Leakproof Underwear for Every Day of Your Cycle

TEAM KNIX / AUG 26, 2020

There are many words to describe menstruation. Annoying might be one of them. Painful could also come to mind. And if you’re doing some quick math, expensive may also top the list as well.

But Knix views periods a little differently. We think of menstruation as something that can be comfortable. And ultimately we think of it as something that has no place in ruining our day. 

Having a better relationship with your period is easy to do with Leakproof Period Underwear. They’re a sustainable, reusable, and safe alternative to tampons and pads.  Not only do they feel and look like regular undies, but there’s a wide absorbency range that has your butt covered no matter which way you flow. Yes, even on that scary Day 2 (Hello, Super Leakproof!). 

Read on to learn about which of Knix’s Leakproof Period Underwear we recommend for every day of your cycle. 


For Light Flow Days

Hi period! Thought I felt you coming. The beginning and end of your period can be tricky. Your flow is a little too light for a tampon, but pads or liners can feel bulky and wasteful. Undies like the Leakproof Thong, Leakproof High Rise Thong, and Leakproof Lace Thong are perfect for your barely there days. They’re also a great pair of everyday underwear if you sometimes spot during the month, sweat a lot at the gym, or pee a little when you laugh or sneeze (we’ve all been there). These undies absorb about 1 tsp or 5 ml of liquid, which is the equivalent hold of 1 tampon. 


For Medium Flow Days 

Your period is definitely flowing now! Absorbing up to 3 tsp of liquid or 2 tampons, Knix’s medium absorbency undies are available in a variety of styles, like our classic Bikini and Boyshort. These are perfect to wear solo on medium flow days, or for your entire cycle if your flow is typically on the lighter side. They can also be worn as a backup for extra confidence when wearing a menstrual cup.  

For Heavy Flow Days 

This is it. Your dreaded Day 2 and 3. You’ve prepped the hot water bottle and snacks— all you need now is Super Leakproof Underwear. The most absorbent pair of Leakproof Undies on the market, they’re capable of absorbing up to 40 ml of any liquid (period blood, sweat, bladder leaks, you name it). That’s the equivalent of 8 regular tampons. No need to wear a pad, tampon or menstrual cup with these— they can be worn on their own, just like regular underwear. Super Leakproof Undies also have a longer absorbent area in the back and front, for even more protection. A sustainable replacement of disposable period products, Super Leakproof Underwear is ready for even the mightiest crimson wave. Check out how they work here

For Night-time Protection 

We all know that even when we’re off to dreamland, our period can still be wide awake. The Dream Short is a super-comfy sleep short that absorbs up to 4 tsps or 4 tampons worth of liquid. They have an extra long absorbent area that stops leaks no matter which way you toss and turn. Gone are the days of waking up with stained sheets, thanks to the Dream Short. 

Washing Leakproof Undies shouldn't have to be complicated, so we designed our products to be super easy to wash and care for. For best results, machine wash on cold with mild detergent and tumble dry on low. That's it! Pro tips: Don't use softener or bleach, and never machine dry or iron.

Looking to go your next cycle without using any tampons or pads? Knix has you covered with Leakproof Underwear kits designed with your unique cycle in mind. Light, Heavy, or a mix of both, it’s time to ditch disposables and switch to Leakproof for good.
