These are the best I have ever owned. They fit like a glove without being uncomfortable at all, offer a nice wide field of view, and the photochromic lens works like a champ from blue bird skies to full-on storm conditions
I've had an UVEX (lower price) and an Oakley (polarized, same price class) and this google of JULBO beats both. The photocromatic and polarized glass of JULBO has a very good contrast even with cloudy sky. Quality of the frame an strap is comparable to Oakley. I don't understand my friends who buy googles with changable glasses when you can buy one glass that shifts between category 2 to 4 automatically.
