Patented design helps keep your snorkel free of water.
• When submerging under the water, a small buoy inside the Dry-Top rises, effectively sealing the tube.
• Thus water is prevented from entering, keeping your snorkel completely dry!
• When you surface, the buoy drops, opening the air passage for maximum airflow.
For use on FINIS Swimmer's Snorkels only.
Note that using the Snorkel Dry Top will slightly restrict air-flow into the tube. The Dry-Top attachment is recommended for experienced users.
