The wave design of the cup provides a large surface area for easy breathing. Moisture is wicked away from the entire mask cup, so glasses and goggles are less likely to fog up and lose their shape due to moisture. It has low air resistance, making it easy to talk while wearing the mask. The design fits your face well and is not easily displaced.
