FAQ: Period Shorts

Do period shorts work?

The very comfortable menstrual panties hidden under our period shorts are made of three superimposed standard 100 by OEKO-TEX® materials:

  • a draining material
  • an absorbent material
  • waterproof and breathable material

These high-performance materials are effective regardless of your menstrual flow and will allow you to practice the sport you love without asking yourself any questions.

Menstrual flows vary during the cycle, day, or activity. Our period shorts is able to absorb flow, however abundant , over a longer period of time than disposable period protection.

What size for period shorts?

Choose to wear your period shorts in your usual size. Our size guide can help you with this.

The soft and breathable materials with high absorption capacity of our period panties are slightly sheathing, and can relax after the first wash. This is why we advise you to buy them in your usual size to guarantee you:

  • comfort
  • maintenance
  • sustainability

The menstrual panties hidden under the menstrual shorts are designed so that the absorbent area is perfectly adjusted to your morphology and protects you in all circumstances, front and back. Freedom, serenity and optimal protection during your sports sessions are yours!

How do you wash period shorts?

In order to keep your black period shorts as long as possible, it is essential to follow some washing instructions:

  • Start by rinsing your menstrual lingerie with cold water , in order to evacuate the blood which is there. Stop the operation only when the water is perfectly clear. At this stage, do not use any product, water is enough.
  • Wash your menstrual shorts like your period panties, in a cold machine or at 30 degrees maximum , with the rest of your laundry. Use your usual detergent, after checking that it does not contain Marseille soap, Aleppo soap or glycerine. Indeed, these products end up clogging the absorbent area and reduce the life of your period underwear.
  • Air dry the shorts . Do not use a dryer, which would damage the fibers of the menstrual panties incorporated into the garment.

Can you swim with period shorts?

Our ultra technical materials certified standard 100 by OEKO-TEX® are not designed to go in the water. We therefore advise against using our menstruation shorts when swimming in the sea or in the pool.

To practice water sports in complete serenity and comfort, opt for our menstrual swimsuit instead. Also available quickly on delivery and at a very affordable price, it is very efficient, contains a high absorption capacity, and will offer you the optimal waterproofness you will need to practice your favorite activities in the water .
