Black Gym Sports Armband Pouch Cover Case for Apple iPod Nano 5th Generation 5G
Not designed for any exercise using biceps (e.g., chin-ups, bicep curls, push-ups).  The lack of elasticity resulted in the D-Ring ripping the strap the second time used (worn on bicep during chin-ups).<br /><br />Additionally, the orientation of the case itself seems upside-down to me.  As designed, the display has to be read upside down during normal use and the ear-buds plug kept poking my forearm when elbow was bent.<br /><br />I'm now shopping for an armband case that will stretch when needed.
