Dear Cycling Impressionists, I just tried POC DO Blade sunglasses.
I found them extremely comfortable.
The grilamid frame makes the glasses incredibly light and the hydrophilic rubber nosepieces help the glasses stay steady even in sweaty conditions.
Talking about the lens, anti-fog and ripel treatments keep it always pristine.
The different lens tints increase contrast so that you can always react in time, not stressing too much your bike handling skills.
The lenses are interchangable.
In conclusion, I would definitely suggest POC DO Blade for road and off road cycling.
