Excerpt: It’s a backpack. It’s a computer case. It’s an iPod dock. It’s a mobile speaker system. It’s a winner. You need one. Which color should you get? Skullcandy’s black and yellow color scheme makes the most sense from the three available models of this pack. Your pack will get filthy through constant use. I really like my red and white colored pack, but its white straps quickly picked up dirty smudges when the pack was placed underneath an airline seat.
