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.

Performs well but fit could be better

I want to say that ultimately I love these and they perform exceptionally well on heavy flow days. However, as a plus size person, I don’t think they did enough fit testing with plus size models. These sit much lower on my waist than expected and are several inches too big in the waist while they fit in the hip and thigh. They are still quite comfortable and I would still purchase again, but I do think that the plus size fit could be improved, and if you have a large discrepancy between the size of your waist and hips I would beware that these won’t fit as pictured on you.

Very comfortable

I bought these to wear overnight and they do a great job. They don't feel wet and they don't leak out the top, which is a problem I've had while sleeping in other products I've tried. My only complaint is that the waistband folds, instead of staying up.
