This awesome pack has only been used on one week-long trip, however does not fit my frame. It is a size extra small and very lightweight. It has the detachable brain day pack feature and is of excellent quality. It is in perfect condition and the moldable waist belt has not yet been molded so you will be able to fit it to your waist. Please feel free to message me with questions!
