Your questions

We thought of everything.

And if you still can’t find an answer to your question, write to us at contact@smoon-lingerie.com

Won’t it leak during exercise?

Our waterproof membrane prevents any leaks, even under pressure. Tested on ultra-trails of over 100 km.

No odor after an intense workout?

The antibacterial fiber naturally neutralizes odors. No odor, even after several hours of exertion.

Isn’t it visible under my outfit?

Seamless construction. No visible lines under leggings or shorts, even when tight-fitting.

Does the shorts replace a menstrual product?

Yes. The absorbent underwear integrated into the shorts is enough to keep you protected throughout your entire workout. No tampon, pad, or menstrual cup needed.

How long can I wear it?

Depending on your flow, the shorts provide several hours of leak-proof, odor-free protection without a damp feeling. Up to 12 hours for a medium flow.

Can I wear absorbent underwear under my own shorts?

Absolutely. Our absorbent sports underwear is designed to be worn under any sports outfit while remaining completely invisible.

Is it suitable for heavy flows?

Yes. Our sports products are available in different absorbency levels (light to heavy). Check the product pages to choose your level.

How do I care for it?

Rinse with cold water after use, then machine wash at a maximum of 30°C with your regular laundry. Air-dry. Do not tumble dry or use oily soap.

And for swimming?

Our sports range includes period swimwear designed specifically for the pool and water activities.

What if it doesn’t suit me?

60 days to try. Satisfied or your money back in France, Belgium, Switzerland, and Luxembourg.
