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!

Love the fit, hate the booster.

I LOVE the fit of these underwear. I've got a bootie and have such a hard time finding underwear that fully covers my backside and that doesn't ride up--these offer full coverage and stay in place all day, I can hardly believe it. I also feel good and sexy in these, which is always appreciated, but especially when I'm feeling physically crummy on my period. I also love the high rise waist, they feel good, hold everything in and are a real confidence booster. I wish Aisle made this cut as regular underwear in organic cotton... they would be my dream underwear and I would wear nothing else!!

Unfortunately, I absolutely hate the insert. I was intrigued by the insert when I first ordered them--but it's an interesting idea that doesn't hold up in practice. The insert does not at all stay in place and bunched up and moved around when I used it as directed with the ends tucked into the slats. It is not securely held in place and I ended up walking around with a fabric wad between my legs all day. The next time I wore these, I tried sliding the insert underneath the center fabric to help keep it in place, but it wasn't designed to be worn like this, so it's puffy and bulky. The insert does stay in place slightly better when stuffed under the underwear lining, but by the end of the day the insert started to ride back and the floppy ends of the insert were bothersome to me. I could only see this design working for people who mostly sit all day or don't move around at all while…

So comfy!

I am so happy I found these! I have tried period underwear in the past and hated how tight they felt, even when sizing up. These are so stretchy and comfortable and truly feel like a normal pair of underwear with a pad. Customer service is also fantastic, had a small hole in a new pair and they sent a replacement out right away.
