However, U by Kotex® | THINX® Reusable Period Undies has multiple layers of materials in the crotch area that will provide the absorbency and leakage protection. The layers include;
- Main body (Hydrophobic 100% cotton) – hugs and fits the body
- Top layer (100% cotton) – absorbs the fluid and wicks the fluid through the absorbent core
- 2nd layer (100% polyester or 100% cotton) – this serves as absorbent layer. It holds the fluid.
