Menstrual bikini bottoms: combine them with what you already like

Menstrual bikini bottoms work just like any other bikini bottoms—you wear them with the tops you already own. This flexibility is their greatest strength. You don't have to buy everything together. If you have bikini tops that fit well, you can continue wearing them by simply switching to absorbent bottoms during your period.

The absorbent zone is integrated directly into the fabric of the bottoms. It provides protection out of the water for several hours. In the water, menstrual flow naturally slows down thanks to the water's counter-pressure. Protection resumes immediately after swimming. No tampons, no menstrual cups, no extra logistics to manage at the beach or poolside.

For holidays, repeated beach sessions, aquagym classes during menstruation — menstrual bikini bottoms radically simplify organization.

How it works in and out of water

Out of the water, absorbent pads absorb the flow just like period underwear. Absorbency varies by model—from light to medium flow. For heavy flow, some women use a menstrual cup in addition to absorbent pads in the water.

In water, the water pressure naturally reduces the flow rate. The absorbent zone doesn't become saturated with water during swimming—the outer hydrophobic materials repel water. As soon as you get out, the protection is immediately active.

Care instructions are the same as for other period swimsuits: rinse in cold water after each swim to remove salt water or chlorine, machine wash at 30°C, and air dry in the shade. Absolutely avoid: tumble drying, prolonged exposure to direct sunlight, fabric softeners, and conditioners, which damage the absorbent fibers.

Available cuts and how to choose

Our menstrual bikini bottoms come in several cuts to suit different body shapes and styles.

The classic cut provides standard coverage of the lower abdomen and buttocks—the most versatile option and the easiest to wear with different tops. The bikini cut is slightly higher-cut at the hips for a slimmer look from the side. The boy short cut offers more coverage of the thighs and buttocks—it's chosen by those who prefer more coverage or who participate in intense water activities.

If you're hesitating between styles, first consider how you'll use it. Beach and sunbathing: the classic cut or bikini. Competitive swimming: the shorty. Water aerobics or surfing: the shorty for support.
