Summary: Dust, dirt and water will get into your camera! Use a case. This one is exactly right size for the Canon ELPH. And still small enough to carry easily. Not bomb proof - but not planning on a combat zone. The outter pocket was a requirement and works as planned. Holds the extra battery and the Sunpak SC card-to-USB stick so I can down load to any computer anywhere. Zipper for outter pocket will conceal itself and is very secure, non snagging. All in one small package.
