I ordered this after I blew out the fabric at a seam on my Timbuk2 bag. That was the latest in a series of bags which have failed in service on me; including an expensive bag by TUMI. So I bought the Maxpedition based on reviews of its durability.
The bag arrived JUST as advertised and just as pictured. This is GI-NORMOUS. The photos don't do it justice. I won't go into those details which are available at maxpedition.com or on some of the videos on youtube. It is a much larger than the 'large' standard Timbuk2 messenger bag (which in my case it replaced)

HOWEVER, I used the bag once then tossed it in my closet and haven't used it since. The reason is the size for one, but also the material it's made of, 1050 nylon. It is so stiff and abrasive its like carrying around a huge cardboard box covered in sandpaper on a shoulder strap. 1000 denier nylon as a fabric choice would have also lasted a lifetime and been much more supple and conforming to the person carrying the case.

Also, be aware, there are no internal pockets or organizational features at all, except a pocket in the lid. There is a huge center compartment, and two big empty pockets on the outside with velcro flaps. I tried various ways of carrying all my EDC, but nothing worked out. The best solution IMO is a variety of small zippered pouches throughout a bag, similar to the 511 Rush 24.<a data-hook="product-link-linked" class="a-link-normal" href="/5-11-Rush-24-Back-Pack/dp/B005AG3R8Q/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">5.11 Rush 24 Back Pack</a>

My suggested improvements are as follows:
1. Change from 1050 to 1000 nylon which might conform to the body of the wearer, and be less abrasive.
2. Put velcro under the main flap and on the outside of the two pockets so the user can just drop the flap and have it secured against wind.
3. Add a safety strap to the main strap SRB. Currently if that single buckle opens the entire bag will fall off (if on a motorcycle etc all contents could be lost.) I'm currently using a wire-tie to disallow inadvertent opening.
4. Get rid of (or redesign) the two side tube pouches. They are too long for modern LED flashlights, mace, or anything else I can imagine; yet too narrow for an umbrella.
5. Finally and most importantly, as other reviewers have noted, add another buckle to gather up the left over shoulder strap length once adjusted. Currently it just trails out like a tail and flops around. This is conveniently not shown in any 'official' photos of the bag!

In summary, a great bag which looks like it will last the rest of my life. Especially because it is so stiff I never use it.
