I'm still trying to figure out why one would need a workout case and armband for an MP3 player that already has a built-in clip, but whatever. I suppose DLO's Action Jacket for iPod Shuffle does provide some protection from that corrosive bodily fluid known as your sweat, so that's a plus. The silvery-white color of the case accents the colored Shuffles quite nicely. The case, which will set you back about $20, is made of a polyurethane-coated neoprene to protect your player from falls and spills (the dirty, wet kind). And I have to add that I appreciate an armband that purports to fit "any arm size from toothpick to python." Plus, a clear window over the iPod's controls gives you access while still protecting the player.
