at first i thought ....DAMN! this might be overkill!!.........but down here in southern Louisiana its been Freekin HOT!!! i have only been able to use it twice so far and with the heat index its been 105 to 110 degrees!! and humid.....comparable to a sauna! the bag is great! it has a 100 oz water capacity! and when its african hot like its been its well worth having. it even managed to keep the water cool on a 30 mile bike ride! the back part has a cool vent system which really makes a bit of a difference, it allows some air to flow through the hot sweaty back area. and i can never have enough compartments and pockets! this has plenty. 4 of them, with a lil stretching can be reached without removing the bag. perfect for a camera and on my New orleans rides a small gun or some mace. JUST IN CASE!
