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?

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!

Comfy

I'm a big fan of the whole boost line. Compared to other period undies from other brands, I like the fabric of these way better. Feels more like cotton and less synthetic. My only complaint is that the seams of the leg holes can occasionally irritate my skin.

Good Product

Like that they are seamless on the sides (just wish instead of an insert it had a more absorbent built in)

Sized up and happy

I typically wear a women’s large or unisex/men’s medium but I decided to try sizing up to XL and they’re so much more comfortable around my legs. My regular sizes were pretty tight.

As far as period underwear goes I love aisle. I’ve never leaked, the fabric is very nice.
