The Cressi Gamma snorkel is a semi-dry snorkel that has a wave guard at the top that minimizes water entry and has a large elliptical exhaust purge valve on the bottom. The Cressi Gamma snorkel has a fully flexible tube and has a quick attachable snorkel keeper that positions perfectly on the tube. The replaceable mouthpiece is made of 100% hypoallergenic silicone.
