The overall build quality is good. I like the two pockets on the belt that I use for car keys, multi tool, and cell phone. I love the holster for the mouthpiece that keeps it clean and makes it easy to both retrieve and put back. The amount of water is good enough for short to medium length rigorous exercise. It is easy to fill.
I find the "moflow" system to be a bit of a gimmick. Pros: It is easy to use the pump and add air to the reservoir which makes the water flow more strongly for drinking and also helps hold the shape of the bladder so you don't need to adjust the belt as often for a tight fit. Con: Problem is that it only works for maybe the first 33-50 percent of water usage and then there is not enough air pressure to assist with the flow of water. When there is no help from added air pressure, the mouth piece for this pack has much less flow that most hydration packs. You have to bite and suck to get a drink.
All in all I like it and use it often. I prefer hip hydration over backpack hydration when I can find a decent system and don't need more water.
