Thinx earns polarized reviews: many report it works—comfortable, leak-preventing overnight and on light-to-moderate days with stylish high-waist, boyshort, and thong options—yet significant concerns surface. Reviews cite PFAS scandals, inconsistent sizing and fit, lingering odor, limited absorbency and edge coverage for heavy flow, bulk in higher-absorbency styles, and durability issues like fraying elastics and seams.
