So while the thing is incredibly comfortable in terms of back placement/shoulder weight, depending on what Im carrying, it can be a real ******* on my back. I end up with bruises on lower vertebrae from what Im carrying digging into my back. I carry textbooks, my laptop, solid notebooks, etc., so I have flat things pressing against me on a regular basis... I can arrange them when I start but inevitably theyll shift a bit.
Anyone ever padded their bag? Im thinking of getting a sheet of that memory foam and cutting it to fit in between the bag and the liner where it separates. Experiences?
