I went for a short hike to a great powder line the other day. Unfortunately I couldn't see much of my hike and had to stop frequently on my ski line because these goggles fogged incessantly. I do not recommend them. I know I'm a sweaty guy and have more problems with goggles fogging up than most people, but this was ridiculous. The wind was blowing hard and it was pretty cold. It should have been sufficient for the ventilation to deal with the moisture.

The silicone strip that Spy puts on goggle straps is a great innovation. It really keeps them in place on your helmet, especially when you put them up. Unfortunately I had to keep them up on my helmet for most of my morning while wearing them. I couldn't remember why I hadn't worn these goggles in a while, but now I do. I will not be wearing these again. They fit OK with a Smith Variant Brim helmet, although the strap could be a bit longer - it was pretty tight.

these goggles look a great online, but their basic and flat lens loses a lot of the integrity of the goggles. I bought them for a deal and with two lenses, after a few days at alta and snowbird, i already had cracks and huge fog issues, it's worth it to take a hit and get a pair of goggles with spherical lenses (oakley, scott, and some of the better spy models) if you want a solid pair of goggles that wont fog up on you when you need them most.

I have last years model i think. I bought them for 20 bucks off of whiskeymilitia. However they do have the gold Mirrored lens. Really happy with them. Mirror only reflects in certain lights, and had some minor fog when i tucked my bandanna into the goggles, but the problem was easily fixed by making sure i had clear opening at the bottom for the air to escape. A good cheap goggle.

These Spy goggles look pretty sick and haven't fogged up on me yet. The silicone on the strap works well too. I wanted to replace my Smith's because the clip on the back would not fit under my helmet clasp, so I had to shift the goggles to the side and always felt one side pulling more than the other. The strap system on these Spy's work perfectly with my lid. Definitely recommend for the price I paid.
