Do not buy this bag if you intend on carrying more than a windbreaker or sweater in it. It is a great looking bag with lots of space in its three zippered compartments and water bottle holder. Its microfiber shell is very soft and folds down to practically nothing. But the seams which attach the nylon straps to the microfiber bag are poorly made and will come undone if you have even as little as five pounds in the bag.
I bought two of these bags from the RS store in Edmonds and brought one with me to Europe on its inaugural use. It contained a tablet, a pocket RS guidebook, a printout of my itinerary, and my one quart bag of toiletries. It only made it to the airport lounge of my departure airport before the first seam broke. One side of the loop at the top came undone as I held it by the loop to set it on the floor. I reattached it using a small safety pin. A few days later in our first destination city, the other seam on the top loop gave way when being held by the loop. Okay, stop holding it by the loop. I put it on my back and walked from the train station to my hotel, about four blocks. I didn't even make it that far before the seam on the shoulder strap came undone where the bottom of the strap connects it to the bottom of the bag. it is now completely useless as a backpack.
I found a store near my hotel that sells student backpacks which are not as soft and do not fold down as small as the RS Civita backpack, but has held up to the five pounds of stuff it needs to carry.
