Polarguard® 3D

Polarguard® 3D is a continuous filament, polyester synthetic fiber used in insulating materials, primarily sleeping bags and outerwear. It retains most of its loft and insulating properties when wet. It is non-allergenic, does not mildew and articles made with it are washable. Polarguard® 3D is a softer fiber that is similar to down in its properties, and is the type most commonly used in sleeping bags and outerwear.
