The Bikini Period. in Microfiber For Medium Flows
purchase options
The Bikini Period. in Microfiber is a medium-flow period underwear style that earns its place in your regular rotation. Cut in a classic bikini silhouette, it absorbs up to 4 tampons worth of flow with none of the bulk you might expect. The outer layer is brushed microfiber, soft enough that you genuinely might forget you have it on, and the gusset is organic cotton for breathable, skin-friendly contact where it counts.
- Bikini cut sits low and smooth, making it an easy layer under leggings or fitted clothing without visible lines.
- Absorbs up to 4 tampons worth of flow, reliable coverage for medium days without needing backup.
- Brushed microfiber outer with an organic cotton gusset keeps things soft, breathable, and comfortable across a full day of wear.
Medium days deserve underwear that handles them without fuss. Once you find the right fit, period underwear tends to replace single-use products quietly and completely. Available in Black across sizes XS through XL, this pair is also HSA and FSA card eligible.
