Enhanced Child Safety The safety lock combined with a connected lock provides reliable prevention of water accidents during swimming practice, helping keep children safe. On-the-move safety Non-slip surfaces increase handheld friction for a stable grip, enhancing control and safety during kicking and steering. Adjustable buoyancy Three-layer modular board allows you to adjust buoyancy. Removable and reassembled easily to suit different learning stages of infant swimming, ensuring progressive support. Comfortable, skin-friendly fit A balance of resilient construction and skin-friendly material yields a soft, gentle contour for safe, enjoyable play for children at all activity levels. Use scenarios - Early learning in shallow water: Use with adult supervision to practice buoyancy, kicking, and basic propulsion while gradually adjusting buoyancy as the child grows more confident. - Tailored class sessions: In a supervised swim class, customize buoyancy for each child to match their progress, moving from higher to lower buoyancy as skills develop. - Home pool play: Adjust buoyancy for children at different learning stages to enable safe, independent exploration during family swim time. Key attributes - Function: safety lock system and adjustable buoyancy for controlled practice. - Compatibility: suitable for infant swimming lessons and family pool use. - Material: skin-friendly, soft yet resilient construction. - Performance: secure grip with non-slip surface, stable handling, progressive support through buoyancy adjustment.
