The wraparound geometry along with non-slip ear and nose pieces of the Spinshield Air deliver a natural compression fit without undue pressure for excellent comfort and stability. Additionally, Spinshield Air is offered in both standard and Asian fit frames.
For those who normally wear corrective lenses, Spinshield Air is prescription ready via a proprietary Rx optical insert that can easily be clipped to the nosebridge behind the sun lens.
Spinshield Air always delivers a comfortable fit. The ergo-grip integrated rubber tips and nose pads, ensure a snug stable fit while the Pro-Fit geometry of the temples is designed to provide natural comfortable ergonomic fit without annoying pressures on the ear area.
I love my Boost 01 helmet, and these pads keep it going! Great quality too, just as I'd expect of Rudy Project.
These frames do exactly what I need them to do. They carry my Rx lenses so that I can see, adjust filtering / clarity in changing conditions (I have the ImpactX Photochromic 2 Laser Red Lenses) and all without me constantly adjusting them. Often I don't even think about them during a long run until I take them off and realize it is really bright outside! It was an excellent purchase and one that I would make again.
About a year ago I got a Rydon frame and put Rx lenses into the frame. I use these for skiing, hiking, running, walking, ... The frames work great, are very comfortable over the long run and have easily handled the abuse I try not to give them. I am very happy with these glasses!
