Review on 🏊 Lap Swimming Snorkel for Adults – Advanced Snorkeling Gear for Training in Pools and Open Water. Center Mount Silicone Mouthpiece with One-Way Purge Valve – FOCEVI Swim Snorkel. by Oscar Berry

This particular whistle was requested as a possible Christmas present for a family member who wants to practice laps at our Y's Swiming. a swimming pool recently converted into a seawater pool. Getting water in her mouth from the spray generated while swimming circles on the adjacent lane, or from her own hand as she turned her face to breathe in air, was much more annoying in the salt water. It is hoped that a backwash snorkel will make swimming more comfortable. I bought one then. Neither of us have had a chance to swim since Christmas, but we're excited to try it.
