If you really wanted to save weight you could go Paradox Unaweep. I just weighed a vx21 gray 3900 with base talon at 3 lbs 2
Ounces. Add 2 ounces for a 4800 which provides zippered access and when matched with a base talon is 5800 capacity.
Camo weighs very similar. Simple,
Lightweight , weatherproof without needing a 2nd mortgage
