The dust may be swirling on the trail ahead of you, choking the competitors behind you, or merely riding on you face in the form of the Julbo Dust Zebra Photochromic Sunglasses. Sleek and streamlined, these shades adjust according to the conditions so you can see all and stay one step ahead.
Weaknesses: Temples are not as comfortable as Maui Jims
The photochromatic lens Julbos are great sunglasses and change from light to dark very fast. They are a bit slower changing from dark to light, but still faster than others I have tried. If you ride in the mornings other other times with changing light, the photochromic lenses are by far superior than lenses that are too light or too dark.
