I just found this company and couldn’t be more thrilled. I love the fabric and fit of this thong and as someone who deals with bladder issues from Dysautonomia, these are my new go to. Please bring back the tan, I would like to buy more.
I am sooo happy that this was brought back, one of the best thongs I’ve ever owned! They fit comfortably and are amazing for those light days
soft, breathable, true to size…. all the primese are true
Love this product
replacing all my old undies with aisle
I’m a plus size girlie with an apron belly, and I wear these thongs all month long! They absorb enough to handle a normal period day, and are also great for keeping me comfortable on sweaty summer days. The cut of the hips and waist is much more comfortable than a typical thong. 10/10.
I love my thongs! I am inbetween small and medium, I went for medium ones because I have bigger legs and booty and it fits perfectly. I'm 5'3" and 135lb for the reference. Compared to the period company's period thongs, not only aisle's period thongs are made from better material, it also has longer absorbent part to the back. Love love love.
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 Aisle undies 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 Essential period underwear?
No need to double up for light days and minor leaks, but we do recommend pairing your thong with a cup or tampon for moderate-heavy periods.
Can I wear the Essential Thong for heavy flow?
Essential Thongs can absorb one tampon worth of flow. We recommend using them on light flow days, during workouts, or as back-up to a tampon or menstrual cup. For heavy flow options, check out Super period underwear, or adjustable-absorbency Boost period underwear.
