Free divers, snorkelers, and scuba divers will all benefit from the Mares Marlin Mask Snorkel Combo. The low internal volume allows the mask to fit closer to the face, making them easier to clear while providing a larger range of vision. This large range of vision is perfect for scuba divers and snorkelers. Rapid action buckles can be adjusted to your head while the silicone skirt ensures a water-tight seal around your face . . . . . . . . . . Whether you're exploring for fun or working on perfecting your stroke, the Mares Sailor Splash Semi-Dry Snorkel is ready to hit the water. This silicone snorkel features a semi-dry top that helps keep water from splashing into the breathing tube. The comfort bite mouthpiece is designed for comfort, while the swivel snorkel keeper keeps your snorkel in place without dragging down your mask strap.
