Versatile compatibility and adjustable fit: multiple floating modules enable buoyancy belts for both youth and adults, adapting to different body types while providing comfort and stability during water activities. Easy water adjustment for gradual adaptation: supports progressive acclimation to water environments, making it ideal for beginner swimmers; ensures even weight distribution around the torso to help maintain posture and reduce learningrelated strain. Flexible buoyancy configuration: buoyancy standards and module spacing can be modified as needed to meet a range of aquatic training tasks with ease. Durable, comfortable foam construction: elasticity closedcell foam with a soft touch allows safe movement and remains shaped over longterm use in waterresistant conditions, contributing to comfort and stability during swimming. Use scenarios: Swim lessons for children and adults who are to buoyancy training, helping with floatation and balance while learning. Water fitness or rehab sessions that require stable buoyancy and even weight distribution to support gentle movements and cardio work. Technique drills and progression practices in pool workouts, using front or rear module placement and adjustable spacing to target specific balance and posture goals.
