Just like the classic Shield sunglasses but with a smaller fit. The Shield M are Bomber all-mountain sunnies with ultra high performance lens for the best possible visibility in variable mountain lighting. The removable side shields seal out reflected light from snow or granite, and are plush to the touch for all-day comfort. Soft, grippy coatings at the nose and temples lock these glass in place, to you can focus on sending the route instead of adjusting your eyewear. The earpieces also include attachment points for a keeper cord. If you want glasses that go seamlessly from High Sierra climbs to steep ski descents, these are the pair for you.
