The Iguana Dry is a lightweight and reliable choice for young snorkelers. It is a dry-top snorkel with a special valve that closes the breathing tube when submerged, reducing water entry. The lower purge valve allows water to be quickly expelled. The mouthpiece is made of soft and hypoallergenic silicone to ensure comfort and ease of use. The Iguana Dry features a quick-release mask strap keeper, allowing you to attach your snorkel to its mask quickly.
