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.

So great!

These boxers are comfy and magically absorbent. Their size guide is accurate. I sized down with the intention of avoiding leaks and the size the website suggested is actually ideal, so don’t size down. Deeply grateful for the gender expansive, affirming options in menstrual management. Gratitude, Aisle!

Comfiest Period Underwear ever

This are definitely some of the best. I have tried two other brands of period underwear and these are superior. Really comfortable. The fabric is super soft. Boost's are a must for heavy days.

The best

Absolutely the best choice of all the options out there. Love the complete leak coverage and the removable pad. So well thought out. I bought five pairs total after trying the first. Great company as well. I do wish there was a higher waist option, but they're high enough. I have an incredibly heavy period, so I wear these with a diva cup part of the time as well.

4 Stars

It is comfortable. Not sure if the legs ride up. I was walking a bit and it rode up a bit. Worry if wearing long term it will ride up more. Love the boost so I can this throughout without changing underwear. Great back period coverage. Goes all the way up.
