safe? these things are sturdy and cheap. A good lens cover helps, but then most any old bag would work. I've used stuff sacks from REI for cameras, lenses and such, and threw thing in a regular backpack along with my other on board stuff.

It helps of course if you don't put it against something that might do damage, like a heavy book, but with kindle and various pads, those days are gone. So how much damage would a sweater, jacket, a few mags, maybe another stuff sack of meds do to a camera, unless you start using your bag as a basketball etc.?

This gear is not delicate. Sure it can be damaged if you drop it, but your biggest risks are IMHO damaging the LCD screen. Once I dropped a SLR many years ago and the lens broke off. Turns out 4 screws holding the mounting ring sheared. easily replaced and the gear worked for years more.

So my advice is that unless the camera is some kind of jewelry to you, don't worry about it. Most scratches and even dents are cosmetic. And they make you look like a serious photog who uses your gear hard.
