This Snorkeling set features quality equipment by on of the leaders in the industry. The Viper fins have a flexible center power thrust channel which directs water off the tip of the blade for improved power and efficiency and engineered side panels and rails which directs the water flow and minimizes spill off the sides of the fin. An ideal fin for all snorkeling levels. Oceanic's sunset boots use 3mm uppers which are double glued and blindstitched for durability and attached to a slip resistant flexible sole for ultimate comfort. One the other end the is a 4 window tempered glass Prizm mask with an excellent panoramic view. The soft silicone skirt has a double seal to fit a wider variety of faces. The Ultra Dry snorkel is the best thing since sliced bread. Oceanic's patented Dry Snorkel Technology makes it the driest snorkel you will ever use. When using it, if your snorkel drops below the suface of the water it closes BEFORE the water can enter. Add to this a soft silicone mouthpiece that is replaceable and you have a set that not only looks good but is very user friendly.
