My Mongo has been good, but a couple of things bug me - the compartments aren't a great fit for glasses or regular (eg 4") multitools, the top handle sucks, and the thing won't sit upright. It's a kinda slippery unstable shape, and won't stay where you put it. I guess the design is based around body carry, and I rarely use it that way. Mostly I just carry it by the grab handle in and out of the truck etc, over one shoulder if necessary, and place it on the floor at home or wherever I am. My usage is as a well-organised EDC with an EMPTY cargo space - I like to have things like pens, notebook, multitool, flashlight, phone chargers, batteries, FAK, toiletries etc organised in the various smaller pockets, leaving the main compartment free for any unexpected or job-specific loads like documents or purchases. The 'operator' could be a contender (except that it only seems available in black these days, and I just can't do black bags!) Many of Maxp's newer designs lack exterior organisation. I have no experience with other brands though, is there something else I should check out?
