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 that fits snugly against the face, effectively preventing water leakage while reducing pressure on the skin around the eyes. It is unlikely to leave marks even after prolonged use. The adjustable elastic strap can be quickly adjusted to the appropriate tightness according to different head shapes and wearing preferences, ensuring stability and comfort.
