FAQs
How long can I wear Iris + Arlo period underwear?
It is essential to know your flow to determine the ideal amount of time to wear them. We recommend that you stay at home when using them for the first time so that you can see how many hours your panties remain 100% comfortable. For your information, period underwear can be worn for up to 12 hours.
Can there be odors?
It is normal for menstrual blood to have an odor; it is natural. The difference is that our panties are designed with breathable, natural fibers that limit the feeling of wetness and reduce odor concentration, even during heavy flows.
How long will my Iris + Arlo underwear last?
Our period underwear are designed to last as long as your regular panties, which is on average 5 years depending on how often you use them and how you care for them.
