I bought this as a travel backpack and used it for the first time on a trip to DisneyWorld and Tampa. I have the Osprey Daylite but wanted something smaller. I removed the water bladder and added refillable water bottles instead. It is the perfect size for a day pack. I was able to pack a few snacks, Disney passes, map, id, money, iPad mini, extra battery, water and the family's phones when we were on the rides. The pack felt great all day and leaves space between it and your back to allow air flow. It has just enough pockets and I love the front pouch. It works great for a hat or boarding passes but most of the time my water bottle and phone lived in that front space.
