I disagree. I wouldn't want the bag to be any thicker than it already is, which would be required if you added additional padding.
I figure, if you want it protected against drops, the only way to go is a Pelican case. Otherwise, the existing design of the empeg bag is perfect because it's so small and easy to carry. Padding, structural support, and/or straps would just complicate it and make it non-useful to me.
Perhaps whoever makes an empeg bag could offer two models. The "lite" model, essentially the same as the current bag, and the "padded" model, which would be a bit larger and have padding and reinforced corners and such.
