Rapha's take on the performance shield is getting a new update this season with the introduction of the Arenberg. The frame takes the previous model's rimless design and wraps it in a full frame and gives the lens venting to reduce any potential condensation. The frame also sits flush with the lens so your peripheral isn't obstructed and a snap-lock hinge makes it easier to remove the frames and secure them to your helmet. The lenses are swappable and are made by Carl Zeiss in a variety of options for different riding conditions.
