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 and absorbent

I was worried that the waistband would be tight but it’s super comfortable. I have IBS so my stomach can bloat really badly. Also love the absorbancy and it’s easy to wash! I have 3 pairs and I want one or two more.

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.

These are so comfortable and the material is really soft. I wear these for my heavy flow and they last pretty long (granted I work from home so I have more flexibility when it comes to to changing the pair). Highly recommend for overnight and 6- 8 hours of heavy flow!
