Oakley. Oakley. Oakley.

I am a HUGE fan of the brand, and have been a happy customer for over a decade. I've been through many pairs, and loved them all. For athletics, my current favorite are the Half Jackets. For cycling, I really like to have a pair with no bottom rim, because it clears your field of vision when looking backwards (to check to see if there are cars coming, for example). But the Half Jackets are nice because they're not as wild as the other cycling-specific frames (like M-Frame and Radar), so they can be worn in casual situations without looking too zany.

They're so good that I currently have three pairs, for various lighting conditions. However, if you only want to get one pair, you can still get extra lenses and swap them out whenever. Here are my sets in all their glory (I'm also a semi-pro photographer):

No, I don't work for Oakley. I just like their stuff. A lot. One pair you didn't mention yet is the Radar, which is supposed to replace the M-Frame. Also very customizable, comfortable, and slick. I simply prefer the look of my Half Jackets. You can get Oakleys in custom color combinations at http://www.oakley.com/custom

I am loving the pair of Nike Odeon sunglass I just got.

yeah i should've said that at the beginning, i just figured most ppl here are triathletes.

i do ride a tri bike and i too have the problem of the top rim being in my field of vision, and its annoying to say the least.

i've been trying to find a decent pair of no rim glasses but the downfall of those is that you cant change lenses easily like it seems you can with the Oakley's and others.

Oakley is great... I wear some Oakley "Fives" for everyday use.

However, I didn't have much of a budget for sport glasses, so I picked up a pair of Tifosi glasses at my LBS. They are pretty inexpensive, and come with 4 interchangeable lenses.

I was a fan of Oakleys for a long time. And you can't go too far wrong with M-frames or their other models.

But you may want to check out Rudy Project as well. I've been wearing Rydons for a year now, and I won;t go back. Good clarity, very adjustable fit, lighweight and scratched lenses replaced for the cost of shipping.

One thing I should add as well, is that Oakley lenses are all OSHA rated for impact resistance.

I'd like to throw the specialzed San Remo's. they have a larger frame that sits farther up on your face to remedy the top bar problem.

I just got a pair of Oakley Flak Jackets like the ones mentioned by CGroth and I love them. I have been wearing Oakleys for more then 10 years and I am truly addicted to their sunglasses. I once tried a pair of their sandals and was disappointed but that is another topic.

A few notes on the Flak Jacket. I love the replaceable lenses so that when I go out for a ride before sunrise I put in a pair of clear lenses to keep the bugs out of my eyes. Also if you scratch a lens you don't need to send the glasses in for repair just order a new lens and change it yourself. The coating that is supposed to keep dust, dirt, water and sunscreen off works well but sometimes leaves a little smudge; it is still way better than before. I am not sure if they have polarized lenses or not because that is not important to me. The Oakley store near me did mention that they are developing a set of transition lenses (very cool).

I also think that they look pretty cool.

I'm a big fan of oakley as well I have a lot of pairs of designer sunglasses the only ones i don't like from oakley are their mp3 player ones i mean I have an ipod when im out riding and having something that big and bulky on my face i really dont care for. They are light but still awkward to wear i think.

I won a pair of Oakleys and chose the flak jackets with polarized lenses. I have been wearing this pair constantly for about a year and have really liked them. (I have to wear sun glasses at all times outside because an injury makes one eye extremely sensitivity to light.)

While honestly I am dedicated to Rudy Projects glasses for sports/being active, you really just need to go and try a bunch of different frames on. You will find that one frame that matches your face/head perfectly and a bunch that just do an ok job at it. Oakly, Rudy, Natives,Tifosis, Ray Ban, any of them all make good products and its really just up to you. Dont settle for a frame that causes any discomfort or irritate you at all just keep trying new ones tell you find the one that fits you perfectly.
