FAQ: our sports menstrual panties

What is the difference between menstrual underwear and sports menstrual underwear?

A menstrual panty is generally made of cotton. When you exercise, you sweat and cotton retains moisture. In contrast, a sport menstrual panty is designed with a breathable fabric and mesh* for more elasticity and comfort. You will no longer have that moisture sensation during your workout! Additionally, its elastic band hugs your hips and provides unmatched support. Plus, it gives the panty a sporty design.

*mesh: very strong and elastic fabric made of very fine mesh. Micro-aerated textile that allows for sweat evaporation.
Should I wear a sanitary protection in addition to the sports menstrual underwear?
