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.

Love these!

Big fan of these! I have period boxers /undies from other companies that don’t fit well and are REALLY thick and uncomfortable. These are thin, comfy, but still do the job! The only downside is that I wish the protective lining went up higher towards my back. Normally when I wear these I’m lying down in bed with cramps and the blood tends to travel that direction which can cause leaks.

Best period panties

I love the coverage of these. They work great on my medium days and on my heavy days they are so awesome doubled up with a pad. No leaks because the coverage goes right up to the band. Which also means great for nighttime too. I also find they don't get as humid after a long days wear like my knix do. I have the panty style ones too and they are also super comfy with the same coverage. I will be getting more of these and tossing my knix...

A LITERAL GAME CHANGER

I love these, not only was I able to travel on a 12 hour train ride without worrying but it wasn't even uncomfortable or felt wet! It allowed me to feel completely safe while in a situation where I couldn't check myself as much as I wanted to.

Not only that but I'm non-binary and the boxer fit helps me not feel dysphoric! It's so hard to find boxer period pants anywhere else. I'm so happy I decided to get these!!!
