I've thankfully only had one crash with a backpack on, but it was in gravel, so there wasn't really anything to catch and roll me. In that particular case, I had my rain pants and jacket liner inside and it likely saved me a few bruises.

The bigger problem with the one I have however, is that it is a standard two arm strap version and my shoulders are a bit on the wide side. I end up having to loosen the straps a bit to get over my shoulders with CE padding, and this leads to it being more floppy than I would like, and some eye opening moments in heavy wind or when semi's pass by and wind tries to catch and whip me off the bike.

I pondered the Kreiga R25 with the aluminum sliders, and four point quadloc harness, thinking the sliders might help in the catch and roll department, but $$$.
