Dive in with your child using Seavenger s Hanalei 3-Piece Snorkel Set. It includes a tempered glass twin lens mask with durable anti-fog film, a flexible snorkel with a hypoallergenic mouthpiece, and a 16x8" mesh bag. The anti-fog lens provides crystal-clear views, better than traditional coatings. The soft nose pocket and low-volume design make equalizing easy, and the swivel straps offer an adjustable, secure fit for all snorkelers.
