Boosts water confidence for kids learning to swim by supporting progressive buoyancy adaptation, improving water balance, and naturally reducing fear through better coordination. Breathable, skinsafe comfort: EVA foam provides secure contact with a soft, nonabrasive feel, paired with a breathable waist strap to keep the belt comfortable during active swim training. Growthfriendly modular design: Removable panels allow tailored buoyancy as children grow and advance their swimming abilities over time. Enhanced safety and stability: Antitip design with balanced buoyancy distribution and elasticity materials delivers secure support across pool and sea environments. Key attributes Function: supports buoyancy and balance during swim training and practice Compatibility: suitable for pool and sea activities Size: growthoriented with removable panels to adjust buoyancy Material: EVA foam for skinsafe contact; elasticity materials for secure support Performance: stable buoyancy, antitip stability, comfortable for extended use Use scenarios Swim lessons in a supervised pool to build kicking, balance, and coordination with buoyancy aid Family pool or backyard pool day for practicing buoyancy and water confidence during active play Calm openwater sessions (lake or sea) with supervision to maintain stability and support during practice
