Swim Core Solid Swim Jammer for Men is made from Nike NX, an incredibly durable,
colorfast fabric that retains its shape through the life of the garment.
Rigorous testing included the equivalent of 500 hours in the water and colorfast
testing in everything from pool water to sea water. That means no matter how
tough the competition, a suit made with Nike NX is even tougher.
