Frequently Asked Questions

Q: Can I use this swim buoy float in both pools and open water?

A: Absolutely! The Shunmaii swim buoy float is designed for versatile water use — it works great in swimming pools, lakes, rivers, oceans, and any other body of water. The bright color also keeps you visible to boats and other swimmers in open-water environments.

Q: How do I switch between using it as a buoy and a water weight bag?

A: Simply use the dual-function valve — inflate it with air for maximum buoyancy and attach it via the waist belt for swimming. To use it as a water weight bag for anchoring tents or umbrellas, drain the air and fill it with water instead. The transition takes just a minute or two.

Q: Is the waist belt adjustable to fit different body sizes?

A: Yes! The included waist belt is fully adjustable, making it suitable for a wide range of body sizes, from children to adults (unisex). It provides a snug, secure fit so the buoy stays in place during active swimming.

Q: How durable is the PVC material in saltwater environments?

A: The PVC construction is waterproof and resistant to both fresh water and saltwater. We recommend rinsing the bag with fresh water after saltwater use and storing it deflated in a cool, dry place to extend its lifespan.
