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.

So damn comfortable

Love these boxer shorts, weather them around the house as shorts, super soft and comfortable. I don't have very heavy periods so I can't speak too much to absorbancy but I've never had an issue.

Absorbent. Comfortable. Perfect.

My go to is a menstrual cup, but I experience very heavy flows that lead to constant leaks. Pads were uncomfortable and something always had to go wrong. I never had a cycle where I didn't bleed on something.

But the very first time I tried out the BOOST Boxers and I've never been so impressed in my life. Theyre comfortable and have great coverage leaving me confident that I'll never have to deal with a mess, no more running to the bathroom in emergency. Just throw these on during heavy days, or even days where there's no real need for a cup and I'm still secure and good to go.
