When you are out snorkeling and want to surface dive to look at something that has caught your eye up close this dry snorkel seals out water when submerged. Once you return to the surface there is no need to blow into the snorkel to remove water because the dry valve kept it out of the breathing tube. The mouthpiece fits comfortably in your mouth for hours of snorkeling fun. The silicone mouthpiece is also replaceable and can be removed easily when replacement is necessary. The flexible lower tube makes the snorkel perfect for Scuba by automatically swing out of the way when you are using your scuba regulator.
