YMMV Review

Julbo gave me the opportunity to test the Trail Sunglasses and I have taken them out hiking, running, and cycling. While they are made for trail running, they are equally adept for other activities as well.

Nose Area

Design ★★★★☆

The Julbo Trail Sunglasses are Julbo’s first sunglasses made for trail running. They have a wrapped shape to them to stay in place. The frame is made out of a flexible plastic. There are Elastomer shock absorbers in the nose, temples and sides for comfort and hold. The frames only connect to the lens near the nose creating sunglasses with extraordinary flex. This structure also allows full venting to diminish the accumulation of condensation and fog. The nose bridge uses a 3D Flex Nose which is an ergonomic nose piece adjustable to the nose shape. There is also an Optical Clip; ideal for those who require optical correction and do not wish to wear contact lenses, can be removed if necessary. The curved and wrapped temples are shaped and cut for better hold for sharp and repeated movements. The temple ends have Sipe Grip Tech which is supple, sculpted inserts at the stem ends for excellent hold without sticking to hair.

The Trail Sunglasses use Julbo’s Zebra Soft Lens. This lens is a light-sensitive (photochromatic) lens that the turns darker or lighter depending on the intensity of the light. This process is said to take about 22 – 28 seconds. It takes the visual light transmission from 40.7% to 6.6% or Category 2 – 4 in Julbo’s scale. The lenses provide optical category 1, guaranteeing a 100% protection against UVA, B, and C radiation.  The lens has an anti-fog coating to further suppress condensation and fogging. Julbo’s regular NXT lenses in standard thickness meet the impact requirement defined by the ANSI Z87.1 standard for industrial application. Essentially they are shatterproof. Julbo recommends these lenses for mountain biking, cross-country walking, skiing and riding, running, and climbing.

Fit ★★★½☆

It is difficult to talk about the “fit” of sunglasses. The nose piece on these is fully adjustable but the temples are not. I did not feel like the temples needed any adjusting, they were snug but not too tight. The sunglasses stayed in place well even on a bumpy descent on my mountain bike. The flexible frame allows them to flex when needed which helps comfort.

Performance ★★★★☆

I have liked these sunglasses a lot so far. The optical quality with them is great, I did not notice any loss when putting them on. They are very lightweight and since the lens coverage is large you can barely tell you have sunglasses on. I have not tested the optical clip but I imagine it works well for those who need it. The elastomer material grips well in all conditions and since I do not have much hair to worry about I could not tell if it grips it or not. I really liked the photochromatic lens. They do in fact adjust to the light intensity rather quickly and provided the right amount of visual light for the situation. I did notice that when worn with a hat they would not darken as much due to the bill of the cap shadowing the lens.

Temple Tips

I was not a particular fan of wearing these with a hat so once I realized that this was happening I stopped wearing a hat with these sunglasses. I have worn these on some high intensity climbs and trail runs and the glasses have not fogged at all. I did have some sweat dripping down the lens but that was not the glasses fault. I have not had the opportunity to wear these in the rain yet but I will try to check back in here once I do. Finally I have not tested the shatterproofness of these lenses. Just like with helmets, I do not plan on taking a fall just for this review, I am sure they were tested properly. =)

Overall ★★★★☆

If you are looking for a pair of sunglasses with an extra-wide field of view and medium size, these Julbo Trail Sunglasses are a great option. The Zebra photochromatic lens really works and due to the air flow and treatment they do not fog up. Pair that with the adjustable nose and flexible frame and you have a comfortable pair of sunglasses for a variety of activities. I say a variety even though Julbo aims them more at trail running, I figure at $160 most people will not be able to justify having a different pair of sunglasses for each activity. With sunglasses like these you can be confident your eyes are protected while you tackle a wide range of optical conditions. As always, your mileage may vary.
