Excerpt: The Lowepro Flipside 300 ($99.99) is the largest of the Flipside backpack/camera bag series at exterior dimensions of 10.2"W x 6.9"W x 17.5"D (Interior 9.1"W x 5.4"D x 15.9"D). It's available in Black, Arctic Blue/Black/Red/Black color schemes. The Flipside 300 is deceiving. I swear, this bag is bigger on the inside than the outside. It is surprisingly small looking but once you open it up the interior is spacious.
Summary: With its SlingShot line of SLR bags from a few years back, Lowepro showed the camera world a different approach to quickly getting at your gear while carrying it on your back. The side-entry shoulder bags allowed photographers to "quick draw" their equipment without taking the bag off the shoulder.
