This Mira is loaded with features: women specific fit, adjustable torso design allowing about 4 inches of adjustment to fit a 14-19 inch torso, 32L capacity with multiple compartments and large access front panel, reservoir with dedicated hydration compartment, dual hip belt pockets, integrated rain cover and two toned denier nylon for durability. Of course it has the Osprey suspended back panel, my favorite for comfort and ventilation. Received this as a gift but it's larger than what I need.
