Global intimates brand Knix, who we initially fell in love with for their commitment to body inclusivity, made an announcement earlier this week that will forever change the feminine hygiene industry.

Long gone are the days of trickling an ounce of blue water over a maxi pad; the new Knix Super Leakproof Underwear can hold up to 8 regular tampons (or 40 ml) worth of liquid! It’s an innovation that will not only make periods, or incontinence, easier for womxn worldwide, but will significantly reduce the waste of menstruation products in our landfills and waterways. (Ever seen how many tampon applicators wash up on a beach? Yuck!). 

“On average, women use between 5,000 and 15,000 disposable period products throughout their lifetime. Super Leakproof has the potential to eliminate this undue waste and flip the $35.4 billion dollar feminine hygiene market on its head,” says CEO & Founder, Joanna Griffiths. “It’s time for women to say goodbye to disposable products, without sacrificing sustainability for reliability.”

To drive this point home, Knix took over a garbage truck in NYC and customized it with the message, “Stop trashing your period” for all to see, visiting iconic NYC landmarks including Times Square and the Brooklyn Bridge.”

Super Leakproof is lightweight, thin and available in a variety of styles and inclusive sizes ranging from S – XXXL, and is also available in the brand’s teen line, KT by Knix. For more info, head to
