Wayne Harveywrote a review of Mountainsmith Cyber II Compact Camera Case on March 4, 2010
Only the XS and the Small have the vertical shoulder srap mount for a backpack. All the rest are hip belt-attachment ONLY.
I use the size small with a Canon SD880 and mount it on my shoulder straps of my day pack. Mounts securly, does not wobble around. great little camera case.
