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.

Comfortable!

These are super comfortable and gender affirming boxers!

One star less because they did overflow the first time I used them, but not in a way that damaged any of my clothing. I recommend these for sleeping in as well.

Almost perfect

Fits well and is very comfortable. Absorbent and easy to clean. I love that it can be dried in dryer. After a few washes I noticed the elastic at the top has folded over on itself and looks stretched. Not sure if this means I got a size too small (although they fit really well and don’t dig in or anything) or if maybe they are not 100% dryer safe. They still fit well, just a visual thing that bums me out.

These were great! The insert fit nicely and flat into the gusset pouch, and I liked that there was protection running almost all the way up the back.
