Here’s one we’ve been itching to tell you about since we saw it at Shot. The Mystery Ranch Overload is the Clark Kent of backpacks. It looks pretty mild mannered just sitting there — but unclip a few buckles, and the frame opens up like a taco to reveal an adjustable area that is ideal for carrying heavy and awkward items such as mortar system parts or ammo cans. This arrangement makes the load more manageable because the weight of the “overloaded” equipment is carried centered and close to the back, instead of strapped to the outside/top/front of the pack.

Here’s the man himself to explain his creation. There are few photos below showing the rig hauling some Marine Corps mortar tubes and base plates. The bag alone weighs 4.5 lbs, holds about 4,200 cubes, costs about $389 and should be in stock by early April. If you already have a NICE frame (standard or BVS), your good-to-go. Otherwise you’ll need to shell out for one.
