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.

A bit snug but really comfy

Loved serval pairs before and wanted to try this one I’m in between sizes but went with one I normally buy in I’d say for this if your in between go with the larger. Was a bit snug but still love them

Favourite underwear!

I've always been bad a tracking my period and I spot randomly because of my birth control, these are super comfortable and make me feel so secure! They're really gender affirm, both because I finally have boxers made for a body like mine and I don't have to fuss with "feminine" hygiene products

Hassle free!

Leak proof, comfortable, long wearing, long lasting, highly absorbent, what more could you ask for. This product makes my period more manageable and has saved me hundreds of dollars in disposable period products. As a fat person, I really appreciate the gusset being an appropriate size for the sizes I’ve purchased in the past(5x, 3x, 2x). They are extremely stretchy and non restrictive. Love em!

LOVE

love them! so comfortable and easy to wash. Im 5'4, 121 lbs and I wear the size medium because I have wider hips and these work great for me. I could probably get by wearing the small as well but I think it just depends on what kind of fit you want! I ordered all the women in my family a pair
