Decathlon’s AQUARESIST swimwear line is specifically designed for regular and intensive pool sessions, offering unmatched durability and comfort. At the heart of this innovation is XLANCE® fiber, chosen for its exceptional chlorine resistance and two-way elasticity. By replacing elastane with elastolefin, XLANCE® ensures the fabric retains its shape, dries quickly, and keeps colors vibrant—even after extended use in chlorinated water.

This makes XLANCE® the perfect choice for AQUARESIST swimwear, guaranteeing long-lasting performance and optimal comfort for swimmers who demand the best from their gear. Whether you're perfecting your strokes or pushing your limits, this swimwear stays in place and keeps up with your pace.
