Osprey Porter 46, used for about 1 year. It’s so sturdy and durable it still feels new! A few light scuffs on the front but can be removed by scrubbing. Overall this is a great backpack! I used it primarily for air travel and it fit as a carry on for domestic and international flights. Comes with Osprey’s lifetime warranty. From website: About this item Zippered top pocket provides easy access to toiletries and liquids U-zip full panel zip access to main compartment StraightJacket compression with padded sidewalls secures any size load effectively Description 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.
