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 Essential period underwear work?

Essential 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 and into the super absorbent core. Our leakproof lining stops leaks in their tracks while maintaining breathability, so you can bleed easy.

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.

How are Essential period underwear different from Boost and Super period underwear?

Essential period underwear are our thinnest, most lightweight option. Made with super-soft, breathable & sustainable fabrics like our other styles, and featuring an ultra-thin, all-in-one gusset design that absorbs 2-4 tampons worth of fluid depending on the cut. Essential period undies are recommended for light to moderate flow.

I have heavy flow. Are these the most absorbent period underwear?

Essential period underwear provide 4+ tampons worth of absorbency for light to moderate flow. For heavy flow options, check out Super period underwear, or adjustable-absorbency Boost period underwear.
