How to carry OM-D E-M5 to be accessible when backpacking?

I use a fanny pack type bag strapped around my waist, then rotated so the pack is in front.

The back pack waist belt fastens beneath the fanny pack and helps hold it upwards.

The fanny pack is accessible at any time without removing the back pack.

The limitation I see with the Olympus OMD for back packing is battery life.

Are you going to take a solar charger?
