As always, AMO products never fail to disappoint. The AMO shield sunglasses weighs in at a feathery 32g which is one of the lightest in the market. The latest release does away with the frame completely and is designed for totally unobstructed vision – a winning feature for any ironman athlete when you have to spend hours in an aero position in my opinion! By eliminating the frame, AMO has created their widest unobstructed range of view yet. With distortion-free, crisp vision across the entire lens, and plenty of coverage to boot, the lightweight glasses literally disappear on your face, leaving you completely immersed in your environment.
Even though the lens forms the main structure of the glasses, they feel surprisingly robust, not flexy or cheap like some frameless sunglasses do. I didn’t experience any fogging even in major humidity, which left a few riding buddies flying blind as they took off from a stop light. The large lens didn’t tap the brow of any of the helmets I tried them with, like some big sports glasses do.
One of the major complaints I’ve had with other brands sunglasses in the past is that the long earsocks tend to overlap with some helmets' retention systems. It's not a major annoyance, but if your helmet moves so will the glasses. Shield and all other AMO models in general has a fully adjustable nosepiece and temple arms designed to be bent to shape and moulded to fit your head which significantly improving comfort and prevent rubbing and movement during exercise. It comes with a spare set of temple arms so I can match them with my bike and outfit.
In short, AMO Shield is durable, light weight, does not slip, no steam, adjustable nosepiece, changeable temple arms, no frame to obstruct vision, distortion-free vision and with plenty of coverage. I strongly recommend it!
