Ultimate Direction Fastpack series really changed gear carry in the mountains. It was the first pack to take the front carry features found in hydration vests and apply them to 15 - 40L packs. It's still hard to believe that not every fast and light pack manufacturer isn't adding pockets to the shoulder straps for a balanced carry system. These packs will allow you to run with limited bounce when you're tired of downhiking and just want to get back to your car, or load them up with all the gear you need for a 48hr+ push, they are incredibly versatile.
