The Deep See Dolphin Snorkel Semi-Dry with Purge Valve has all the features of the Dolphin with the added benefit of a semi-dry top tube. The elliptical upper tube and corrugated flex section is more streamlined than conventional snorkels. The Deep See Dolphin Snorkel Semi-Dry with Purge Valve also has a hypo-allergenic mouthpiece for the best in comfort and durability. The large reservoir at the base keeps any residual water out of the breathing path.
This is an AWESOME snorkel. I had one just like it but the mouth piece somehow got lost. (probably while moving furniture.) I bought one like it but it was horrible. So decided to search for the exact model I had and this is it. Only takes a puff of air to clear. And completely clear too. You won't find better for the price.
