One-piece glass design allows a better and wider view underwater, your children can fully enjoy the underwater world and have even more fun in the water. ●Soft nose cover: childrens diving goggles come with a nose cover. The soft silicone nose ensures a waterproof seal of the face when snorkelling, swimming or diving. This feature is especially helpful for children learning to swim and those who do not know how to stop breathing under water through their nose. This childrens snorkel mask is perfect for swimming, snorkelling and freediving. ●Soft and comfortable: it is very important to have a comfortable fit. The diving mask with nose cover for children aged 4-14 years is equipped with a large, soft silicone edge that gently adapts to the childs face and reduces eye pressure caused by long wearing the nose glasses by increasing the contact surface with the skin. Reduces discomfort and red spots when wearing snorkel goggles. ●Easy adjustable headband: the side button buckle is very easy for children to adjust and keeps the band securely in place without slipping down in the water. The silicone apron ensures that the face is fully absorbed, so you dont have to worry about water leakage.
