[180 HD Vision] kids goggles 3-15 are designed with one-piece lens, providing children with a panoramic clear view, embracing the wonderful underwater world with their eyes (suitable for indoor and outdoor swimming), giving children a full sense of security, making swimming more fun and parents more at ease. [Comfortable Silicone Gasket] Benefit from the single-lens design, these goggles for kids 6-14 do not exert too much pressure on the kid's eye sockets. The wide silicone gasket not only provides a strong watertight seal and ensures no leaks, but also distributes the pressure of the kids swim goggles on the eyes, so they can be worn for long periods without discomfort. [Anti-fog] The inner surface of the goggles for kids 3-6 uses an advanced anti-fog technology to form an anti-fog coating inside the mirror, which can quickly disperses water mist and prevents it from condensing, giving your child a clearer and more transparent visual experience. (Tip: To protect the anti-fog layer, please do not wipe the inner surface of the mirror directly with your fingers or other objects) [No Nosebridge Design] Compared to toddler goggles that are attached by a nosebridge, our kids goggles for swimming 4-7 are formed in one piece for greater stability, and there is no risk of the nosebridge breaking or scratching the bridge of the child's nose, safer to use.
