We make comfortable period products because EVERYONE deserves a comfy period.
Designed with you in mind, we talked to 250+ people with periods before the first sample was ever created. Our period undies are complex period approved, so if you struggle with PCOS, endometriosis, gender dysphoria, pelvic floor dysfunction or more, we got your back! Made from recycled materials in sizes xxs-4xl.
Our Features
-
Odor-resistant
Designed to keep you fresh with a cotton layer and bamboo blend for natural odor control
-
Leak-proof
Our 4-layer gusset is ultra thin, but designed to absorb your flow and prevent leakage
-
Absorbent
Our boxer brief holds about 25 ml of flow, which is equal to 1 menstrual cup, 3 super tampons, or 5 pads.
-
Super stretchy
Ultra stretchy waistband and fabric that adapts to your body, offering a flexible fit that moves with you
Made for your flow, built for comfort
The magic stuff is inside the boxer in the gusset. Our gusset is ultra thin, but it’s still got all the power to absorb your period. Made from a 4 layer tech:
The top layer is made of a cotton material, keeping you dry and comfy during your period.
The middle two layers are a towel-like material, absorbing your blood.
The last layer is a slick, leak-proof layer that prevents the blood from soaking through.

Say hello to your comfiest period yet
Meet Aiko, founder of monthly
Our founder was diagnosed with pelvic floor dysfunction in her early 20s and had to say bye-bye to her favorite period cup and hello to a journey of finding actually* comfortable and functional period products.
After tons of trial and error and oversharing about periods with her community, she knew we all deserved more. So she created monthly. Period care made comfy for anyone and everyone…well because… we all deserve that!
