Waterproof on the outside - Breathable on the inside.
While other waterproof fabrics transmit water vapor (perspiration) through thousands of microscopic holes, "breathable" Hytrel has no holes. It passes water vapor with amazing efficiency by absorbing it into material, diffusing it across the membrane and evaporating it on the otherside. Hytrel provides exceptional dryness and comfort. And because there are no holes to clog, it offers longer - lasting performance.
