  • Familiarity:I've used it several times
  • Fit:True to size

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. These being XL models provide an even greater field of view, protection from wind and debris, and never "leak" light. The tradeoff is that I feel like a total spaceman wearing them, even more so than the standard Radarlocks.

The straight stem is billed as being more "helmet friendly" than the standard stems, but I have never had a problem with any of my Oakleys fitting with my helmets, and honestly do not notice much of a difference.

I had previous XL Straight Stem experience with my Photochromic models, and love those, so I went for these, mostly for the VR28 lens, which is a great trail lens, second only to the VR28 Black Iridium lens in my opinion. I suspected that the Black Iridium lens would be too dark for my taste; I tend to prefer lenses in the 15-18% range, and they are a 10% lens.

The good: Everything above. The VR28 is a great lens tint and really helps with identifying terrain (I am a mountain biker).

The bad: The Black Iridiums are pretty dark, although I have used them on sunny days and on rides where I knew there would be a considerable stretch on the road.

These did not make my starting rotation, which right now is my Troy Lee Racing Jackets with the VR28 Black Iridium lenses in, my Custom Racing Jackets with my Jade Iridium lenses, and rounding out the starting rotation are my aforementioned photochromic Radarlocks in XL straight stem.

I am still very happy with these, and recommend them highly. I bought in winter; I may be more impressed with the Black Iridiums next summer.

Outstanding visibility.

I'm a road cyclist. I rode a few different pairs of Oaks before I landed on these.

The main point of difference on the XLs is the height of the lens. These are tall enough that when you're in the drops, the top of the frames don't block your field of vision. This was not true of the standard Radarlock lenses.

I also rode a few months with the Radarlock XL photochromic lenses. I found that they didn't get dark enough for my taste in bright sunlight.
