Oakley Flak 2.0 Prizm sunglasses review

Oakley says that the Flak 2.0 Prizm sunglasses are not only suitable for cycling but also a variety of other sports including trail running, rock climbing and golf.

They come with two separate lenses, rather than the wide one-piece lens found on many cycling specific sunnies - like the Oakley JawBreaker and the BBB Select sunglasses.

The lenses use Oakley’s Prizm technology to maximise contrasts and its patented High Definition Optics to enhance visual clarity.

The result is great visibility, particularly in changing light conditions.

The Oakley Flak 2.0 come in a standard size and on the Cycling Weekly scales came in at a sprightly 24g - 10g lighter than the JawBreakers.

>>> The sunglasses saving device you never knew you needed

The rubber-like Unobtanium nosepiece and arms keep the glasses in place - I didn't experience any real slippage or movement - and along with the very low weight give a comfortable fit. I was almost unaware I was wearing them.

Some may not be a fan of the relatively small lenses, but they provide sufficient coverage and it is only when riding in the most extreme and aggressive positions that you notice the frame in your peripheral vision.
