Atomic SV2 Snorkel The sv2 design has a conical flared top to deliver maximum airflow The lower section enable water to be easily expelled Any water trapped below the mouthpiece is easily cleared with a small burst of exhaled air SV2 Flex: High-Performance Design with a Semi-Dry Top The SV2 includes a Scupper Valve lower section with a sleek semi-dry top. The SV2 semi-dry top employs horizontal vents engineered to diffuse splashed water that would normally freely enter the snorkel top. The small gaps between the vanes of the vent restrict water speed and droplet size and permit most of the splashed water to exit the special vents without entering the breathing tube. The end result is less water in your snorkel. The SV2 is perfect for rough or choppy water conditions.
