Ultrafine fiber membrane is waterproof & breathable, blocks wind and water like a hard shell, and is stretchy, soft, and quiet like a softshell when laminated between an outerwear shell or fleece fabric and inner liner fabric, offering a truly redefined comfort level to the wearer. Our ultrafine fiber membrane can be modified on essential membrane basic weight, waterproofness, and breathability, depending on the application.
