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 period underwear 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!

Comfort and performance

These are the most comfy period panties I own. They also offer the most coverage and protection. Would recommend. I usually wear them to bed as backup to my cup. I went one size up to make them totally non-restrictive.

Wow!

I’ve bought one of each style of period underwear from aisle cause you never know what fits. Most are comfy and these REALLY ABSorRB. The thick waist band is a bit tight so I recommend getting a larger size if you tend to get bloated during your cycle. But they do stay PUT, no sliding pad nothing!

Best period underwear

I’ve been through so many kinds of period underwear and I feel most secure in these ones. They have a long gusset up the front as well as the back and they fit comfortably
