A high quality pair of photochromic sunglasses for a reasonable price. The build quality is excellent, they feel premium, they are lightweight, and they fit great on my relatively large head. The mono shield does a great job at blocking wind, and it's basically impossible to get these to fog up even in winter wearing a face cover. The photochromic lens works as expected, as they darken and lighten within a minute or so. With CAT2 at their darkest, they're not the best fit for very sunny days, although you can make it work. The CAT0 rating is nice for overcast weather or when the sun starts to set, but I wouldn't recommend them strictly for evening/nighttime, as they are amber tinted and they do make visibility a bit worse than fully transparent sunglasses (and yea they are transparent orange, with a blue mirror, so the photos on this site are a little misleading in that aspect). Personally I really like these for cross-country skiing, as the tint creates a nice warm tone and a bit of contrast, and they are usable in nearly all weather conditions.
One last thing, I bought mine from a 3rd party retailer and sadly mine came with slight micro scratches on one of the sides, and I'm not sure yet if these are just a bit prone to scratching or if it's a mishandling on the part of the seller. Since the product description doesn't mention anti-scratch properties, this might be an issue for some people.
