How do your period undies work?

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!

Perfect

These are perfect for me ! As a fat person, it's really hard to find underwear that fit correctly, and ever harder when it's period underwear, but these fit just right. It's soo comfortable, it's not too tight at all around the belly and since the material is really thin, it feels like I'm wearing regular undies.

I have a moderate flow and I can keep them on for 6+hours during the day or night without any problem. Compared to my past period undies they dry very quickly (~24hrs). It was pretty expensive all in all bc i had to pay the international shipping + customs when it arrived here but I don't regret it at all

Such an upgrade

I had the cloth pads for years and I'm so glad I upgraded! These feel like my regular underwear, I don't feel like I'm wearing a diaper anymore, everything stays in place, and I really appreciate the high waist, it doesn't fold into my cramps when I sit. Easy to swap out boosters on heavy days or leave them out on light ones, easy to wash, these have it all!

Most comfortable underpants ever!

I wish I would have made the switch to period underwear years ago. These are seriously the most comfortable undies ever! They are soft and they stay put and don't ride up. I love that they are made from sustainable, safe materials and reduce the need to purchase expensive disposable products. They're easy to wash too. If you're curious, I 100% recommend you try them out! Thanks Aisle for making such a quality product!

Amazing

First time trying out period undies and Aisle has made me fall in love! Planning to transition fully into wearing them instead of disposable pads.

Underwear fits comfortably and coverage area of liner is great since it comes up higher in the front
