Camera nerd suggested this and I'm very impressed with it. It not only protects the body of the camera from general scuffing and dirt and sweaty hands it has a great soft tactile grip. Access to the battery and connectors is straightforward and the 'cling' to the cameras body shape is tenacious - fits like a glove.
This is my third pair of hedgehogs and use them for my daily hour of commuting walk as well as weekend long walks and holidays. Nothing compares to them for comfort, dryness and durability. Goretex keeps them dry and fresh while Vibram is the best grip for all surfaces. Best in class.
Lots of padding and space for my big laptop which was a big bonus. More for 'day out' photography than casual though. Not sure what I'd do with it on flights or trains as there are other things you'd want access to in hand luggage.
