Great travel backpack used for one overseas trip. Osprey Farpoint pack 70. Larger size but we still got it passed as a carryon. Technically not carry on size so don’t count on it. Super convenient as it opens like luggage not tip loading. Easy for train travel and has the detachable day pack for city sightseeing. Has a few scuffs from use but great condition. All zippers are working and of course Osprey offers a lifetime guarantee if something happens to break
