Michael W.wrote a review of Roka GP-1X Sunglasses on November 1, 2019
Familiarity: I've put it through the wringer
I bought these because my other sunglasses would slip on my nose (Oakley's). The slipping would really bother me on mountain descents. These Roka's do not slip and there is no frame material at the top. So they are perfect for riding in the drops or going down a mountain - nothing obstructing your view.
