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

first reusable fabric clothing garment i didn't want to tear off my body . this is something i can wear which is saying a lot cus i hate the feeling of pads and period underwear but these are basically like super comfy shorts with some thicker fabric on the crotch , i can't say that i'd want to wear them out of the house though cus the idea is too foreign to me but for lounging around the house and especially sleeping it's perfect . i got a 4x and these for me loose and perfect u like the other pair i got from the period company that said they were a 4x but fit tight and awful . these are also not hideous . they are kinda fun in their colors and the elastic band with logo,

Forget you're on your period

Like the title says - when I use these with a menstrual cup, I forget I'm on my period at all. I have a heavy flow so these don't cut it on their own for the first couple days (forget the boosters - they become dislodged way too easily). After the first few days I can take away the menstrual cup and just wear the boxers all day. They're super comfortable, and the fabric is much stronger than it feels. I've had these for a year now and there's no sign of thinning fabric or frayed stitching. Thank you aisle for making a truly amazing period boxer.

P.S. Get a size up! You'll thank yourself.

THEE best pair of period underwear

I LOVE buying from Aisle! They never fail to give out the best period products. The boxer is an awesome investment to buy. On a heavy day I can wear a pair for 9 hours and not have blood leak from them. You have no idea how much blood these bad boys can hold.

The boxer is super soft and comfy and you almost forget that you’re on your period.

I can roll around in my bed with no problems of leakage.

The price might bother some people. but if you compair how much money you spend in a year on pads/tampons vs buying a few pairs of these, you will notice a difference. Remember, you buy these once and reuse them again and again. Or spend money on disposable products that you CANT reuse again and again.

Thank you aisle for showing your products on models whose bodies are different shapes and sizes. I love seeing the human body represented as it should be with Stretch marks, curves, cellulite, scars etc. shown on many of your models. I love that you show your products on real people. Real beauty is diverse. And I had an easier time finding out what size of boxers I should get and how they would look on me.

Many, many thanks to the team. Thank you for helping make my period comfortable.

Comfortable and cute

I love the black pairs. They look just like booty shorts on and they go high up around the waist which is great for me. Have only used them one cycle but highly recommend
