AF-305 C-4 TURQUOISE 【Discontinued Model】 Visible Light Transmittance: 16% / UV Protection Rate: 99% or more [Included Items] Sunglasses Lens cloth Dedicated case and other items shown in the images. I am selling this as I have not had the opportunity to use it after purchase. The "AF-305" is a new AirFly model with a removable front bar that serves as a sweat guard and design accent. By adopting a 7-curve lens, it provides a wider field of view that covers the outer corners of the eyes more than the AF-301, and reduces wind intrusion. By using a new material for the side parts of the lens, this model achieves the best fit in AirFly history. The frame of the "AF-305" uses a softer new composite material than the conventional TR90. The comfort has been improved, and it is a safe material that can be used with peace of mind even by those with allergies. The lens adopts a 7-curve lens, which has a deeper curve than the conventional 6-curve, and conforms to the shape of the face. It prevents wind from entering during sports and provides a better field of view. The side pads, which have been developed with meticulous attention to detail in terms of material, shape, thickness, and hardness, can be easily bent by hand. Adjustment is possible without any problems for women and children. You can move them forward, backward, left, right, up, and down to self-fit to the best position according to your daily condition and face shape.
