Full-angle view and wide field of view: The unique large frame design, with ergonomic curved edges, goes beyond the limitations of traditional swimming goggles and provides an ultra-wide-angle view of nearly 180 degrees, offering a panoramic view of the underwater and surrounding environment. Whether it is observing the swimming lane during pool training or paying attention to conditions in open waters, it can be easily handled. Comfortable fit: The frame is made of soft, medical-grade silicone material, which fits the face tightly, effectively preventing water leakage while reducing pressure on the skin around the eyes. It is not easy to cause marks even when worn for a long time; the adjustable elastic strap can be quickly adjusted to the appropriate tightness according to different head shapes and wearing habits to ensure stability and comfort.
