How do your period undies work?

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!

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

Comfortable

I bought 2 for the heavy days and they work perfectly. Snug in all the right places and I don’t have to worry about leaking.
