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!

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.

Wish they weren’t period underwear…

I love these things. I actually get a little excited when I get my period now because it means I get to wear the most comfortable underwear I own. Seriously, I wish you made a version of these that fit exactly the same but were just for daily wear. They’re so comfortable and they keep me feeling pretty dry even on my heaviest days. Full disclosure I also use a menstrual disc. Could I wear them on regular days, sure. But am I going to, no. I’ll just keep saving them to wear at my most uncomfortable time of the month as a special treat!
