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!

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.

Better than Knix

These boost briefs renewed my belief in period underwear. The only other brand I’ve tried is Knix, which had a gusset that was way too short and narrow that caused leaks every time I wore them. The gussets on these underwear are actually full coverage, which means they catch everything and don’t leak. Also, these underwear can hold some serious blood. For some reason, I doubted the absorbency when compared to a typical pad, but I was very wrong. As someone who usually changes her pad 5-6 times a day on the heavy days, I only needed one set of Aisle briefs with a booster in to easily last me the entire day on my heaviest flow. These underwear also get bonus points for being extremely soft and comfortable. I could not recommend these underwear more to anyone who menstruates. They are far worth the investment.
