This GP series is a solid approach to a simple design with nice extra touches. Hence the name, these pouches are made to be a good medium size to carry whatever wacky item holding needs come your way.
To give better customization, there are vertical versions made for taller items and horizontal versions to have larger zipper openings. You needs may vary, but typically many like to wear vertical pouches on the sides of their tactical vests and horizontal pouches work well on the back. The same can be said for large packs. For even more options, these versions are also available in 2" and 4" depth variants. 2" is good if you want a low profile, while 4" really adds a lot more holding capacity. Luckily the 4" ones collapse flat pretty well when nothing is inside.
For features, all have a double zipper for the main compartment access. On the interior top is a loop for a connection point while sleeve dividers are on each side. My photos make the dividers look like they hang out in the center of the pouch more than they actually do, I just did this to make them visible. The exterior sides have webbing loops for mounting options and attach points. Moving to the front, all have a single zipper pocket with a bonus loop velcro area to put on your cool guy patches or name tapes. On the back is the usual PALS webbing. The horizontal ones mount well with short Malice clips while the vertical pouches use long Malice clips.
Other than that, not a whole lot else to say. They are good stuff made in the usual heavy duty Maxpedition fashion. Check these out if you would like a general purpose pouch with more organizational features than most.
