Julbo Trek Sunglasses

Transition lenses work perfectly. They are very comfortable on face. Also, with the back strap they stay on your face snuggly with heavy excercise/ movt. Lastly, sweat guard over brim prevents sweat from drainin onto lenses and obscuring view. Great pair of glasses.

So far I'm very pleased with this purchase. The product is pricey, but it's clearly of high quality and the photochromic lenses function well. I still need to test in snow conditions, but am more than happy with its performance for general mountaineering purposes.

I gave the glasses to my brother who practices athletics. he has used them in several urban and rural races. according to it they are very good and in their last competition they were vital since the sun was in front in the ascent so the glasses allowed him to run without affecting the sight by the luminosity

These are my favorite shades. They have adjustable fit and thus they are very snug. The lenses are incredible and the colors are great. Highly recommended!

Great Glasses! The Camel lenses are great for snow and driving while the Zebra lenses are better for trail running and hiking in mixed shadows and sun. With both sets of lenses, I have a full quiver for all conditions I need glasses for. They are well ventilated and only fog slightly running uphill in high humidity. A great set of glasses for anyone spending time in the mountains.

Great sunglasses just wish they had them in "reader" style too.

Transition from light to dark is fast, and not noticeable (which is good because it means the glasses are regulating light in dark to bright conditions so well that you don't notice the changes!) From cycling in Houston, to skiing in Colorado's mountain, I have been happy with they performance. The lenses tend to attract dirt on the inside facing side.

Very good glasses for the outdoors especially where you are active (running, climbing, biking) and stability are important. I have the Camel lens which offers the most (I believe) UV and light reduction and I love them. If you sweat a lot the included foam band is very helpful.

die Belüftung ist super...sie läuft nicht an auch an wenn man viel schwitzt... dieses Problem ist mit vielen anderen Sportbrillen nicht gelöst...und Funktion kommt vor Aussehen!
