I love these camera cases beacuase they are so beautifully designed, they protect my camera and they are really slim--no bulk! I also love that they come with a mountaineering caribiner so that I can hook it onto my strap and have my camera out in a moment's noticve without having to fumble around for it.

The Pic Pocket Camera Case (via Gary)

They have a nice fun fabric and it has interior pockets for extra memory and a carinbiner to hook on to purse or belt loop. Very functional.
