Features: Excellent fog performance: Utilizing advanced anti-fog coating technology, a long-lasting and effective anti-fog layer is applied inside the lens, significantly reducing water condensation. Even in a swimming pool environment with a large temperature difference, it maintains clear vision for a long duration, allowing you to focus on swimming without frequent wiping. Full-angle view and wide field of view: The unique large-frame design, combined with ergonomic curvature, exceeds the limitations of traditional swimming goggles and provides an ultra-wide-angle view of nearly 180 degrees, delivering a panoramic view of the underwater and surrounding environment. Whether observing the swimming lane during pool training or monitoring conditions in open water, it handles both with ease. Comfortable fit: The frame is made of soft medical-grade silicone material, which fits tightly to the face, effectively preventing water leakage while reducing pressure on the skin around the eyes. It is not prone to leaving marks even after extended wear; the adjustable elastic strap can be quickly adjusted to the appropriate tightness according to different head shapes and wearing preferences, ensuring stability and comfort. High-quality and durable material: The entire product is constructed from high-quality materials. The goggles have good impact resistance and are not easily broken, able to withstand accidental collisions during daily use. The lens frame is sturdy and durable, resistant to wear and scratches. Even with frequent use and long-term storage, it maintains excellent performance and appearance.
