The modern man’s pockets are more crowded that an Apple product launch.  The Timbuk2 2Way is a great way to free up some real estate in your bulging pant sacks.  It attaches via a Velcro band to the strap of your shoulder bag or backpack and can hold most modern smartphones close enough to your chest that you can still feel it vibrate when you have a call.  It even has an extra pocket which can hold emergency cash or an ID. The Ballistic fabric construction gives it the look of something that Jack Bauer would use to hold one of his implements of freedom, but in black, it is reasonably understated as well.
