I am a newer GP owner in all leather - Negonda. I love, love, love the bag ... BUT I will say that it gets VERY heavy when not even "full." I have a purse organizer from Divide and Conquer that is pretty light but this bag strains my arms at times and I don't think I carry an excessive amount.
I still love it and want it it multiple colors but I am considering the canvas version as a "lighter" option for some uses.
Thanks for this info...am considering a GP and am leaning towards canvas for this very reason. Going to try to see if I can find a shoulder version, I'm assuming the canvas is much lighter to carry than the all leather.
