Oakley's got a new sport frame that should be atop your list if you're looking for versatility in changing light conditions. Their new Flak Draft has a single release trigger that instantly pops out the lens for quick and easy lens swaps. They've also stealthily added venting to reduce any potential lens fogging to keep your vision nice and clear all day long. You can also spec it with a variety of Prizm lens options for the trail, golf, and fishing. Prizm takes advantage of their years of color science research to give you enhanced contrast and improved visibility.
