FAQ

How do period underwear 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.

How does the Booster work?

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 period underwear?

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.

Great product, very absorbent!

I bought this pair to wear my first or second day and it worked so well. No leaks all day. They fit snug which makes sense to avoid any leaks. These are such a game changer! Highly recommend.

LOVE these!

These are very well made! I will be ordering more! Except maybe the full boxer. I have an apron belly and the briefs sort of slide down a bit. But I do love the style!

Great

With the insert they absorb a heavy flow. No smell or wet feeling. Super comfortable I would wear them not on my period. Without the insert I would wear at the end of a period, or if I had a lighter one. I am going to buy enough for a week.
