Why choose our menstrual shorts?

At Smoon, we advocate comfort, technicality, and freedom of movement when you have your period. And in particular that they are not a brake for women who want to move!

Playing sports while being comfortable and well protected is a real challenge during this period. Discomfort, slight leakage, unpleasant sensations, it is very difficult to find the hygienic protection that will allow you to practice your sports activities in all serenity.

With our black menstrual shorts with built-in protection, you'll be able to enjoy your favorite activities without fear of leaks, odor or wetness.

Designed with ultra-lightweight, breathable fabrics and certified Standard 100 by OEKO-TEX®, our period shorts will provide you with incredible comfort and the feeling of wearing nothing. Inside the shorts, a well absorbent menstrual panty is concealed and stays in place no matter what activity you do.

FAQ: menstrual shorts

Do period shorts work?

The very comfortable menstrual panty camouflaged under our period shorts is made of three standard 100 by OEKO-TEX® materials layered together:

  • 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 question.

Menstrual flow varies over the course of a cycle, day, or activity. Our menstrual underwear is able to absorb any amount of flow over a longer period of time than disposable sanitary protection.

What size for menstrual shorts?

Choose to wear your period shorts in your usual size. Our size guide will help you do that.

The soft, breathable, highly absorbent materials of our period panties are slightly sheathing, and may relax with the first wash. That's why we recommend you buy them in your usual size to guarantee :

  • comfort
  • maintenance
  • sustainability

The menstrual panties camouflaged under the menstrual shorts are designed so that the absorbent zone is perfectly adjusted to your morphology and protects you in all circumstances, in the front as in the back. To you freedom, serenity and optimal protection during your sports sessions!

How do you wash menstrual shorts?

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

  • Start by rinsing your menstrual underwear with cold water to remove any blood from it. Don't stop until the water is completely clear. Do not use any products at this stage, water is enough.
  • Wash your menstrual shorts as your menstrual panties, in a machine at cold or at 30 degrees maximum, with the rest of your linen. Use your usual washing powder, after having checked that it did not contain neither soap of Marseille, neither soap of Alep, nor glycerin. Indeed, these products end up clogging the absorbent zone and reduce the life of your menstrual underwear.
  • Air dry the shorts. Do not use a dryer, which would damage the fibers of the menstrual panties incorporated in the garment.

Can I swim with my period shorts?

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

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