Pretty good

Who buys super expensive lenses for the possibility of them getting totally wrecked if you bail. These glasses are inexpensive, feel durable and fit comfortably. I have bad vision and only wear clear glasses or goggles when mountain biking. i tried several brands and pairs of glasses and these were my final choice. i didnt want to spend a ton of money and wanted them to be clear and not fog. these fit the bill. i dont wear these on the climb up, so not sure about heavy sweating and fog. but on the long decent they proved most valuable. stopping dirt and freaking flies but hitting my eyes. they were super comfortable. i dont really like the black nose guard, its a little distracting which eventually i dont notice it. but its sort of annoying for the first mile or so of decent.... i wore mine in a misty rain the other weekend and i found myself having to stop rather frequently to stop fogging and rain drop build up...they didnt streak off very well and i ended up taking them off which then got dirt splashed in my eyes....but all in all, for the price they are great!!

Outstanding quality and value.

I've put it through the wringer

The glasses are light yet sturdy and for half the price rival Oakley's easily. They offer the multiple lenses as part of the base price which Oakley's cost extra. I think overall they are a better product. The fit around the temples do not cause headaches. I will by products till I get the one that best perform.
