Oakley Proven Snow Dual Lens Goggles

If you're looking to upgrade your ski goggles, check out Oakley's Proven goggles. The angular styling gives them an appealing aggressive look. I also really like the matte color choices (the above pair is in matte black). Overall these goggles look really solid, and at $50 dollars, seem like a great deal too. Check out what Acquire had to say here.

The key feature of the Proven goggles is:

• Dual Lens System: The two lens layers are separated by a thin layer of air, which creates a thermal shield that prevents fog buildup.

Understand other important features (that are pretty common in most quality goggles):

• LEXAN® lens: The LEXAN® lens is made of a highly durable polycarbonate resin thermoplastic that is stronger and more impact resistant than glass and plexiglass. It's the same stuff that the guys on MythBusters use to protect themselves from explosions.
• Anti-Fog Treatment: The anti-fog treatment prevents water from condensing on the lens. Basically the anti-fog treatment works by minimizing the surface tension of the lens, which makes moisture on the lens spread to cover a larger surface area (i.e. a non-scattering film of water) instead of forming compact droplets (i.e. fog). (Read about wetting if you want to know more). Cool fact: anti-fog agents were initially developed by NASA for space helmet visors and aircraft windshields. By the way, avoid touching your lenses or you might wipe the anti-fog treatment off.
  
• Venting: let's heat and vapor out (from between your face and the inside of the goggles). Resulting in more comfort and less fog (and less sweat).
