Good fit because of the adjustability but missing the rubber on temple tip and it causes to slip from time to time when I'm running and cycling.

These are very comfortable, lightweight and the vents keep the lenses from fogging up. I use the RX insert and it fits snug and secure. The temples can't be adjusted easily like on the Rydon frames, but that's a minor issue for me as they fit my head perfectly. This pair of glasses came with the photosensitive lenses which are great for variable lighting overall. For mountain biking they don't adjust as quickly as I'd like for going in and out of the tree cover.

Excellent tint and views from these glasses. I have using Rudy Project gear for over 20 years and these are my favorite for MTB racing and training. The bumpers keep the edges from getting nicked up before and after use. Vents work well in early morning mist and fog.
