It's amazing what a little technology can do.

You're a few minutes into your run, and you've started working up a bit of a sweat. This seems to be the point where your sunglasses start to slip, and you have to throw your flow to keep pushing them back into place. The Spy Alpha Sunglasses employ high-tech materials that help keep your shades in place so you can focus on your pace.

  • Hytrel nose pads increase their grip when your face gets sweaty or wet so your shades are less likely to slip off
  • Interchangeable lenses let you switch things up for optimal vision in all kinds of light
  • Hydrophobic and oleophobic lens coatings keep moisture and oils from building up

Great Glasses

  • Familiarity:I've put it through the wringer

After thoroughly scratching my last set of glasses, I spent a while looking at options and finally settled on these. I only have the one set of lenses so I can't comment on swapping them out, but the blue spectra lenses have a nice tone to them. It would be nice if they were polarized, but they are still great. The nose pieces are soft and tacky but not sticky and help the glasses stay put. They're light and flexible and I forget about them once they are on, just as it should be.

  • Fit:True to size

I've been a Spy fan for a long time, so I'm stoked to see that they're making a couple models of sport shades. They are perfect for cycling, or any time I need a pair of shades that will stay put on my face a little better. The arm and nose pads are incredibly grippy which is definitely necessary if I get the least bit sweaty.
