Your thread (thank you for the effort) has got me interested in maybe going for parapack, but I am quite worried about the abrasion resistance vs ballistic having never experienced either of those materials.
I see you already seem to have markings on the front of it perhaps, looks like white spotting in the mid-left of the pic you have there.
What's your experience with marks and scuffs with parapack vs ballistic? Do you find you really have to baby the bags or else they'll look quite scruffy in a couple of years time?
