Pyramid Seven LLC is a Chicago-based company that creates boxer briefs for periods, regardless of gender. We begin from the premise that there are people who are born with a uterus who may identify anywhere along the gender spectrum. Pyramid Seven LLC seeks to validate their gender identity and expression every day of the month. Our handmade, hand-dyed boxer brief made from an organic cotton jersey fabric is the first of its kind in the period underwear market.

Our underwear allows a person to wear any available menstrual product comfortably without worrying about leakage, bagginess or discomfort. Our sizes range from extra small to extra large and are designed to fit a wide array of bodies. Our goal is not only to bring gender affirming underwear to the market but also to showcase the diversity of our community.
