This is the one I have. It’s my second, with the first lasting 7 years. The first still works, but it’s a bit ratty. I always use it as a personal item but also for hiking and sightseeing. It’s very light! And it can fold down into a tiny thing, but I never do that
I love how many pockets it has. Drinks are easily accessible in the mesh side pockets. I also use the bags in the second link, so nothing is loose in my bag and color coordinated. It’s very easy to unzip and see exactly what you want. Most little things I want on the airplane, I have in the little front pockets so I don’t have to pull the bag out to get it. My book I get out as soon as I board the flight.
