Excellent service from Zappos as usual. I have a larger face and these glasses fit better and are way more comfortable than the V1 Ti's I had before and sent back. These sunglasses are the Smith Optics: PIVLOCK V90 MAX in brown crystal; they come with 3 sets of the interchangeable lenses—bronze mirror, ignitor and clear mirror (why clear in sunglasses is beyond me--the only drawback) One tip: Get the pair with that comes with the ignitor (reddish lenses) and the bronze mirror set --- I can't explain what it is about the ignitor lenses but that reddish color for me is PURFECT. I live in Florida and the color works great in very bright sunlight and also very little light where you hardly need sunglasses--the bronze mirror that came with them works the same way. When I'm wearing the ignitor I don't get a reddish tint for some strange reason--they are simply great--and the bronze mirror not only looks great with the brown frames but does a fantastic job filtering the light. Read all the links on the SMITH OPTICS site and it really explains a lot about the curvature of the glasses and how the light comes thru without any distortion. I called Smith and talked to their customer service people and they were great----AND THEY REALLY DO STAND BEHIND THEIR WARRANTY. And EVERYBODY knows about ZAPPOS OUTSTANDING CUSTOMER SERVICE--I am a VERY HAPPY CAMPER.

I tried both the V90 and V90 Max. I decided to get V90 Max for both my husband and me. I will use them primarily for cycling. The lens on the V90 Max is bigger so no issue with sunlight/glare around the edges. The yellow mirrors are nice, and dark, while the ignitor lens will be great for grey days. Nice!

I own a pair of these, and the smaller V90. I prefer the coverage of the Max for all activities; the regular V90 let's in a small amount of light and breeze through the lower part of the lens. Add to that the frameless design, and you've got a winner for just about any sport. My favorite sport glass since the Briko Sprinter. The smaller v90 might be preferable to those with smaller faces...? Only one minor issue: the combination of sweat, and wearing these under helmets(full face helmets) has led to the earpiece rubber coming loose on one side. Not a major issue, and could be glued, which I haven't yet done... I just have to be a little careful not to lose it when taking the glasses off from under a helmet.
