Durable and easy-to-use, the Osprey Porter 30L Pack is the smallest option in the Sojourn travel pack family. This travel backpack features Osprey's Straightjacket compression straps and padded sidewalls to protect our packables in trains, planes, and taxis with interior mesh and liner pockets to keep everything organized. The Airscape backpack panel and tuckaway hip belt and sternum straps let us carry everything comfortably as we're walking to our hotel, hostel, or yurt.
