Under Armour Unisex Ua Roland Backpack Backpack

It looks really good and feels really comfortable to wear even with one strap off. There's enough room to fit a lot of your stuff and it has a lot of separate compartments so that your stuff isn't all in the same area and hard to take out. The only problem you might face is the small water bottle holder. If you carry more than 500ml of water, you're probably better off with something else. Overall a great bag, I highly recommend it.
