These are a great pair of glasses for the trail. After my last glasses pinched my eyebrow against my helmet in a crash, splitting it open, I decided it might be time to get some dedicated riding glasses. I wanted something that was plastic framed, had interchangeable lenses, a firm grip, and larger lenses that would not trap my eyebrow as before. These are perfect, the rose lenses are great for the shady trails in my area, firm yet comfortable grip on the head without interfering w/ my Fox Flux helmet, and lenses/frames that are large enough to give me a completely shaded view (I cant see any of the frame when they're on)All this, and they're less expensive than their Smith counterparts...easy win.
