The Beta semi-dry snorkel from Cressi has a large-bore tube that allows lots of airflow while you’re enjoying the scenery just below the surface. The profiled splash guard deflects water away from the top of the tube when swimming in choppy seas; water that does manage to find its way in is easily expelled through the lower purge valve. A flexible tube section lets the silicone mouthpiece hang out of the way when scuba diving. Cressi’s Sigma snorkel is a smaller version of the Beta, making it easy to pack for dive travel. It too has an upper splash guard plus a clever drainage well below the mouthpiece that collects water so it won’t interfere with breathing. Both snorkels come with clips for securing to a mask and are available in a range of colors.
