Although these pouches have been around for a bit, that doesn't make them any less cool. The big point that sets this dump pouch away from others is its foldup ability. This is a great feature since most of the time a dump pouch will be unfilled when on one's kit.
When needed in full form, just pull the main flap to let the pouch expand on its own and then push the flap inside the pouch to make a nice clean drop hole. For hole size adjustment there is shockcord and cordlocks on each side of the pouch which makes resizing nice and ambidextrous. I recommend sizing the opening about where you want it before folding up, but resizing later is also easy. Main configurations of the pouch include: folded up, unfolded with flap externally closed, and unfolded with flap secured to the inside velcro. This design also excels in mounting options. One can use the flap on the back to thread a belt which is wide enough to mount most MIL belts. PALS is also on the back to allow MALICE clip connections to any of your PALS equipped gear. Finally there is even a silk clip included which allows mounting to 1" webbing or something similar. This works well for quickly attaching to backpack straps. As for what you put in there, the size is great for a vast assortment of items. On the MIL side it will fit 7, 30 round NATO magazines and for the LE side it makes for a good evidence collection pouch. If you are new to dump pouches, it is recommended to generally mount them on your weak hand side. This way when your weapon is in your strong hand, the weak hand can easily get to the dump pouch.
