Key benefits Trainer-informed design to optimize arm movement and promote correct stroke mechanics. Six grip openings for flexible, accurate hand positioning that support effective hand entry and pull. Builds core and leg strength while providing even buoyancy to improve body balance in the water. Durable, high-elastic EVA material that maintains flexibility and shape, resists tearing, and withstands intensive use by children. What it does and why you need it Improves arm technique: The shape and grip layout are based on coaching principles to reinforce better arm paths and timing in the water. Supports core development: By encouraging correct posture and balanced buoyancy, it helps children engage and strengthen trunk muscles while swimming. Enhances leg propulsion and balance: Even lift across the body helps swimmers refine body alignment and leg drive, making it suitable for technique-focused practice. Key features Six grip openings: Secure, adjustable hand positions that guide proper entry and pull through critical zones of the stroke. Trainer-backed ergonomics: Designed to support correct arm movement and reinforce coaching cues in the pool. Even buoyancy and balance support: Promotes a natural body position for both freestyle (front crawl) and breaststroke. High-elastic EVA construction: Offers optimal bend and form stability, long-lasting tear resistance, and reliable durability for children’s swim training. Compatibility and intended use Designed specifically for children’s swim training. Ideal for freestyle (front crawl) and breaststroke technique drills, individual practice, or coached lessons. Practical use scenarios Swim lesson drills: Use during instructor-led sessions to teach correct hand entry, pull patterns, and body alignment. Technique-focused pool practice: Incorporate into short sets to isolate arm mechanics while maintaining natural buoyancy. Group junior training: Durable enough for repeated, intensive use in swim clubs or school programs. Performance and care Maintains shape and flexibility under repeated use to provide consistent feedback during training. Rinse with fresh water after each session and allow to air dry to preserve material performance and longevity.
