Kids Snorkel Set for ages 4-8 features a high-elasticity head strap for effective adjustment, increased flexibility, and comfort. The food-grade silicone face skirt molds to fit children's face shapes, is odorless and non-toxic. The ribbed design provides extra support and ensures a water-tight seal with no leaks. Adjust the elastic silicone strap for a snug fit; the improved mask accommodates various face shapes, including those of children aged 4 to 8. The mask includes a soft liquid silicone skirt that reduces facial water pressure and seals well to prevent water leakage. Anti-fog coated tempered glass lenses offer maximum underwater visibility. The advanced lens shape and anti-fog treatment deliver a clear underwater experience, ideal for young users. Note: Avoid dropping or placing heavy objects on the goggles to prevent lens damage. The skirt and mouthpiece are made from food-grade silicone, free from odors. This snorkel gear is gentle on children's skin, helping to prevent irritation, discomfort, or allergic reactions. It is durable, easy to clean, and suitable for long-term use.
