Familiarity: I've put it through the wringer
I use this backpack daily when riding my bike to/from work. It's the perfect size for a change of clothes/shoes and a few odds and ends. It IS quite small, which is exactly what I wanted. However, if you are looking for a true daypack, you'd probably want to opt for something bigger.
For me, I love the size, colors, multiple compartments and pockets, and stays nice and tight around my torso when riding my bike. Everything I wanted and expected it to be!
