【Spherical Lens & Wide Field of View】 These goggles feature a rounded, arched design, providing a wide field of view both vertically and horizontally. The 180-degree ultra-wide-angle view allows you to clearly see the surrounding terrain, allowing you to fully enjoy winter sports. ★ Package Contents: Ski Goggle Body x 1, Storage Case x 1, Storage Bag x 1, Instruction Manual x 1 【Double Lens, UV400 Cut, UV Protection】 The double-lens structure consists of an anti-fog lens on the inside and a UV-cut lens on the outside. This design provides clear vision while protecting your eyes from harmful light with its high UV400 cut function. The spherical lens is treated with UV-cut processing, guarding your eyes from light reflection and enhancing visibility. With a UV cut rate of 99.9% or more, it protects your eyes and skin even on sunny days. 【Ventilation Processing & Anti-Fog Specifications】 Ventilation is installed at the top and bottom of the lens, expelling moisture and heat from inside the lens, bringing in fresh air, and preventing stuffiness even on humid days or when sweating. In addition to the double lens, which reduces the temperature difference between the inside and outside, ventilation ports in the frame circulate outside air to prevent fogging. 【3-Layer Sponge & Impact Resistance】 The soft, high-density 3-layer sponge fits snugly against the face, protecting the eyes from water, dirt, snow, and wind. The frame uses a soft and flexible TPU material, achieving excellent impact resistance. It also helps protect your eyes in the event of collisions or falls. Windproof and impact-resistant, it is ideal for outdoor activities such as skiing and snowboarding. This model allows for easy lens replacement, so you can quickly adapt to the changing weather conditions in the mountains, making it perfect for those who frequently change lenses depending on the weather and time of day. 【OTG Compatible & Helmet Compatible】 The volume inside the goggles is larger than ordinary goggles, so they can be worn comfortably even with glasses. However, there may be limitations on the size of the glasses, so please check in advance. ★ Maximum glasses size: Length 15cm x Width 5cm. The long strap is compatible with various helmet shapes and reduces slippage when wearing goggles.
