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!

Elastic is too tight

I’m disappointed how uncomfortable this product is! My measurements are well within the size that I ordered but the elastic is so tight that I have to roll it down around my hips or else it puts pressure on my stomach and makes me feel sick. I really wanted to love them but they aren’t comfy.

Love these

They fit good, they are light but they can hold a lot. I’m pleasantly surprised and love that there are toxins in this product. I’ve now switched over from Thinx snd will be buying more pairs of these boost briefs.
