The So’Stella Sport Period Underwear


The So’Stella sport period underwear is the comfortable, sustainable alternative to disposable menstrual products during workouts and training.

With its triple-layer absorbent and breathable design, it provides up to 8 hours of reliable leak protection, suitable for every level of physical activity.
The outer layer is made from a technical anti-sweat fabric that wicks away moisture and keeps your skin breathing—even during the most intense sessions.

How does the So’Stella sport period underwear work?

The absorbent core:

First layer: A breathable honeycomb zone that lets fluid pass while keeping you dry.

Second layer: An absorbent bamboo-fiber layer that locks in menstrual flow and neutralizes odors.

Third layer: A waterproof barrier that prevents any leaks.

Freedom of movement & performance:
The stretchy, flexible fabrics ensure total freedom of movement for any sport while maintaining a dry, fresh feel.
A secure elastic waistband keeps the underwear perfectly in place.

Mesh inserts enhance breathability and allow perspiration to evaporate quickly—goodbye to damp sensations.

Mesh: A strong, elastic, micro-ventilated fabric with fine netting that promotes airflow and sweat evaporation.

FAQ: our sports period panties

What is the difference between period panties and period sports panties?

Menstrual panties are usually made of cotton. When you exercise, you sweat, and cotton retains moisture. Menstrual sports panties, on the other hand, are designed with breathable fabric and mesh* for greater elasticity and comfort. So you won't have that damp feeling during your workout! What's more, the elasticated waistband hugs your hips and provides secure support. It also gives the knickers a sporty look. *Mesh: a very strong, elastic fabric with a very fine weave. A micro-ventilated fabric that wicks away perspiration.

Do I need to wear sanitary protection in addition to sports period panties?

No way! So’Stella period panties are designed to protect you in a healthy and economical way, so you can keep up with your workout routine during your period. They are guaranteed leak-proof for up to 8 hours, which is equivalent to 2 tampons. Disposable protection is a thing of the past!
Which period underwear should you choose based on your flow?

The No. 8 sports period panties and No. 12 period boxers are designed to absorb up to 3 tampons, perfect for light to moderate flow. The No. 2 thong is for light flow, equivalent to 1 to 2 tampons. The entire sports range is suitable for all your sporting activities; your choice will depend on your habits and your flow!
Can sports period panties move around and cause leaks during my workout?

Actually, no! That's the difference between these and traditional period panties.

Sorio sports period panties feature an elastic waistband and slim, fitted seams at the crotch. This design ensures that your sports period underwear stays in place, even when you're on the move!

How should I care for my sports period underwear?

It's very simple: they are machine washable! Same principle as our period swimwear. First, rinse it before the first use to activate the absorbent technology.

After use:
1 - Rinse with cold water until the water runs clear.
2 - Hand wash or machine wash at 30°C, without fabric softener.
3 - Air dry, no tumble dryer!

And that's it! Your sports period panties are ready for another workout.
