Atomic Aquatics SV2 Flex Semi-Dry Snorkel The Atomic Aquatics SV2 Flex is a high-performance snorkel designed for rough or choppy water conditions. Featuring a semi-dry top and Atomic’s proven Scupper Valve (SV) system, the SV2 minimizes water entry while delivering smooth, effortless breathing. Horizontal vents in the semi-dry top are engineered to diffuse splashed water before it enters the breathing tube. By slowing water speed and breaking droplets apart, most splashed water exits through the vents—keeping the snorkel noticeably drier during surface swims.
