Oakley turned to cutting-edge athletes like ultramarathon runner Dean Karnazes and Mountain Bike World Champion Thomas Frischknecht for feedback on the futuristic Radarlock Path Photochromic Sunglasses, and what they've heard has been really, really good. It's no surprise, especially considering that the Radarlock Path's photochromic lenses automatically darkens and lightens in response to environmental light. We promise that Oakley actually designed these shades, rather than salvaged them from a crashed alien spaceship from the future (though both scenarios are believable).

    Those are by far the best sport sunglasses I have ever had. Leaving vey early (4:30AM) to train evey morning, I always had the dilemma of which lens to use, given at 6 or so sun comes out. The photochromic feature works better than claimed, and is absolutely seamless for who is wearing them. Great shape as well, and the interchangeable lenses make for a nice piece of beach eyewear when you need one, just add the red polarized mirror lenses and there you go. Super comfortable and stay firmly planted even in the worst of the downhills. Buying my second pair as (bummer) I just lost mine during a water stop at Cape Epic last month.

    A better idea of what the shades look like when the lens is activated (darkened). Photo from the Oakley website.

    One ring to rule them all

    I am a self-admitted addict when it comes to cycling glasses. Radarlocks have been my favorite style, for several reasons. The fit is perfect, they are the lightest weight (and most well-balanced), the frameless (mostly) and single-lens design provides the best field of view, and they fog less than other glasses I own.

    I do a lot of early morning rides, and coastal So Cal is typically either foggy, overcast, or you have a bright morning sunrise in your eyes. Or a combination of all of those as the ride progresses. Most of my favorite trails are a combination of shade, canopy, and exposed sunny areas. The soil is light in color and ruts and other hazards can be difficult to identify.

    So I went for a pair these, mostly for the Clear Black Iridium Photochromic lens, and also to try the XL style (not these, I realize), which provided an unmatched field of view when I tried them on.

    I tend to prefer lenses in the 15-18% range, and these are a 10%-66% lens. They never get too dark for me, but always provide enough coverage. The tint itself is pleasing and comfortable. It also really helps with identifying terrain (I am a mountain biker, but I road ride on my MTB to build my base and to avoid muddy trails in winter).

    The bad: I felt like a total spaceman wearing the XLs. Yes, that is a fairly pathetic (and vain) complaint. So I bought these in the standard Radarlock models, and tend to wear them more frequently (again, strictly a vanity issue). The XLs are better glasses, though, just by virtue of the field of view.

    All said, if I could only own one pair of cycling glasses, these or the XLs would be the pair. They do it all, and do it well. I am very happy with these, and recommend them highly.

    These are the stars in my starting rotation, which right now consists of my TdF Radarlocks with the +Red Iridium lenses, my aforementioned Clear Black Iridium Photochromic XL Straight Stem Radarlocks, and these.

    Great review Cam! Thanks for sharing your experience!
