Like all Kata bags, this Access-17 PL is weird. It looks like a little backpack, but it's a shoulder bag; rather than dividers, this case is designed to hold a camera body with large lens (think Lowepro's Topload Zoom series). The special-purpose front pocket holds a little foam skewer thing that Kata calls a "Spine Guard", which is not designed to guard your spine- it's meant to provide extra structure- but sort of looks like a spine, which is... interesting. Jury's out on why it's removable, except to let you relive your 90s arcade days and yell "FATALITY!" any time you're in a nostalgic mood. Interior dimensions are 10x18x28cm.
