Co-developed by German sportswear outfit Adidas and Griffin Technology, the miCoach Sport Armband for the iPhone ($30) is a nylon, armband with a touch-through screen cover, a pocket for keys or other small items, and an adjustable band. A Velcro closure provides a little flexibility in the tightness of the band around the arm, while a flap on the top keeps water from leaking into the headphone port cutout.
