I have been using these underwear for years! They are super comfortable, seamless and have saved me (and my clothes) several times! Totally recommend! I am size 10-12 and the Large fit perfectly.

Aguantan bastante bien, aunque para un flujo más abundante o los primeros días, recomendaría otros de mayor área de cobertura.

These are a great product! I’ve been using them for months now and haven’t had any leaks or accidents. The material is really comfortable and doesn’t feel bulky like other period underwear I’ve tried, yet I still feel well protected.

Very happy with the fit and material. As advertised it is for light incontinence and so I still wear a light pad with it

Very high rise, but otherwise a perfect fit. Feels so comfortable even when bloated. Perfect for under work pants.
