Cressi Kids Snorkeling Equipment for Snorkeling and Swimming | Rocks Combo The Rocks Kids Combo is Cressi's answer to the price conscious parents who need reliable snorkel equipment for their kids for vacation use. We offer the solution for adventurous kids who need decent quality for all day use in the pool or in the ocean. The Brisa is a kids' snorkeling mask with ultra-clear tempered lenses and a skirt made of hypoallergenic soft liquid silicone. The frame is constructed from techno-polymer for added strength and durability. The lenses have a shape that allows a wide view of the side and downwards. They are made of tempered glass like the professional scuba diving mask. It is suggested to use an anti-fog solution for cleaning the lenses before use. Thanks to the buckle design it is very easy to adjust the mask strap length. The double strap allows to the mask in place on the head without being necessary to tighten it too much. The Rio is a semi-dry top design snorkel ideal for kids that want to enjoy snorkeling taking every breath with confidence and not on worrying about water in your airway. The profiled splash guard significantly reduces water entry.
