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 work well

I have been using reusable pads for a while, and appreciate the function of these as an all in one solution. I wouldn't trust them on the heaviest day without back up (at least not yet) but for every other day there was a lot of freedom to not having to think about pads or adjust them. The booster didn't come with instructions so I had it slide in the wrong way (underneath the gusset) the first time which was more fiddly than the intended way (check the website for the how to!) but it doesn't ever stay perfectly in place and without the little seams on the slide in holes for the booster can be a little uncomfortable.

Mostly love

The fit and cut of these is great. Extremely comfortable. But there really isn’t enough space for the added absorbency booster. It just barely fits and then balls up at the back of the underwear with even light movement. So I don’t recommend wearing them together. Otherwise, they’re great!

Very comfy

I love them. They're very comfy and fit well. The extra gusset thing is useless though.

Hot tip, if you're worried about wearing period panties on a long, heavy day... wear a reusable pad in the panties, then when full you just remove it and keep going!
