As a teen, I understood the power of having an extra dark sweatshirt in my backpack. Whether my period took me by surprise, or my flow was unexpectedly more, uh, flow-y, having a sweatshirt I could tie around my waist until I could get my hands on a) a new pad, and b) fresh jeans, was infinitely clutch. Back in the day (lol—the early 2000s), I didn’t have the option of period underwear to ensure I could be leak-free for hours. Now? Brands like KT (Knix’s little sister brand) exist so teens don’t have to carry an old sweatshirt in their backpacks just in case.

If you or your teen are new to period underwear, know that it can be worn in two ways (coming from someone who has several pairs!): You can wear period undies with a tampon or pad for extra security, or you can wear the underwear by itself. Period underwear can absorb as much as a tampon or pad can, and is constructed from a type of fabric that helps you feel dry and fresh—even on your heaviest days.

The Super Leakproof underwear absorbs three super tampons’ worth of blood while wicking away moisture so you don’t feel damp (the worst). The material is ultra soft and stretchy, which is much-appreciated when you’re already dealing with cramps and bloating, and unlike a lot of period panties out there on the market, these are *actually* no-show.

“My daughter loves the fit of these. The absorbency area is the right length and she loves that they’re no-show. Many times repeat buyer!” one shopper confirms.

One shopper shares that her daughter wore this underwear to her gymnastics meet in her leotard: “My daughter was able make it through a three-hour gymnastics meet without needing to go to the bathroom worried about a leak! Prancing around in her skimpy leotard worry free! No leaks and couldn’t tell she was wearing underwear! LOVE these!”

Other KT best-sellers include the Super Leakproof Sleepover Short ($39) for heavy days, Light Leakproof No-Show Bikini Underwear ($19) for lighter days, and more.
