The Speedo Boys HyperBoom Splice Aquashort is the ideal choice for young swimmers who demand both style and performance in the pool. The outer fabric is crafted from 80% recycled nylon and 20% elastane (CREORA® HighClo™), forming the high-quality Eco EnduraFlex textile that delivers significantly higher chlorine resistance than standard swimwear fabrics. 4-way stretch ensures unrestricted freedom of movement across every stroke, while the pilling-resistant construction helps the short retain its shape session after session. An internal drawcord allows for an individually tailored fit, and the front modesty panel liner made from 100% recycled polyester provides added comfort and security. With a leg length of 21 cm, this aquashort offers a classic silhouette that performs equally well during intensive swim training and relaxed leisure swimming.
