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!

Great investment

This is my first period using these and they’re great. The sizing was spot on and they fit well. I like the high rise. With the boost in, this made me realize that tampons can make it seem like your flow is a lot more than it actually is. Saving so much waste by switching to these.

So comfortable and do the job!

They are incredibly comfortable, flattering and don't feel bulky. They do the job and have helped me feel comfortable through a tough time.
