I have not owned a backpack in years. I started looking for one because I enjoy taking pictures in nature reserves and I needed a place for storage that wouldn't hinder my ability to take pictures. I have always loved Under Armour and I came across this bag when it was on sale so I purchased it and I am so glad I did. There are multiple compartments. I like the small compartment on the top, it is perfect for keys, cash etc. It's not very deep so small things can be accessed without much trouble. Also the mesh pockets on the sides are convenient to place a water bottle or other drinking equivalent into, again with easy access. Many people have commented on the durability of this bag over time but I cannot make a fair judgement about that right now because I just purchased it.
