I used this backpack a few years ago for a long trail while staying at a hotel in Okinawa. It's multi-functional with lots of storage and was very useful. I'm still thinking about using it myself. The holders on both sides can fit 1-liter water bottles, and sunglasses can be stored on the outside. There are many other storage compartments, making it functional. There's a pocket with a shock-absorbing pad inside, which can hold a laptop. The pocket in the 10th image is surprisingly useful. I used it for things like a shell jacket and snacks. I also like the chic and calm design that's typical of Lululemon. Recommended for travel, everyday use, and minimalists. I think the capacity is 23 liters, but I apologize if I'm mistaken!
