Teen period panties: ideal from age 10–12
A first period without stress. Made in Portugal from certified organic cotton and guaranteed PFAS-free, our teen period panties provide up to 12 hours of discreet protection.
A teen period panty is an absorbent underwear specially designed to protect teenagers during their period. Thanks to several technical layers, it absorbs menstrual flow while staying comfortable and discreet under clothes. Period panties for teens are particularly suitable for a first period because they’re used just like regular underwear and provide reliable all-day protection.
