How Waterproof Breathable Fabrics Work - Science Explained #3407655 (License: Personal Use)

The image depicts a cross-section of a technical fabric membrane where external liquid water (shown as blue droplets) is repelled by the outer hydrophobic layer, while internal moisture vapor (represented by orange arrows and white bubbles) passes through microscopic pores or channels. The layered structure includes an outer protective shell, the functional membrane core, and an inner lining-common in high-performance outdoor apparel and footwear.
