Just as comfortable in overhead storage as it is in train cars, the Porter 46 is the largest carry-on compatible pack in the series. This versatile weekend getaway bag offers the simplicity of a gear-hauling duffel along with everyday organization and travel convenience. A stowaway harness provides backpack-style carry when you need it and storage when the bag is checked. A sustainable build—including recycled fabrics, bluesign®-approved materials and PFC-free DWR—doesn't compromise Osprey's commitment to quality design, construction and durability.
