This pack is super comfortable and well designed. Osprey are known for high quality packs that last. This pack has a ventilated back panel which keeps the sweat away, and plenty of easily accessed compartments. There are some superficial scuff marks on the exterior (to be expected with a used pack), but no functional issues.
