Main materials: These ski goggles are made of a durable TPU frame and highly impact resistant PC lenses. PC hardened mirrors with curved design resist friction and give you an open and clear view. Effectively blocks harmful light and glare and protects against UV rays, protecting your eyes at critical times and reducing the risk of light interruption. Safety: The elastic headband is adjustable and does not don't slip. You can loosen or tighten the straps to adjust the size, fit and comfort. Both men and women can wear them. Weighing only 120 grams, these lightweight goggles fit snugly over the face and around the eyes, blocking any wind and protecting the eyes from water or dust. These motorcycle goggles can be worn over a helmet. Cut : 18.5*18 cm. Flexibility and UV protection: the TPU frame is equipped with acetate lenses that allow the frame to bend almost 90. It is therefore difficult to compress the glasses and damage them. The lenses are also UV protected, which provides better protection against UV damage and prevents associated eye diseases. The distribution of round holes around the lenses facilitates the circulation of air inside and acts as a certain anti-clogging. Thick Foam: The goggles have a comfortable foam cushion inside, a 0.6 inch thick piece of foam. Although there is only one layer, it is more flexible than multi-layer foam and its thickness is comparable to that of multi-layer foam. Even in winter, it keeps wind and snow out and provides warmth for you and your loved ones. Applications: Can be used for outdoor activities such as cycling, riding, camping, skiing, climbing, fishing, hunting, jogging, motorcycling, tennis, etc. Suitable for men, women, children, teenagers and adults.
