The Leakproof Sleep Short of My Dreams

February 22, 2019
Katherine Flemming

I used to have it all figured out. 

Shower. Midol. Light a candle. GIANT overnight pad. Thin black cotton bicycle short (before Kim K made them cool, guys). Then, if I was feeling cold, I would layer on a topper: a fleece leopard-print pyjama pant. In the summer, a stretched out pair of jersey leggings—neither one dug into my waist, which prevented the scorpion that terrorized my uterus (or as some people call them, menstrual cramps) from further torturing me.

If heaven forbid, my trusty shorts were missing—OH MY GOD. My period would be so much more horrific, my sleep interrupted, my frustration peaked, my life ruined, basically. So I'm sure you can understand why I held onto those shorts for a very long time. And yes Marie Kondo, if you can't tell by now: they did spark joy.

SO you can imagine my UNRELENTING JOY when the the design team at Knix asked me to test out the Dream Short. I couldn't wait to get the product on, and get to sleep. They slayed my beloved cotton bike shorts in every single way. I wear tested the product for months, even without getting my period—and became obsessed. Here's why:

1. They are freakishly lightweight. Our design director, Jules Power, told me that the fabric was breathable and lightweight, but I didn't fully understand it until I wore them during an unseasonable warm night when I was feeling under the weather (read: sweaty) and still kept cool.

2. The pad is a legit size: Think of those really long pads that work for overnight purposes or even taller people—that's about the size you're working with when you're wearing the sleep short. The beauty is that, when you're sleeping, leaks are on the loose, so the extra inches in the width and length ensures you're covered from all angles, whether you're a really still sleeper, or one of those tornado types.

3. It's for sleep, but it works for day, too. I've worn these shorts to work. Under jeans, under leggings around the house. You cannot see them. I swear! They're just as seamless as the edges of the Knix underwear, thanks to the bonded technology and four-way stretch.

4. It doesn't dig into your tender spots. Just like my aforementioned cotton shorts, there was major attention paid to the design and construction of the Dream Short. The entire piece is seamfree, and the waistband is soft-bonded, meaning it keeps you held in but doesn't dig into skin. 

5. You can avoid all of the aforementioned drama and production that I listed at the beginning of the story. You're welcome. 

BRB, going to order 5 more Dream Shorts.

Our Leakproof period underwear features triple layer technology that ensures you stay fresh, dry, and protected. The anti-odor top layer wicks away moisture from your skin; the inner-layer absorbs the liquid and locks it in; and the leak resistant outer layer keeps any liquid from spotting your clothes.

Depending on the size and style of underwear, the leakproof gusset ranges from around 7.5" to 9" long. Our Super Leakproof Underwear features a 25% bigger gusset, with more of the coverage in the front of the underwear. For overnight leakproof protection, our Super Leakproof Dream Short gusset ranges from 10" to 14" long.

Our Leakproof Period Underwear feature barely-there built-in panty liners that can absorb between 1 and 8 tampons worth of liquid, providing you with confident protection against period leaks, light bladder leaks, and sweat.

Our Essential Underwear feature a moisture-wicking breathable gusset that keeps sweat and odor away, but they do not provide any leakproof protection.

Depending on the level of absorbency of Leakproof period underwear you choose and the heaviness of your flow, you can wear our period panties on their own or as backup protection along with a menstrual cup or tampon. 


You're totally protected with our high and super absorbency Leakproof underwear, while our low and medium absorbency Leakproof underwear can replace pads and tampons on lighter days and work great as a backup for your usual period protection on heavier days.

Yes! Our period underwear is also the perfect protection against light bladder leaks (LBL). In fact, it was the frustrations and unnecessary stress of postpartum leaking that inspired our CEO Joanna to make her first pair of Knix. 


If you're one of the 1-in-4 women who experience light bladder leaks, our incontinence underwear are here for you. They absorb up to 8 tsp of liquid and feature a moisture-wicking, anti-odor, and bacteriostatic properties to keep you feeling fresh, dry, and confident.
