mirror next season.
