Outdoor sunglasses usually come in two categories: Way too cheap or way too expensive.
Colorado-based Optic Nerve offers top-quality glasses at reasonable prices. The Autovaughn has the cool styling, quality optics and interchangeable lenses of Smith glasses at half the price.
Where to get them: Ascent Cycling or www.nerveusa.com
Bonus: Vents in the lens keep glasses from fogging
Bummer: Smaller folks may find the Autovaughn too big.
