What characteristic does a fabric have if it is described as "water-resistant"?

A fabric described as "water-resistant" is characterized by its ability to repel water. This means that it has been treated or constructed in a way that prevents water from soaking into the material, allowing it to act as a barrier against moisture.

Water-resistant fabrics are commonly used in outdoor clothing and gear, where protection from rain or splashes is necessary, yet the fabric may still allow some level of breathability to keep the wearer comfortable. This characteristic is particularly important in apparel designed for variable weather conditions, as it provides functionality without completely sealing off airflow.

The other options do not align with the definition of water-resistant. Breathability refers to the fabric's ability to allow moisture vapor to escape, while absorption suggests that the fabric would take in water, which is the opposite of water resistance. Porosity relates to the number and size of holes in a fabric, which would typically allow water to permeate rather than resist it. Therefore, the correct answer emphasizes the essential quality of the fabric to fight against water ingress.
