FINIS created and patented the first ever center-mount snorkel designed specifically for swimmers. The Original Swimmer’s Snorkel allows swimmers to focus on stroke technique without the interruption of turning your head to breathe. By eliminating the need to breathe, swimmers can relax in the water, maintain body alignment and improve stroke efficiency. The one-way purge valve allows water to flow out of the snorkel without entering the mouthpiece. Accommodates a full range of motion for butterfly, breaststroke and freestyle.
