FAQ

How do your period undies work?

Our specially engineered lining combines super-absorbent Truetex™ technology with a leak-proof lining that absorb 4 tampons worth of fluid. Use the removable booster for an additional 4 tampons of absorbency.

Do Aisle period underwear contain PFAS?

No detectable levels of PFAS have been found in our underwear, based on a detectable limit of one part per million.

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!

Comfy!

I love how comfy these boxers are! They work well so far; the only downside is that the insert tends to pop out for me so I always find it bunched in the underwear. Too bad there's no underwear available with the insert sown in. I also wish the waists went up a little higher on these as they tend to roll down on me.

But I'm so appreciative of Aisle for having Plus sizes for us big girls. Periods can be extremely difficult when you are as fat as I am so I'm very grateful Aisle makes them MUCH easier for me! Thank you!

Unexpectedly good

I've had poor luck finding a brand that I can wear (as someone with extreme PCOS periods) and these boxers have actually been working for me so far!! They're also unexpectedly well-sized, so no need to order up a size.
