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.

Comfy and they work

Excellent. I can sleep in them. I've worn them with nothing over them (I wore them as both underwear and shorts) and they stayed in place during summer workouts. They looked like shorts, my friends didn't notice lol.

The boosters really help too. My waist is 32" and my hips are 41-42" and the Large is true to size.

Excellent Coverage

The best thing about these boxers is that they provide complete coverage from front to back. No leaks or other issues and they are comfortable to wear. I especially love the fact that it is all-natural fabric, no PFAS. I cannot wear synthetic material right next to my skin. That is why I love the Boost boxer.

So comfortable

Love the Boost Boxer! I bought them for sleeping in during my period and absolutely love them. Highly recommend! My hips are 35.5 inches and the XS fits perfectly.

Life changing

So comfortable, I wear them even when I’m not on my period. Another great time for these - the postpartum never ending medium to light flow. Going to try them immediately postpartum next time around - wish me luck.
