FAQ

How do your period undies work?

Aisle undies feature a specially engineered lining that combines super-absorbent Truetex™ technology with a leak-proof lining to keep you dry and feelin’ fly.

How much fluid do they hold?

8X as much as a standard disposable! Our undies absorb 4 tampons worth of fluid on their own, or 8 tampons worth when you wear with the included booster.

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?

It’s not that complicated - our undies were made to fit into your regular laundry routine. Just rinse out in cool water, then wash and dry with your regular laundry. As with any garment, wash with like colors.

Peace of mind

Love the peace of mind that the full front to back coverage and leg length gives me! I think I'll sleep in just these in summer. Lovely shade of green and easy to swap out boosters as needed, which is great if I'm on the go. Even with the booster in it doesn't feel too thick and padded, I could forget it's not my usual underwear. I find the thighs scrunch up a bit over time as I move, so I might not wear these under some thing super fitted like leggings (or maybe that would prevent it from shifting?).

13 yr old loves these

My daughter has a very heavy flow the first few days. She wears period panties from another company (didn’t know about Aisle yet) that have the maximum absorption ability. She would have to change her panties 4 times a day, which is hard to do being 13 and at school. I found the boost boxers which are a great length, as well as the reusable pads and the booster, when wearing all 3 together, she is able to go the whole school day without leaking. She says they are comfortable and not too bulky. I bought enough to get her through the first few days. They have been a game changer for her! She feels confident that she can last the day.

I will never use a normal pad again

These are so comfortable, I love them!! I have reusable pads from other companies and I’ve tried using a menstrual cup, but sometimes my body just isn’t about it - these are so easy to throw on and know I’m good to go!
