Nike Leak Protection: Period

$24

Ease your mind with our leak protection underwear. Soft, lightweight fabric flexes as you move while an ultrathin, absorbent liner helps prevent visible period leaks when worn as a backup to your usual protection. So whether your day includes cycling, training or a date with your heating pad, you can take it on without worry.

Work It, Feel Confident

An ultrathin liner absorbs about the same amount as a standard disposable liner—without the bulk.

No Show All Day

A smooth, seamless design stays in place without riding up, digging in or showing lines.

Sweat Ready

Nike Dri-FIT technology moves sweat away from your skin for quicker evaporation, helping you stay dry and comfortable.

Work Hard. Wash Easy.

Care instructions aren't any different than washing your regular workout clothes. Machine wash them with like colors, remove immediately and do not allow them to lay on themselves while wet. Tumble dry low and use a cool iron as needed. No need for dry cleaning, softeners or bleach.

How This Was Made

The recycled polyester used in Nike products begins as recycled plastic bottles, which are cleaned, shredded into flakes and converted into pellets. From there, the pellets are spun into new, high-quality yarn used in our products, delivering peak performance with a lower impact on the environment.
In addition to reducing waste, recycled polyester reduces carbon emissions by up to 30% compared to virgin polyester. Nike diverts an average of 1 billion plastic bottles annually from landfills and waterways.

I have no issues with these leak protection panties on my cycle days, with a T or P on, i don’t have to worry if it does leak through it won’t go past that padding in the panties. They are confused too
