Thermore introduces the new Invisiloft^® product, which offers maximum warmth per millimeter of thickness. Lower lofting than a traditional insulation, it’s a great way to enhance performance while reducing the bulk of the garment. Invisiloft^® offers the complete performance package - thinner profile, maximum warmth and exceptional hand feel in a product whose fibers are 100% recycled from post-consumer plastic bottles. Five different options available to meet all your needs.
