What Makes Super Leakproof Underwear Super?

What came before the Big Bang? What’s inside a black hole? Is time travel possible? How does Knix’s new Super Leakproof Underwear actually work? — these are some of the universe’s biggest questions. And while most of these remain a mystery, one of these questions is super simple to answer.

With some innovation and a little technology, Leakproof Underwear aren’t as big of a mystery as you might think. Let’s break down how they work, what makes them super, and why you’ll be ditching your tampons and pads by your next cycle. 

Then: The Same Old Solutions

For decades, the same old period products have cluttered our bathrooms, bags and office drawers. With tampons entering the menstruation market in the 1940’s, and adhesive pads sticking to the scene since the late 1960’s, innovation in the period department has pretty much stopped. Besides silicone menstrual cups gaining popularity in the 2000’s, there are so few options considering half the world menstruates. 

Now: Innovative New Options 

In 2013, Knix was born from one single, messy truth: that people leak. Whether it was due to postpartum incontinence or menstruation, Knix knew there was something missing from the intimates industry: Leakproof Underwear. Since then, Knix has designed an entire range of body safe, sustainable absorbent undies— protecting on the lightest days to the heaviest nights.

Why is Super Leakproof Super? 

Knix’s Super Leakproof Underwear are the most absorbent period underwear ever. Seriously. Ever. 

Capable of absorbing up to 40 ml of any kind of liquid (period blood, sweat, bladder leaks, you name it), you’ll be able to ditch disposables like pads, tampons, and incontinence products for good. Before you grab your measuring cup from the kitchen, 40 mL is the equivalent hold of 8 regular tampons. We aren’t kidding when we say that you’ll never have to buy another box again.

Available in all the classic Knix silhouettes you know and love— Bikini, Boyshort, Cheeky, High Rise and Thong available in sizes S-XXXXL,  there’s a pair of Super Leakproof undies for everyone. They're even available in our Dream Short with an extra long absorbent area for overnight protection. 

So, How Does Period Underwear Work? 

The secret to the absorbency is all in the layers. To read about how our classic Knix Leakproof works, check out our blog here for all the insider info from our design team. But we know why you’re here. You’re here to find out how the heck does one pair of Super Leakproof Underwear absorb up to 40 mL of liquid?

The Secret is in the Layers 

They must be bulky, you’re thinking. And while that might be the case for other period underwear brands, all of Knix’s Leakproof Undies (including the Dream Short and Super Leakproof) feel like regular underwear and are incredibly lightweight and breathable. 

The layers of technical materials work hard so you don’t have to.

Our Super Leakproof Underwear features triple layer technology that ensures you stay fresh, dry, and protected.

The anti-odor top layer wicks away moisture from your skin using natural seaweed fibre that leaves you feeling dry; the middle-layer absorbs the liquid and locks it in; and the leak resistant outer layer keeps any liquid from spotting your clothes.

Why Should I Switch to Period Underwear? 

Most of us have spent years with the same period routine. Between stocking up on tampons and making sure you always have extra pads lying around for emergencies, it’s time to reduce, reuse and rethink your cycle. 

Help the Planet! 🌎

Over the past few years we’ve all worked hard to eliminate single-use plastics. Between plastic straws, shopping bags and water bottles, we’ve made changes to adopt reusable alternatives. And we can do the same when it comes to our periods too. 

Disposable menstrual products have been filling up landfills since Kotex created the first menstrual pad in 1921. Not only is that a ton of build up, but most pads contain polyethylene plastic on the sticky part of the pad. And most tampons contain a whole bunch of harmful chemicals like chlorine, rayon and dioxin. When these chemicals sit in landfills, they eventually get soaked up by the Earth and cause water and air pollution.

Switching to period underwear during your cycle is an easy way to cut out single-use menstrual plastics like tampon applicators, pads, wrappers and other packaging. On top of that, all of Knix Leakproof Underwear are completely toxic chemical free. We’re committed to being super transparent when it comes to our products, so check out any product page to see what materials Knix uses.
