The CRESSI ALPHA ULTRA DRY snorkel is perfect for freediving or fishing. It has an upper valve with a 100% anti-splash buoy system that seals the tube when it is submerged, preventing the entry of water. The silicone trachea keeps the mouthpiece always correctly positioned and the silicone mouthpiece is anatomical. In addition, it has a special pocket with an elliptical emptying membrane and a two-component strap fixing clip for agile insertion-removal of the tube. Available in various colors.
