Whether you're getting your reps in at the batting cages or just playing a mellow round of nine, the Oakley Flak Jacket 2.0 XL Sunglasses are game for whatever you are. While maintaining a standard frame size, the "XL" reveals itself in the enhanced coverage of the High Definition Optics lenses that offer a staggering 8.75-curvature to optimize every millimeter of your peripheral vision while protecting you from sun, wind, and impact. The stress-resistant O-Matter frame allows you to slide into second without fear of your glasses being out for the count. The soft, hydrophilic Unobtanium temple detailing increases its grip the more you sweat, so your vision is never compromised no matter how tight the game gets.
