Seeing it's ventilated more than any helmet in Oakley's line-up, it only weighs 295 grams, meaning you'll barely even feel it there on longer rides. Besides being airy-cool and extremely lightweight atop your head, the Aro3 integrates seamlessly with your favorite shades. This is due to Oakley's use of a Boa 360-degree fit system, complete with lie-flat nylon bands that won't snag or catch on sunglasses arms like other fit systems on the market.
