So do a lot of traveling and backpacking, also spend a lot of time in the outdoors. Currently I just stuff the camera in my pack wrapped in a shirt or something and call it good. I cant really use a purpose built camera bag or backpack as there all not practical for what I do especially if have gear for a multi day trip (tent, sleeping bag, stove, food, water clothes, etc) you need a real pack. I have several Arcteryx and Mammut packs of various sizes depending on the trip I am taking that I use.
Those that live a similar life style how do you pack your camera?
