The Tread Jammer moulds to your body for a smooth, hydrodynamic, and speedy swim. We’ve also thrown in triangle front lining and a drawstring waist because we couldn’t let you sacrifice comfort for speed when you can fly through the water and feel amazing while doing it. Made from innovative Ecolast™ fabric, composed of recycled ocean materials. Ecolast™ is not only helping protect our environment for future generations, but has also proven itself to be more durable and resilient to chlorine than other generic swimwear fabrics.
