In the past, fabrics were coated with oils and waxes in order to repel water. But these were often heavy on the fabric and needed to be constantly reapplied. Modern waterproof fabrics use a thin waterproof membrane. These can be engineered to allow some moisture, like sweat, to pass through them, resulting in a more comfortable garment. A durable water repellent treatment (DWR) is often applied to the outer face fabric to help maintain the waterproofness and breathability and to ensure the membrane works as efficiently as possible.
