I do not want to describe each bag individually, plus there is excellent videos on YouTube. But worth mentioning is the case for the water bottle: It is perfect to receive a Nalgene Everyday wide-mouth bottle, which can then be backed up by a clever Velcro. Since the bag can but narrow by a drawstring and the Velcro is designed to be very universal, the bag can be precisely adapted to each other smaller bottle.
The bag has a detachable waist belt, which has served me very good service in off-road driving on the quad - the pocket then sits very stable at body and dangles not constantly back and forth.
One advantage of the Maxpedition packs is that you can pick them up with a movement forward and the content then has access - which has the advantage that you do not stop or anything necessary to remove (and if you need the back, for example in vehicles free , the Pack can also easily pull forward to remove it without need).
Apart from military and outdoor applications, the Jumbo is equally well suited for trips to the civilization. Its many pockets offer almost infinite variations of usage and one is constantly more than necessary to accommodate tempted - just because the bag offers so many smart ways.
Conclusion: I love my Maxpedition bags and want to have to do without it in any case!
