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!

Brief

Soft - comfortable- PFAS free - worked great. Extra pad is cumbersome, but worth it — comically reminded me of my daughter’s cloth diapers but it’s better than not having it at all!

Love them. Buying more.

So comfortable. Hate disposable and reusable period pads. These have changed my life. I have four pairs of the boost boxers and two of the briefs for my lighter days. Going to grab another couple briefs for posterity!

Good absorbency and comfy

I like this underwear a lot! I just wish the band was a little wider (I love the boxers for that). Would make for a more comfortable fit, as I always feel sensitive around my waist during my moon days.
