In April, Nike introduced the One Leak Protection: Period Short, which is available in the Nike One Short silhouette. The shorts feature  Nike Leak Protection: Period, an ultrathin, absorbent liner that helps protect against period leaks, to help expand sport and movement for the next generation, so teens and adults can continue doing what they enjoy with peace of mind.

The proprietary material technology went through significant validation and wear testing, creating a new Nike-innovation-backed solution to provide added protection. Nike designers created and tested more than 30 prototypes to find the just-right fit for movement and comfort.

“Fear of bleed-through is real — and not just through the teen years, but through the entire journey of menstruation,” says Lisa Gibson, Senior Project Manager, Nike Apparel Innovation, and a key player in developing this new innovation. “Nike Leak Protection: Period is for people with periods across all life stages, designed to give them an added layer of confidence so they can feel secure during all forms of sport and movement. It’s an innovation that we believe will change people’s lives.”
