I am highly impressed with these goggles. They are really low-profile and sit really close to your eyes, which is helpful for me because they don't get in the way when I run NVGs. They aren't completely fog-proof (but, then again, no goggles are), and fog up a little bit when you're standing still. It usually clears up once you start moving again. If it doesn't, just give it a quick wipe with an anti-fog cloth and you're good to go.
A lot of people have an issue with this, which I don't entirely understand. In my opinion, if you're involved in a gunfight, you probably won't be standing around that much. Anyways, I highly recommend getting Smith Optics' shock cord kit in conjunction with these goggles, because the included strap will break after a while and the shock cord straps give you better ventilation.
Overall, I couldn't be more happy with these goggles. They're a great product for a great price. I highly recommend them.
- Low-profile, full-seal and lightweight
- Very clear lenses
- Gives a wide field of view
- Sometimes fog when standing still (This isn't really a con to me, but to each his own)
- Original strap should be replaced.
- No interchangeable lens.
