Layers of Defense - Omni-Tech's first layer of defense is Omni-Shield, which prevents most water from ever making contact with the inner layers. Next, a microporous membrane provides the primary impervious layer of defense by completely blocking the passage of water molecules into the fabric.
Let Moisture Escape - Omni-Tech membranes are 100% air permeable, which allows moisture vapors to escape. This superior breathability keeps you dry from the inside out. Lastly, lining materials protect the Omni-Tech membrane from underneath, while adding additional wicking properties.
