For the price, these glasses are excellent. Close fitting comfortable and cheap. In winter they are liable to steam up whilst stationary. Perhaps anti fog coating would help this but I wouldn’t expect it at this price and it’s a minor annoyance.

I got these to protect my eyes from flys. My sunglasses do the same job however when driving through forest the sunglasses make it hard to see tree routes. The yellow glasses actually enhance your vision in shaded light.

Some of the best glasses I have cyclopark with and so considering the price they are a bargain

They do fig up a little but only when stationary. But they are light and clear. If they get damaged at this price I can replace then why time.
