Osprey’s Quasar can carry the essentials for a full day outdoors or all the textbooks for an upper level Astronomy class. The mesh shoulder harness and backpanel provide comfort, even when the pack is fully loaded with gear, books, or heavy electronics. A removable webbing hipbelt adds extra stability under load and vanishes when you’re traveling light. Inside the panel-access main compartment, you’ll find laptop and tablet sleeves to protect your devices. Storage options include side and front stretch mesh pockets, and a zippered front panel pocket. There’s also an upper slash pocket to corral small items. A front panel bungee cord adds compression and extra storage options. If your adventures keep you out past dark, clip a blinker light to the pack’s rear attachment point for extra nocturnal visibility.
