FAQ

How do BASE period underwear work?

Aisle BASE period undies feature a specially-engineered lining that combines super-absorbent Truetex™ technology with a leak-proof layer to keep you dry and feelin’ fly.

Do your period underwear contain PFAS?

No detectable levels of PFAS have been found in our underwear, based on a detectable limit of one part per million

FAQ Image

Do I need to wear a pad or tampon with them?

Our period underwear are designed to be worn on their own, but they make great backup protection for a tampon or menstrual cup too!

How do I wash my Aise BASE undies?

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! Just make sure they’re fully dry before storing or reusing.

Are BASE underwear compatible with Aisle Boosters?

We kept it super simple and streamlined with BASE undies, so you can just put 'em on and go. There are no pockets in the gusset of BASE undies so there's no need to use Aisle Boosters.

Good option

They aren't as comfortable as the boost pairs I have but are good for light days.

Comfy and secure

I pair these with my menstrual disc and wear them on their own on light flow days. They fit true to size and I feel confident that I'll have no leaks.

Fine product

They fit fine and everything I just expected more absorbency. The absorbency says 4+ tampons, but I feel like it was more so for light flow and I just don’t think it is 4+ tampons worth. I don’t even really bleed all that much and I don’t usually go through 4+ tampons in a work day on my period, but every time I’ve worn them they leak. I don’t know if it’s an absorbency issue or a design issue, as they leak right where the seams are. I’m still happy to have them for bedtime, but I don’t feel comfortable wearing them out and about during the day or at work. I don’t think they’re a bad product or anything, and I think the materials used are definitely a lot better than others on the market, but I was a little bit disappointed. I would consider ordering up when it comes to the absorbency you’re looking for.

Perfect end of period pair- let’s me feel like a normal person!

I wear these on the last day(s) of my period, when I’m tired of jamming discs/cups up there or tired of seeing my more bulky boost boxer briefs, and ready to get back to feeling normal. Or I’ve also used them as backup to cup/disc on days when I’ve got something too important going on to be able to pause for an adjustment. These are extremely comfy and not too bulky and make me feel like I’m free of my period, even when I’m not lol.
