The FR-1 is well-designed pouch in a useful size, about 7x5x3. On the outside, there is PALS webbing on the front, back, and sides, making it very good for attaching to other gear. I have my FR-1 on the side of my Colossus Versipack, and I could hang another pouch off of the front, if I wanted to. The back has four rows of PALS webbing and uses the long malice clips (not included), which makes for a very secure connection. The front also has a sleeve with adjustable shock cord (to hold a flashlight, or something like that) and velcro too. The top has a handle wrapped in hypalon, with D-rings, so you could attach a shoulder strap (not included).
Unlike many Maxpedition pouches, which have various additional flaps and pockets on the outside, all of the storage on the FR-1 is inside the main compartment. The zipper runs around all four corners of the pouch, so the entire front hinges open, if you want. An excellent adjustable paracord arrangement with a cord lock enables you to configure the pouch to open as widely as you want. For example, if you want to carry the FR-1 freehand, you can set it up to open 180 degrees and lie completely flat. If you have the pouch attached to a pack, vest or other gear, you can set it up to open 90 degrees or less, giving you full access to the contents without the flap opening all the way and dropping your stuff on the ground.
The inside has a large mesh pocket on the back and a zippered pocket on the front. In front of these pockets on both sides are a variety of elastic loops to hold your stuff in place, vertical on the back and horizontal on the front. This interior is clearly designed for rapid access to first aid supplies, and this is the only part of the design with which I take issue. I would like to have seen some more traditional divided pockets on the inside, to provide a bit more flexibility. This arrangement still might work out for me, though. he jury is still out.
Overall, the FR-1 is a very useful pouch, with the usual excellent Maxpedition build quality.
