How Do I Know if I'm Wearing the Right Period Underwear?

In a world of ever-expanding options for people who menstruate, you’ve likely heard of Period Underwear — especially if you’re familiar with Knix. 

But you might still have some lingering questions, like how do Leakproof Underwear work? Can they be used as a substitute for other period products, or do they just provide back up protection? Are they just for periods, or can they be used for other leaks, too? 

Since Leakproof Underwear come in a variety of styles and levels of absorbency, the first step is figuring out what your needs are. Whether you’re looking for overnight period protection, to safeguard against bladder leaks, or the freedom to get extra sweaty during your next workout, we’ve got just the thing.

Leakproof Underwear come in an assortment of fits and styles, but what remains consistent across the board is the ultra-technical fabric. 

Leakproof undies feel as comfy and seamless as regular underwear — there’s no bulking, we promise — Now let’s dive in and find your perfect fit.  

Lighter Leaks

Leakproof Underwear are a great option for lighter period days or as backup protection on heavier days when you’re using a Diva Cup or tampon. The same applies to light bladder leaks and sweat. 

The gusset on regular Leakproof Underwear tends to be smaller — especially when it comes to the thong style. So, if you’re planning on sitting for long stretches of time, you may want to consider a higher absorbency option with a larger gusset. Alternately, you can always do a mid-day underwear swap. 

When it comes to finding your preferred style and fit, there’s no shortage of options to choose from. Who said leaks can’t be sexy? Our Knixy Lace Leakproof aren’t your grandma’s underwear. Striking the perfect balance of lacy and comfy, this ornate style comes in all our classic fits.

Our Standard Leakproof Underwear are seamless (no panty lines!), machine-washable, and come in an assortment of fleshy nude tones, pastels, and fun prints. 

Heavier Days

We’ve all been there: waking up only to find unwelcome (and really hard to get out) stains on our sheets. And, let’s face it, sleeping with a pad also isn’t ideal. That’s where our Super Leakproof Underwear come in for full, sleep-like-a-baby protection. 

While our Leakproof Underwear work like a charm for lighter days, Super Leakproof can be worn any day (or night) of your cycle. The extended gusset on these babies absorb blood, sweat, or pee and are ideal for days when you need solo protection, will be sitting for long periods of time, or want to spare your precious sheets from overnight leaks. The extended front gusset on these underwear also make them especially ideal for bladder leaks. 

Zones+ Ultra Leakproof is the latest period underwear to hit the scene. After a decade of spearheading the Leakproof category, the latest innovation is our most absorbent yet. 

Designed using patented Zones+ technology, the undies include coverage zones that target heavy leaks. 

Super Coverage

Just when you thought more coverage wasn’t possible, our Cotton Super Leakproof Boxer Brief swoops in featuring our longest gusset ever — extending from the front waistband to the mid-rear. 

These undies were designed for heavy flow days (and nights) and the leakiest of bladders. They’re also made with a Cotton Modal Blend for the softest and stretchiest coverage imaginable. 

Its only rival is our Super Leakproof Dream Short, which is our highest absorbency underwear ever (for now). Its thick waistband keeps the extended gusset in place for a super comfy, seamless feel that stops anything from leaking through.

Plus, its 4-way stretch material relaxes and molds to your body with wear. We mean, is there anything these underwear can’t do?

Postpartum Protection

If you’re expecting or recently had a baby, do yourself a favor and add a pair of CoreLove High Rise Underwear to your cart. These supportive panties feature an extended gusset that provides special protection for light bladder leaks.

Not to mention, its velvet compression bands provide targeted support and stability to your tummy and lower back. In short, these underwear feel like a big hug. Best of all, whichever trimester you’re in, you’ll still feel cute.
