When a human body reaches 19 mph, the medium it’s moving through fights back, creating drag and reducing efficiency. That’s why PROJECT SWIFT was created—to maximize performance and minimize the forces that work against you. Nike researchers and product designers teamed up with an elite group of swim coaches, submarine designers, and sports aerodynamicists to study the way water interacts with the human form. Combining years of research, rigorous testing, and feedback from top athletes, Nike’s streamlined suits glide through the water in perfect harmony with a swimmer’s motion. Every fabric and seam placement is scientifically chosen—and proven—to enhance your speed.

1. Hydro Gasket

Elastomer silicone creates a seal around the athlete's form, allowing maximum range of motion while preventing water entry at crucial fit areas: the neckline, armholes, and waist.

2. Zoned Tension

Areas of restricted stretch force the suit to ride against the athlete's body in critical fit areas like the sternum and lower back. This prevents the development of air and water pockets that result from poor fit. Zoned Tension technology allows us to fit the body very closely without the use of seams, which drag in the water and slow the athlete down.

3. Seam Alignments

Wherever possible, seams are aligned with the fluid flow to minimize drag.

4. Nike No Sew

Leg openings and ankle cuffs use a bonded elastic fabric that lies smoothly against the skin to minimize drag and maximize comfort.
