【Unique frame design for a wide field of view】The iTOWE kids swim mask have a wider frame than typical children's goggles, providing extra space for a wider angle of view. Children can observe their surroundings with a 180-degree view without needing to move their heads much. Additionally, the goggles have a smaller internal space, meaning the eyes are closer to the lenses, which broadens the field of vision. 【Clear 180° Panoramic Tempered Glass View】The iTOWE goggles for kids diving mask are equipped with tempered glass for excellent transparency and clear visibility. Underwater views appear as crisp and close-up as if seen directly, without any blurriness, distortion, or loss of true image. When children leave something at the bottom of the pool, they can dive in with these swim goggles to look for it, which they find very exciting. 【Multi-angle adjustment for comfort and fit】Unlike typical diving goggles, this children's model features adjustable side buckles that can be moved up, down, left, and right. This means they can comfortably fit any child's face, whether it's round or slim, and any face shape. By pressing the side buckle, the strap length can be adjusted, ensuring a perfect fit for any head size or shape. When your kids wear these goggles, they experience comfort without tightness, no leakage, and no discomfort. 【Double-layer thick silicone seal & nose cover seal for leak prevention】These kids snorkel mask feature a silicone pad with memory function, which adapts to a child's face shape for a perfect fit after being worn a few times. The double-layer silicone and nose cover ensure a tight seal to keep water out, protecting eyes from chlorine and bacteria. The silicone suction is also appropriately gentle, ensuring that even after hours of swimming, there are no red marks around the eyes and nose. 【Cartoon Curve Design, Suitable for 3 - 16 Years Old】This lovely children's swim mask is available in two sizes: Small S is designed for children aged 3-10, and Large L is designed for children aged 8-16. It has a cute cartoon curvy look and is available in a variety of colours that kids will love. If you have any questions after receiving the product, please don't hesitate to contact us.
