   On top of the membrane, eVent fabric has a face fabric made from synthetic materials like nylon or polyester. This outer layer provides durability and abrasion resistance while maintaining the fabric’s lightweight characteristics. The face fabric also contributes to the water-resistant finish of the material, helping to prevent water from penetrating the surface.
3. Coating
   The membrane may be treated with an additional water-repellent coating to enhance the fabric’s ability to shed water. This coating is typically applied to the face fabric and helps prevent the fabric from becoming saturated in heavy rain, maintaining the breathability and comfort of eVent fabric.
4. Laminated Structure
   eVent fabric is often laminated—meaning the membrane is bonded to the face fabric, creating a single, cohesive material. This laminated construction helps maintain the fabric’s integrity, making it more durable and less prone to damage during use.

How Composition Affects Performance:

• Waterproofing: The microporous membrane prevents water from penetrating, while allowing the wearer to breathe and sweat without feeling damp.
• Breathability: The Direct Venting™ technology in the membrane ensures moisture and sweat are released quickly, keeping the wearer dry even during intense physical activity.
