while hiking, i attach to my backpack shoulder strap a maxpedition ( and am not into tactical and the tag can easily be removed ) "three by five" to carry my digital camera. easy to open, always at the ready, built to last.

downside is that the attachment straps - sold separately - are difficult to remove. it likes / needs to always be in the same place.
