Most pantyliners are made with plastic coversheets and synthetic fillers. Choose pantyliners that are pure, breathable cotton. Cotton naturally wicks away moisture and allows airflow to your delicate parts. Our pantyliners are 100% Natural Cotton, which means lower risk of vaginal irritation. Organic means pesticide-free. Chlorine-free means free from dioxin, a known carcinogen. Fragrance-free means no chemical perfumes. And itch-free and hypoallergenic mean less risk of irritation.
