Underwear 101


What is Menstrual Underwear? 

We are here to solve all of your menstrual problems by adding reusable, eco-friendly, highly absorbent, and leak-proof underwear to the list. Menstrual underwear is a moderately new expansion to the feminine hygiene industry. Adding a layer of super absorbency fabric is incredibly helpful, as it protects a woman's clothes against leaks. In addition to the fact they prevent leaks and stains, but also helps to avoid roughness and annoyance that could be caused when a pad rubs against your thighs or the awkward feeling from tampons.

Our antimicrobial, odor resistant undies can be worn as a reinforcement with your tampon, menstrual cup, and eco pad, or even on their own, on lighter days. Contingent on what level of absorbency you select, they are comparable to holding a half a tampon or two depending on your flow. Hooray for double protection! All things considered; you can never have too much.

Some of our menstrual undies come with kangaroo front pockets, you can place heating pads inside to help with uterine cramping. Here at Tricorium, our mission is to offer you peace of mind against leaks that you’d never get with a pair of standard panties.
