BACTERIOSTATIC protective mask produced with high quality technical yarns: the first one is X-STATIC® METALLIC FIBER made by permanently bonding metallic silver to the fiber surface. X-STATIC® harnesses the specific features of silver to create a powerful technology that inhibits the growth of bacteria on the fabric, eliminating odors of human origin throughout the whole life of the garment. The second one, Q-SKIN®, is a polyamide 6.6 fiber with silver ions directly inserted during the spinning process that allow to regulate bacterial proliferation with long-lasting effectiveness. A special dyeing treatment makes the mask WATER-REPELLENT and guaranteed for 10 washes. The mask is comfortable and breathable, easy to use, soft and gentle on the skin. The strap is soft and elastic, tensile strength resistant, reusable and easy to wash with a washing machine.
