Bottom Line If you want as light of a pack as possible but can't give up anything in the way of comfort or suspension, this is your packThis super-light pack caries loads like a pro and has just about every feature you could ever wantThis comfortable yet supportive pack has an extremely functional set of features and is one of the lightest in our testThe Features on the Flash 55 are some of the best and most versatile of all the packs in our testThis lightweight pack performs really well unless it gets overloaded with too much weight
