High elasticity silicone sealing ring: made of soft PVC material, 3D fitting around the eye contour, waterproof and leak proof, buffering and reducing pressure without pressing the eyes or leaving marks.
Adjustable dual headband: disperses pressure more stably, with a single-sided adjustable buckle design that accurately adapts to different head circumferences, without slipping or loosening during exercise.
Long term anti fog: The inner side of the lens has been upgraded with anti fog technology to avoid condensation of water vapor. Even long-term swimming can maintain clear vision and say goodbye to fog troubles.
