This functional feature is obtained by applying a hydrophobic treatment to the fabric. This process prevents water from sticking to the fabric, causing it to "slide" off without soaking in. As a result, the garment remains lightweight, breathable and warm.
The effectiveness of the treatment can be restored during the product's lifetime. Use sprays that are applied to the outside, rather than additives used when washing the garment, which can damage the product's breathability.
