Sewn-in layers don't breathe. They hold moisture, take forever to dry, and create the exact environment bacteria love.
Current options are either lacy boyshorts at $40/pair or "gender-neutral" boxers that still only come in women's sizing.
You buy period underwear for 5 days a month. The rest of the time, they sit in a drawer. What if they worked at the beach too?
Breathable, organic cotton gusset with secure attachment points. Snap the pad in during your period, remove it when you don't need it. Wash separately. No PFAS chemicals.
Quick-dry, chlorine-resistant material that performs in water. Wear them to the pool, the beach, or just around the house. One garment, no limits.
Not "women's boxers" with a masculine label. Truly designed for every body. Periods, swim, everyday wear. Same garment, different use cases.
From the bedroom to the boardwalk. From your period to the pool. One pair of FlowTrunks replaces the drawer full of single-purpose underwear you never feel great about wearing.
