Well thought out, flexible, and super comfortable even with a heavy load.
What I like best is the good fit even with short back lengths (up to 42 cm), the adjustable lap belt, the large front opening, the stretchy mesh pockets, the sturdy aluminum frame, and the extra front carry handle. The removable lid compartment and the elastic outer pockets offer a variety of additional stowage options. If the 75-liter capacity is too tight, there are still the 5-liter side pockets for additional storage space as an accessory.
