AS COMFORTABLE AS YOUR REGULAR UNDERWEAR & NO PFAs: Our reusable underwear is functional & so silky soft! Featuring rayon, an extremely soft & breathable fabric, our 4-layer design is effective yet thin enough that you won’t feel like you’re wearing bulky underwear. The full coverage design, with optimal elasticity, is ideal for period, maternity, post-partum, bladder leakage, or sweat protection.
