This is a Vera Bradley backpack which I ordered a month ago from the US, I bought three different bags, couldn't decide which I liked best and have now left it too late to return this one.  It is completely unused, still has tags attached and is the new style ReActive material, the Daytripper.  Details copied and pasted below.
Incredibly lightweight for long commutes, school days and catching your next flight, you'll love the ease and innovation built into this pack. Our favorite features include the padded laptop compartment, trolley sleeve and the drawstring and buckle closure.
