The quality is very respectable for the price; but beware: the internal mesh pockets are fragile. The lap belt is removable, which I find very convenient; by against the site dedicated to the water pouch is tight and is only appropriate for a 2L bag filled with 1.5L of water max. The volume of the bag matches the range of 36L and comfort is very correct, provided of course load properly: it is not designed to transport 36 kg! The MOLLE system will hang removable side pockets or store a sleeping bag at the bottom but do not plan to use the passersby from the front to store heavy items are: the load is too far back for whether the transport is comfortable. In summary I am delighted with my purchase: it is a tactical backpack of a very good quality / price that is sure to organize a GHB (Get Home Bag) muscular, a BOB (Bug Out Bag) light or bag touring a few days in partial autonomy (night and holiday meal). PS: the Proteus MAXPEDITION lodges in the main pocket easily.
