Extremely handy pocket for when you don't have any! Unzips to "grow" variety of ways to wear. On a belt, over your shoulder, clipped to a belt. The strap is a bit rough and can cause wear to textiles as it rubs.
A brilliant camera case that is very useful for quickly getting access to my compact bridge camera (Fujifilm X10) while walking or paramotoring. The extendible section also allows me to use it for carrying a Gopro on a monopod/gimbal stabiliser while flying and when fully extended I can quickly drop the camera into the longer pocket to stow away my camera during take off and landing. This case would be a useful container for the active person who wanted to use an action camera permanently attached to a selfie stick/short monopod. I am not sure how long the plastic attachment loops would last, but the belt loop seems good enough. A thin internal shower resistant coating without padding for impact protection but this is a good basic case.
A really useful camera case
Better attachments for long term durability?
Slips over rucksack belt, giving plenty of storage whilst on the move.
Fill it with all your nick-knacks (lip balm, small camera, pen, penknife, etc.) then, when it's full, unzip the lower zip and expand it to double the size!
It could benefit from some way to stop it sliding along the belt (I use a large safety pin) and a waterproof cover (I use a shower cap).
Provides easy access storage
