Bit of a follow up on the packout backpack...
Pros:
Much bigger than expected, so holds quite a bit, including space for combi, impact and a few batteries.
Loads of compartments of various sizes, inside and out.
Sturdy base and well balanced when fully loaded (I suspect this is dependent on not loading heaviest tools up high).
Seems to be very well made, but time will tell how it holds up to general wear and tear.
Cons:
Being huge, it ain't particularly light when loaded with tools ?
Not sure this'll be of any help to the OP.
