If you like to rock your tunes while you're mountain biking, hiking, or boarding, and can't stop to answer your cell phone or grab some hydration, then you'll love Skullcandy's new Link HydroPack which has controls for both your phone and iPod/MP3 player and a convenient water bladder. The controls of the right strap make it easy to control the music; the built-in speakers aren't bad for their size, and the set-up takes only minutes. My only quibble is that even though 6 connectors are included, they still didn't fit a Samsung cell, iPhone or Blackberry Pearl.
