BEST FOR: Hiking and scrambling way up in the alpine. THE TEST: This big-lens wrap melds sports function with form in the shape of the ventilating metal grillwork at the temples. The Diablo’s rose-tint photochromic poly lenses, with mirrorlike coating to mitigate glare, make depth and detail jump out and holler, and they do it all day as the tint adjusts to brightness. The springy frames and rubber at the ears and nose keep things secure, and we appreciated the extra rubber at the brows to defend against light leaks and sweat. Also good for trail sports, especially tough hiking and mountain biking, as well as mountain-town streets. THE VERDICT: Nice, though maybe not quite nice enough for the full sticker price.
