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.

Life changing

So comfortable, I wear them even when I’m not on my period. Another great time for these - the postpartum never ending medium to light flow. Going to try them immediately postpartum next time around - wish me luck.

My favourite period underwear

I love full-coverage underwear and boy shorts even when I’m not on my period, so I love that Aisle has this boxer brief style of period underwear. I tried one other brand of period underwear and this is my favourite. I love that it’s completely full-coverage but doesn’t feel like too much fabric, and I love that with the bonus absorbency booster you can put in, I never have to worry about leaking. My periods are fairly light so I can wear one pair all day and then put on a new pair and sleep in it for 12 hours and even when I’m on my heaviest days, I don’t need to worry about leaking. This underwear is also super comfortable which I love.

Buy them

Love these boxers!! They are super comfy, wash really well, and don't look like period underwear. I love that they are free of chemicals. They come with an extra lining for very heavy periods. I like wearing them to sleep...and my daughters do too!
