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 and absorbent

These boxers are a game-changer! Super absorbent and stay put without feeling bulky or irritating the skin. I have endometriosis and on my heaviest days I will leak through overnight pads in about an hour, sometimes enough to soak through multiple layers of clothing. The boxers (with a booster) survived a full 8 hour work shift with only minimal leakage. On lighter days they can be used without the booster and give me confidence to not bleed through my clothes.

Amazing

These are absolutely life-changing, these have a barrier all the way front and back, and have a wide enough crotch area that you actually feel like you're not going to leak through. My periods are incredibly incredibly heavy and I was having issues with bleeding through even with my diva cup, constantly. The only feedback I'd offer to the design team is to make sure they accommodate rounder, bigger butts, they aren't really high waist on me because the fabric has to stretch around my fairly large butt, but when I size up to an extra large, the waist is way too big. I'm more of a medium to large, but I go with a large because it does give me a little bit more of the high-waist that's pictured. But really they fit a bit lower on my hips than what's pictured here.

Comfy, absorbent, never going back

just wore these overnight (6pm to 6am) and am thoroughly impressed with how comfy and absorbent they are! I had no leaks (unheard of for me, I have a hella heavy flow), the underwear didn’t bunch up or move around, and there was no discomfort at all. I’m really glad I made an investment in these and will continue to recommend them to others (and definitely get a few more pairs for myself!).
