A great training suit, the Solid Jammer Endurance+ from Speedo is constructed from the exclusive Endurance + fabric, Speedo's most durable and popular material. Chlorine-resistant, the Endurance+ lasts up to 20 times longer than conventional swimwear fabrics. Moreover, 4-Way Stretch technology keeps it from sagging and bagging, ensuring a comfortable, body-hugging fit for longer. The jammer style offers more leg coverage, featuring a front gusset and inner drawstring at the waist for a secure fit. It is the ideal suit for training and regular use.
