Looking for a washable period product that’s both comfortable and reliable? Do you have a heavy or very heavy flow? Want to sleep soundly without staining your sheets? Want to run, move, and stay active all day without worrying about your period?

The menstrual shorty is an innovative alternative to disposable products (tampons and pads). This piece of period underwear is absorbent and super reliable—ideal for many women and teens.

Just as eco-friendly and cost-effective as a period panty or a period thong, discover everything you need to know about the washable, hygienic shorty—a durable, practical alternative to disposable tampons.

I. Washable menstrual protection: menstrual boyshorts

Menstrual shorts: the trendy period protection

The menstrual shorty is a washable, reusable period underwear that combines style and functionality. Featuring an integrated absorbent area, it's ideal for replacing tampons or pads. Made from organic cotton in most styles, it offers up to 12 hours of protection without sacrificing comfort.


The enveloping cut of the period shorty sets this model apart from classic panties. By covering more of the stomach and hips, it reduces the risk of leaks, especially at night. Soft elastic finishes prevent visible lines under clothing. Its organic cotton structure and leak-proof membrane make it a comfortable option for heavy or very heavy flows.

More and more women are choosing menstrual boyshorts for their convenience. With an absorbency equivalent to 3 to 5 tampons, they’re ideal for long days or peaceful nights. This choice is also eco-friendly, offering a reusable product that cuts down on period waste.

An eco-friendly and economical alternative to disposable products

Unlike traditional single-use products, period shorts are part of a sustainable approach. By avoiding tampons and pads, these undergarments significantly reduce environmental impact.


It’s also great for your wallet. A menstrual shorty costs about thirty euros on average. It pays for itself pretty quickly.


A well-cared-for menstrual shorty lasts on average 2 to 5 years. This longevity makes it a smart investment that cuts down on waste and reduces the recurring expense of disposable products.

Guaranteed comfort and security during your period

Menstrual shorts feature several functional layers. An organic cotton lining prevents irritation, an absorbent layer retains flow, and a PUL membrane stops leaks.

This structure ensures comfortable wear with no unpleasant odors.

Some models can absorb as much as 3 to 5 tampons’ worth, providing 12 hours of continuous protection.

Thanks to its waterproof membrane and full-coverage design, it’s suitable for heavy or very heavy flows (such as those caused by a copper IUD). Day or night, and for peaceful nights, the shorty is as reliable as the thickest, widest sanitary pad.

IV. How to Use and Care for Your Period Boyshorts

Tips for a successful first use

It’s clearly stated in the instructions you’ll receive: it’s important to wash your period underwear before first use to activate absorbency. Air dry your underwear thoroughly. Once dry, they’re ready to wear. Start by wearing your period shorty for 6 to 8 hours. If you’re unsure or not used to it, try this new protection at home. You’ll quickly be reassured by its comfort and absorbency.


Managing period shorts daily, even while traveling


When you’re out and about, slip your used shorty into a waterproof pouch. Plan ahead and always pack a spare, just in case.


Adjust how long you wear it based on your flow. Have a light flow? Enjoy up to 12 hours of comfort. For heavier flows, choose reinforced styles. Go for a full-coverage shorty for sports or restful nights. When in doubt, a menstrual cup can provide extra protection.

Washing and care tips for your menstrual shorty

Rinse with cold water after each use. Wash at a maximum of 30°C in the machine or by
hand. Avoid fabric softener and tumble drying to preserve the fibers. Air-drying will extend its lifespan.

To keep your period shorts for a long time, avoid hot water and harsh products. Don’t scrub stains; let them soak in cold water. Store them dry to prevent odors. With gentle care, your shorts will last 5 to 7 years. Use a mesh laundry bag to protect the seams.


Don’t forget:

Avoid hot water to protect the fibers.

Do not use fabric softener to avoid residue.

Avoid high-heat drying to maintain elasticity.

Don’t scrub vigorously to protect the absorbent layers.

Store dry to prevent unpleasant odors.
