Multi-layer passive water barrier system

摘要

A garment comprises a body fabric having a durable water-repellent finish that substantially resists water entry pressure. At least one vent is provided in an opening in the body fabric. The vent comprises an exterior layer, an interior layer, and a spacer layer positioned between the interior layer and the exterior layer. The exterior layer and the interior layer include a durable water repellent finish that does not substantially resist water entry pressure. The spacer includes a plurality of air passages and separates the interior layer and the exterior layer such that the interior layer does not contact the exterior layer within the vent.
