I posted this in this thread of my experience with mine so I figured Id transfer it here.

Heres my posts on it.
I had it in OD green (which looks awesome and not military at all). I loved it. It was my all time favorite bag. The only issues I had were that some of the pockets being shapped triangle had wasted space and at least one was hard to get stuff out of, the strap started coming apart at the base and the shoulder strap even adjusted to the smallest size seemed a bit big and Im 6'2" 190lbs. With a coat that wasnt an issue and overall it wasnt a big deal. As for the coming apart, I used every single day to conceal carry at work and it didnt seem like it would fail, it was just coming apart. Even still Maxpedition paid for shipping to do an exchange but shitty ass FedEx "lost" the package in their drop box and would cover the bag since it was never scanned in so I never got the exchange.
Over all even with the issues, the second I have money Im buying it again. The bag was super comfy, looked great, very very quick on and off, and drawing a pistol from the hidden compartment was as quick and easy and a small of the back holster, especially if you keep the zippers positioned right.
Also as far as space, it fit my older laptop, books, and lunch. And on gym days my running shoes would take up most of the usable space but still fit in with clothes, water, some books or the laptop.
Honestly it would be a perfect E&E/get home bag.
ETA: I found the pics I originally sent to Maxpedition for the exchange
Like I said in spite of the issue, Im in full support of the bag. Usually if a bag fails then thats it for me but its just a really good design.
