Great for use during exercise like running, hiking, biking, the gym and more! PATENTED ULTRA FRESH TECHNOLOGY: The microfiber interior is infused with Ultra-Fresh antimicrobial technology to control the growth of odor causing bacteria, mold, and mildew, keeping the microfiber clean and fresh - especially useful if you wear this product while working out! ORGANIZE FOR WEAR OR STORAGE: Keep cables and headphones neat, whether you are wearing them, or storing them in a drawer, pocket, car's center console or purse/handbag.
