【OTG Compatible & Excellent Compatibility with Helmets】 This ski goggle features an OTG (Over The Glasses) design that allows for comfortable use even when wearing glasses, with ample internal space to accommodate common prescription glasses up to approximately 16cm wide. This reduces pressure on glasses and ensures a clear field of vision. The highly elastic and durable strap has a non-slip silicone backing, ensuring a secure fit even when wearing a helmet. The length can be easily adjusted and the goggles can be detached using the buckle, making them easy to handle even with gloves on. They flexibly adapt to various head sizes, providing a stable fit for a wide range of users. 【High-Performance Spherical Double Lens Design & Clear Vision Support】 The spherical double lens structure provides a wide field of vision, achieving a natural and smooth appearance while minimizing visual distortion. The impact-resistant inner lens is treated with anti-fog and special coatings, and the air gap between the lenses mitigates the temperature difference with the outside air, creating a structure that suppresses fogging. The outer lens has a waterproof coating to reduce snow and ice adhesion, and a scratch-resistant treatment protects the lens from everyday scratches. Furthermore, ventilation ports at the top and bottom efficiently circulate air, releasing warm, moist air while drawing in fresh air, maintaining a comfortable field of vision for extended periods. 【180° Panoramic View & UV Cut for Clear Vision】 The 3D molded wide-angle spherical lens is helmet-compatible and provides a panoramic field of vision exceeding 180°. The expanded peripheral vision makes it easier to check your surroundings while skiing, allowing you to concentrate on your sport with greater peace of mind. Additionally, the optical design minimizes distortion at the edges of the field of view, making it easier to see uneven snow surfaces and distant objects naturally and clearly. The all-weather lens features UV400 protection, reducing glare from strong sunlight and snow reflection, and supporting a comfortable viewing experience. Vision remains stable even in natural light, making extended outdoor activities more comfortable. The product is brand new. The package has damage. Please purchase only if you understand this.
