I have a similar setup for an off road bag. I am using an apple computer neoprene laptop case from the 80s when a laptop weighed 80lbs. Mine is set up with: folding military shovel, ****** strap/rope, chain, clevis, gloves, old timer folding pocket knife, a folding hunting saw with multiple blades intended for hacking up animals but versatile enough for many uses, 11 in 1 screwdriver, wiss aviation snips, toilet paper, latex gloves, an adjustable wrench, channel lock pliers, sometimes a pipe wrench, a limited socket set, bailing wire, zip ties, duct tape, super glue, band aids, a ryobi tek-4 lithium 4v led flashlight (great light, compact, stays charged for years, provides over 6 hours of continuous light) and a backup Gerber multi tool. Things I'd like to add are a small Gerber hatchet and strike anywhere matches.
