Just what I was looking for


Reviewed By: Lu on 5/31/18

These glasses are super. I knew I needed a new pair, as my old (free) pair were scratched up and didn’t really provide all the protection I needed. I decided to give these a try, since for the price, they offered a lot. I have been very happy with my purchase. They darken quickly when you need them to and stay clear when it’s not bright out. The directions say not to wear these during low light conditions and I have to agree. I did not feel safe with them on in the evening. I like to have glasses on all the time, so that is a drawback, but the only drawback.

best for mountain biking in forest


Reviewed By: Bonnie on 7/18/17

I really enjoy these glasses in while mountain biking in the forest. I can clearly see into the shadows and that is truly a wonderful thing. But otherwise--not so much. I have 2 concerns. 1. The tinting does not get dark enough for my 55-year old eyes. I live in the Sierra, a place with intense sunshine, so I get a head ache from wearing them on a road ride during the middle of the day. 2. The venting means air flow past my eyeballs, so at higher speeds, I get irritated eyes.

Sunglasses - Slip Fototec


Reviewed By: Janet B on 8/19/14

Just spent 4 days in full range of weather wearing my new shades and must say they are worth it. Cyclosource catalog could add that these are UVA/UVB protected - that keeps me from getting eye strain/headaches while wearing them. Lenses change color quickly and when at their darkest they still appear almost clear to me. This is great when pedaling in and out of bright light and deep, dark shade. Air vent feature was wonderful for minimizing fogging up, even in wicked heat and humidity. One pair does it all. I'm happy.
