I purchased this, on sale, about a year ago and when I received it I was pleasantly surprised with the quality of it but disappointed because the size was misrepresented enough that it wasn't going to be an adequate replacement for my current bag.
The dimensions on the Soma website have been corrected to an adequate extent since then, but my actual measurements of the bag in hand are the following:
8.5" depth seems accurate (if front and bag pockets are included), the height of the bag is 8.5" and the width is 10".
I paid $104 for it on sale. Make me a reasonable offer and pay shipping.
