When our contact from Verde PR asked if we would like to try these new shades out, she included a link to the product in the message. Since I was in such a rush to respond in effort to beat CG and the rest of the MBT crew out of a test, I didn't take the time to fully read and research the product... on my phone... in the middle of the night.

Anyway, since I didn't specify which color I'd like to rock out, I had no complaints when the white and yellow ones showed up. This is a great color combination if you are a cool hipster teenager wearing a trucker hat with your shag hairdo, but I'm kinda old and this look wasn't really for me. This of course is a personal preference, which could be easily remedied by something as simple as say, grabbing some black ones next time.

Before I get started with the Julbo's let me state for the record that I am a bit of a sunglass snob. The products of Oakley, Rayban and the like have been gracing my peepers for years and I have currently been rocking a pair of Tifosi's for the last few months so I think I can comfortably call myself an aware consumer in the $80 - $120 eyewear market.

Starting off, the Julbo's show up in this nifty little carrying case, which you will probably never use because you won't want to take these glasses off. As I said before, what disappointment I found in the color combination was offset by the experience of putting these shades on my face. The lenses are Julbo's own yellow tint Zebra, which are light sensitive and adjust to your current lighting conditions. The yellow base color excels in low light conditions such as trail riding in the woods and brings everything in range into sharp, clear focus; eliminating the ageless excuse, "I didn't see that coming".

When you jump out of the woods and into direct sunlight, the lenses automatically darken in about 20 seconds to block out unwanted direct light. While this darkening is perfectly capable of making the bright sun behave, it is retains a yellow tint, which is perfect for riding applications.

The Zebra lens is also treated with some kind of wild space age anti-fog coating that actually works so well that even riding in Florida's 100+ degree weather, I couldn't get these lenses to fog up. The Dirt frames are made out of lightweight plastic with rubber overmolding at the ear stems and were specifically designed to be worn with helmets. I know, I know, we've heard all this before, but like all things Julbo they actually do what they say. In fact my testing period involved under-helmet use so I can report that the engineers did their homework here.

For daily wear I think the fit is a bit snug but this translates to a perfect grip to you head when you're on the trail. After a few days I didn't even notice the extra pressure anymore. What I did notice was that when I was ripping my local trails with these shades on, they tended to stayed put, under my helmet (skate style and vented bike style) all day long with no fogging, no slipping and no discomfort. Another point worthy of mention is that whether by intentional design, or by accident the way the frame contacts your face actually channels the sweat down and around your face keeping it out of your eyes and off the lens.

Bottom line, in an activity where I had previously given up wearing protective eyewear because of the poor fit, fogging lenses and hassle I have found a new friend in these glasses.
