BEST FOR: RUNNING

At 16.4 grams, the Blancas are barely noticeable but won't fall off your face during sweaty sprints, thanks to ample hydrophobic temple padding. The shades are well ventilated, too, and come with two pairs of easy-to-swap, impact-resistant polycarbonate lenses – one for low light and one that reduces irritating infrared radiation. You'd be hard-pressed to find a better combination of price and performance. [Start at $130; nativeyewear.com]
