FAQ

How do your period undies work?

Our specially engineered lining combines super-absorbent Truetex™ technology with a leak-proof lining that absorb 4 tampons worth of fluid. Use the removable booster for an additional 4 tampons of absorbency.

Do Aisle undies contain PFAS?

No detectable levels of PFAS have been found in our underwear, based on a detectable limit of one part per million.

FAQ Image

Do I need to wear a pad or tampon with them?

Nope! Our undies were built to completely replace pads and tampons. They make great backup protection with tampons or menstrual cups, too.

What does the booster do?

Our undies absorb 4 tampons worth of fluid on their own, but if you need a little extra you can add the optional booster for an extra 4 tampons worth. Just tuck the ends into the slits at either end of the gusset.

How do I wash my Aisle undies?

Our undies were made to fit into your regular laundry routine. Just rinse the gusset in cool water before washing in the machine with your regular laundry. Hang to dry where possible - it saves energy and prolongs the life of your undies!

Real problem that seems to be unique to me

There's a slit in the gusset where the booster can be inserted, and this slit pinches me while I walk, which is EXTREMELY uncomfortable. Otherwise, material is super comfortable!

So Far, I'm Impressed!

I used to wear Thinx AirWear but when I found out they might have PFAS I needed a new brand. I primarily tried these based on the reviews and the color options, but I've lucked out in that they're also really comfortable! I use them as a backup to a menstrual cup so I have not tested their full absorption ability, but they work for me. I make use of the gusset insert at the very beginning of my flow and it's not too tricky to insert and stays in place. You may have trouble if you have limited mobility in your hands, though, as you have to feed the insert through a smallish slit so you need finger dexterity.

I do have one complaint: the waistband is nice and thick but when I sit the elastic bunches at my hips, and stays crinkled up like that for the rest of the day unless I manually re-smooth the elastic. It's kind of weird. But, I still really like them and plan to buy more!

My fav period product

I have tried many other period underwear brands, this cut and fit are my far the most comfortable out there! I found other Aisle styles run tight and felt bulky but these were true to size. I’ve got 4 pairs now and can’t wait to afford more! Would love these in a thong style as well, perhaps one day?
