I Googled what the best goggles on Amazon were and found a nice article that also mentioned these as the best budget goggles and they definitely are amazing for the price. They look great and stylish like a $200 pair and they never fogged up at all. I saw a fee other people on the mountain with this brand too. MBought the blue ones. They're awesome and I'll probably buy the red ones soon for sunnier days.

Works pretty well. Didn't fit over my glasses however. Other than that no complaints

I bought these on a whim to prevent having to buy an overpriced "Brand Name" version for a ski trip that was a few weeks away. I bought the "Lagopus X Black Frame Polarized Blue Lens VLT 16%" version (so the "S3" darkness). I was pleasantly surprised, goggles came packed in a nice box and in a very nice non-scratch reusable bag/cleaning cloth. The blue is attractive from the outside, and the mirror/polarizing does obscure your face/eyes if it matters. Comfortable and JUST small enough to fit inside a big rental helmet. The strap adjusted from pretty small to gigantic with ease and the grippers on the strap are great! The view through them is exactly what I wanted: Polarized, cheap, clear, ventilated (they don't fog in any way I tried to get them to) and they seem to be VERY wide angle (so no "Goggle/tunnel vision"). When you put them on on a really bright day they seem to be more than adequately dark (polarizing helps with this), i'd imagine the S4 tint is probably too dark for all but the most sunny of days. The S3/Blue VLT 16% seems like a good "all around" lens for everything from whiteout afternoon skiing (did that several days) to windy and cloudless winter mornings (did that too).

The only drawback (if it is one at all) is that the view through the lens I chose makes everything yellow tinted. I don't mind this, helps make out lines and edges quite well, but it does blur the color spectrum between blue and black (if you're a skier/boarder that cares about this, make sure you know what shapes the runs are too!).

All around recommendation: buy them!

Picked these up 4 years ago when they were only $21!
I needed a set of clear goggles since I ski uphill early morning or after the lifts are closed. So I'm skinning in the dark with a head lamp.
Since they're smaller, they're also a bit lighter. They do their job of keeping my face warm on fast descents and not fogging.

I dry them out after each session and the foam is still in great shape. During long stretches on not using them, I stick them in a ziplock back to help preserve the life of the foam.

They are fairly comfortable and stylish. No major issues with function.

The silver finish is the right level of VLT for sunny days in Vail. I will probably buy the polarized lens for reduced glare.

Changing out the lens is not as easy as it could be. The switches on the side must first be turned outward. Then the holes in the lens under these switches must be pulled out, and the 6-8 plastic snaps within the goggle frame have to be pulled out of the lens. All of these steps have significant resistance, all while trying not to break or scratch the lens. I probably won't be changing lenses much.

It was after 2+ hours of skiing and intense sweating that I noticed them fogging. I had a neck gaiter tucked under them the whole time, which probably contributed to the fogging. They didn't fog on a follow-up ski day where I didn't sweat nearly as much.
