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!

Transformative!

Comfortable and easy to maintain. I have a very heavy flow and wasn't sure if this would do it. This is my second pair and I can't tell you how much I LOVE it and how transformative it has been for me when it comes to dealing with my period. Ideally I would like to have around 10 -15 pairs in my drawers so I never have to worry about leaking or buying more pads and tampons. Thank you aisle team for this incredible product. Once in a while you come across a product that actually does EXACTLY what it says it will do! Thank you. Thank you.

Comfortable and Secure

Full coverage and excellent comfort while providing good absorbency as a backup for a tampon or cup. I noticed when I used these on their own on a heavier-flow day that I did get a little bit of leakage around one of the seams, but fortunately it stopped at the outer layer of the bikini and did not stain my pants. Still, I will continue to use them as a backup for peace of mind, and they're comfortable enough to wear on days when I'm waiting for my period to start and don't want to risk ruining a pair of underwear.
