100% Silicone gasket 70% Polyester / 30% Spandex body

Hydro gasket with elastomer silicone creates a seal around the athlete's form, allowing maximum range of motion while preventing water entry at crucial fit areas.

Zoned tension technology prevents air and water pockets resulting from poor fit by eliminating seams and providing areas of restricted stretch that force the suit to fit the form perfectly. Seams are aligned with the fluid flow to minimize drag.

Nike no-sew leg openings and silicone cuffs use a bonded elastic fabric that lies smoothly against the skin to minimize drag and maximize comfort. Cool grey white silicone waistband. AMPD technology
