How Do Period Underwear Work?
How Do Period Underwear Work?
Period/leakproof underwear works by using a combination of absorbent and waterproof layers to trap and lock in menstrual flow. The top layer wicks away moisture and keeps you dry, while the inner layers absorb liquid and the leakproof layer prevents leaks. Designed for comfort and performance, Aisle period underwear can be worn alone or as backup for other period products.

FAQ
How do Super period underwear work?
Super period underwear feature three types of fabric technology to keep you dry and comfy all day long.
The moisture wicking top layer draws fluid away from the skin, the dual-layer absorbent core soaks up 8+ tampons worth of fluid, and leakproof lining stops leaks in their tracks while maintaining breathability, so you can bleed easy.
The Super Boxer also features a maximum-coverage leakproof lining, that extends from front to back and down the inner thigh to catch side leaks.
Do your period underwear contain PFAS?
We do not add PFAS to any of our products. In addition to using OEKO-TEX certified materials, which are tested for the presence of PFAS, we also conduct additional third-party tests. No detectable levels of PFAS have been found in our underwear, based on a detectable limit of one part per million.
Do I need to wear a pad or tampon with Super period underwear?
Super period underwear provide 8+ tampons worth of absorbency and can be worn on their own, without a disposable pad or tampon.
I have heavy flow. Are these the most absorbent period underwear?
Super period underwear are our most absorbent option. Featuring an all-in-one gusset design with a dual-layer of targeted absorbency that holds 8+ tampons worth of fluid. The Super Boxer also features a leakproof layer that extends from front to back and down the inner thigh.
i have super heavy periods and have ruined so many pairs of underwear leaking overnight. these are LIFE-CHANGING!!! they’re comfortable and felt really secure. most importantly, there was not a single droplet of blood on my sheets after wearing them on my heaviest night. i bleed on my sheets more often than not on my period. + i always sleep horribly trying to keep the pad in place, but with this underwear i slept starfish and had the best night of sleep i’ve ever had on my period. 100% worth it, i immediately bought two more pairs.
Liked everything about them but I should have ordered the small instead of the medium
