FAQ

How do period underwear 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 undies 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.

How does the Booster work?

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 period underwear?

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.

So comfortable

These are my favourite of the pairs I got. They sit really well and the seams are sturdy and stretchy. They’re super comfortable and soft. I can’t fully speak to how much they hold as I use them alongside the menstrual cup, but they’ve done really well the times my cup has leaked in the morning

For other underwear I wear a large so I got the same for these and it worked out perfectly

Would recommend and I’ll definitely be getting more when able

Best Fit

Best fit and most comfortable out of the three options I bought (brief, bikini, and hipster). The boost is a must have for me but still not absorbent enough for super heavy flow.

Pretty good!

For my first pair of period under, these were pretty good! I only deducted a star because the waistband has crunched a bit since my belly has been on it/I sit most of the day. And the insert for extra absorbency doesn't seem to stay in place no matter how much I tuck it in.
