REI offers the Osprey Porter 46-Liter Travel Backpack in several colors (Black pictured) for $130. In cart, it drops to $96.93. With free shipping, that's the lowest price we could find by $33, although we saw it for $15 less in February. It features padded laptop and tablet sleeves, multiple compartments, compression straps, padded hipbelt and sternum strap, and top and side handles.
