Speedo Butterfly Back

The Speedo Hyperboom Butterfly Back 1p swimsuit in black is a performance swimwear designed for serious swimming activities. This one-piece suit features a butterfly back design that offers optimal shoulder mobility and freedom of movement during strokes, making it suitable for training, lap swimming, and water aerobics. Made from Speedo's durable Endurance+ fabric, this material is chlorine-resistant and retains its shape and color intensity with long-term use, designed to last longer than conventional swimwear materials. The black color provides a classic, professional appearance while offering UV protection. The suit ensures a secure fit with adjustable straps and a lined front for comfort and coverage. The design incorporates elements of Speedo's Fastskin technology for reduced water resistance, although it is a training suit and not a competition model. The suit is available in size 40, corresponding to standard European women's sizes. Care instructions recommend rinsing with fresh water after each use and avoiding machine washing with harsh detergents to maintain the fabric properties. This swimsuit is designed for adult female users, based on its cut, sizes, and design features.
