Key benefits Safe, focused swim training: The built-in buoyancy body supports a stable position in the water so users can practice strokes and body alignment without compensating for sinking. Comfortable, all-day wear: Breathable fabric and a soft, skin-friendly EVA construction prevent chafing and keep the belt comfortable during repeated use. Easy, universal fit: The stepless adjustable buckle adapts quickly to different body sizes — suitable for shared use between parents and children or groups with varying measurements. Quick to put on and remove: Lightweight design plus a reliable quick-release buckle make changing fast and simple, saving time during lessons or workouts. What makes it stand out High-quality EVA material: Durable, tear-resistant and waterproof, engineered to withstand regular pool use while remaining gentle on the skin. Targeted buoyancy: The buoyancy elements are positioned to support practice of specific swimming techniques rather than providing uncontrolled lift. Thoughtful ergonomics: Breathable outer material and an adjustable strap system deliver a secure, comfortable fit for a wide range of body shapes and activities.

User guidance Adjust the buckle so the belt sits snugly but comfortably around the waist before entering the water. Use for focused drills (kickboard drills, arm-only laps) or as general support during lessons and fitness classes. Rinse with fresh water after pool use and allow to air dry to preserve material performance.
