First ride in the Jawbreaker, 40mi... (CVNDSH Polished Black/Prizm Road) here's my Review (as a Cyclist/Rider)
Field of Vision: Exceptional, unobstructed views; everywhere I looked was PRIZM Road. The view normally obstructed by the Radarlock frame is nearly nonexistent; a huge improvement over the Radarlock. I could see the edge of my helmet and it felt as if I was in my own cockpit behind this lens.
Lens: PRIZM Road is amazing; venting on this lens far exceeded what I was expecting; had very minimal sweat on the back of the lens after the ride. The sweat that was there was only at the bottom left & unnoticeable; bottom left & right of the lens also provide unobstructed view when looking back over your shoulder for traffic. No sweat landed on the back of the lens in my field of vision the entire ride. That is AMAZING! Last thing a cyclist wants is a dried sweat drop on the inside of a lens while riding. There is also a cutout in the lens channel to prevent sweat pooling; common with the Racing Jacket. I had no issues with my contacts drying out... which I never do with my Oakley Sport Frames.
Frame: Almost weightless; at times I forgot it was there; I am still getting used to the different fit coming from the Radarlock & Racing Jacket. The adjustable stems are nice, had mine in all the way and they just cleared my helmet strap; and they're much thinner and can comfortably slide under the helmet strap if needed. At times I felt that if I looked down, they would fall off, but they didn't. They sat securely on my face... have a feeling it's because of they're reduced weight.
Fit: I used them tonight with the installed nose-pads; I felt as if I needed more during the ride as I wanted the frame even closer, more snug, to my face. But doing so pushed the frame into my nose bridge. Sure enough, when I opened up the box, the spare nose-pad was thicker... so I'll be using that one on my next ride. Even though I have a large nose, my nose bride is thin.
Final Thought: These are a must have for a cyclist, the R&D that went into them is amazingly evident.
