Product Description The Sideview II Mask and Snorkel Combo opens up the majesty of the underwater world. The Sideview LX snorkeling mask extends your panoramic range of vision to a full 180° so you can experience all the sea has to offer. Easily adjustable buckles keep your mask firmly in place, while a soft, silicone skirt provides a comfortable seal against water leaks. The Astros DX snorkel features a comfortable silicone mouthpiece and a flex section that relieves mouth and jaw fatigue. The Dry Top technology prevents water from entering the snorkel on short dives below the surface for closer explorations. The Sideview LX Combo is a workhorse kit you'll enjoy having with you on your next snorkeling adventure.
