100% cotton is not naturally waterproof. Cotton is a highly absorbent material, meaning it will soak up water and become wet. To make cotton fabric waterproof, a treatment with water-repellent chemicals or coatings is required. This can be done through various methods like waxing, laminating, or using a durable water repellent (DWR) finish. If you need waterproof attire, look for clothing that has already been treated for water resistance.
