Why use a menstrual swim brief?

Whether you’re used to wearing tampons in the water or avoiding swimming altogether during your period, both situations can be uncomfortable with a regular bikini. Tampons are not the most pleasant option — they can cause dryness, irritation, or discomfort for some women, and they generate a lot of waste.

Staying on the sidelines isn’t ideal either, especially when it’s hot and all you want is a refreshing swim.

That’s why the menstrual swim brief is the perfect solution for carefree vacations. Waterproof and protective, it looks and feels just like a classic swimsuit bottom.

Smoon designs elegant menstrual swim briefs with an invisible, minimalist protection layer, so you can feel completely comfortable at the beach — even during your period.

Thanks to its sleek design, you’ll quickly forget you’re even wearing menstrual swimwear.

Additionally, because the menstrual swim brief is reusable, it’s an eco-friendly option made from materials that are gentle on both your body and the environment.

How to care for your menstrual swim brief?

Our menstrual swim brief is waterproof, fully leak-proof, and reliable, but it still requires regular care to maintain its performance.

Be sure to clean your swimsuit after every use, whether you’ve been in the pool or the sea, to ensure maximum protection each time.

Start by rinsing it with cold water. Then, you can either hand wash it or machine wash at 30°C with a gentle detergent.

To preserve its absorbent properties, avoid using fabric softener and do not tumble dry. Simply air dry your menstrual swim brief — that’s all it takes!
