Nike has developed a new 3D-printed sports bra called the FlyWeb Bra for runner Faith Kipyegon’s attempt to break the 4-minute mile barrier. The bra is made from a 3D-printed TPU (thermoplastic polyurethane) material designed to manage moisture better than traditional textiles. The racerback design provides increased range of motion while featuring a computationally designed surface with varying density for targeted support.
The FlyWeb Bra was created as part of a complete performance kit that includes a specialized speed suit and lightweight spike shoe. According to Nike, typical sports bras can create thermal burden and retain moisture against the body, which can impact performance even in shorter events like the mile. This new approach aims to address these limitations.
Kipyegon began testing the bra earlier this spring. “I’ve never worn something like this in my life. I love it,” she reportedly told the Nike team after her experience with the product. The bra was custom-made for her specific needs and body measurements.
“This 3D-printed material innovation represents something entirely new on a visual and visceral level,” says Janett Nichol, VP, Nike Apparel Innovation. “Sports bras have never looked or felt like this before. The material is soft, light and incredibly supportive — yet it also feels like you’re not wearing anything at all.”
The FlyWeb Bra demonstrates how 3D printing technology continues to find applications in performance sportswear. While this particular item appears to be a one-off creation for an elite athlete, it highlights potential future directions for sports apparel manufacturing using additive technologies. Nike has not indicated whether similar 3D-printed products will become commercially available.
