[ I am loving this bag from Hurley! My favirote part about this bag is that the zippers are very easy to zip opened and closed. You can really tell that they are made with good quality material. It fits nicely around my shoulders and feels great. I like that it has a lot of different pockets. It also has a pocket for holding my water bottle. I like the style of the bag and that it has lots of storage area in it. It's very stylish and I am very happy with it.
