Love these. I have the Zebra lens, which is a transition lens suitable for very low-light conditions right up to midday summer Utah sun. The lenses have excellent visibility and they do not fog up. I put them on in the car before a trip to go tour and don't take them off until I've parked in the garage back at home, simple and one less thing to fiddle with at transition time. I wear them all year round - I bought them for ski touring but I now also use them for running, hiking, biking, climbing, any other outdoor activity. They protect my eyes well enough unless it's snowing somewhat heavily, in which case I have some Julbo goggles with the same lens. Out of vanity I ordered black sideguards from Julbo's site for something like $6, which reduces somewhat the rather garish appearance... and I don't find myself ever using the removable sweat-guard. The green backs of the ear rests are malleable and can be bent to fit your face, which is very nice as you can "fit" them around a winter hat for touring and easily back to a summer running fit with no difficulty.
I've thought about buying the Camel lens just because I like them so much. Spendy, but absolutely worth it for these glasses, in my opinion.
