Constructed from the popular, ultra durable Endurance + fabric—a Speedo exclusive; the Solid Flyback Training suit is chlorine-resistant up to 20 times longer than conventional suits. The thin straps are reinforced with overlap binding for increased durability, while the unique 4-Way Stretch resists stretching and sagging, providing superior shape retention and comfort. The Flyback is a great training suit, intended for regular use.
