I'm not even sure they make it anymore, as I bought it over 4-1/2 years ago, at a luggage store. It has the sleeve on the outside, and a long zippered pocket on the other side. Then on the inside it has a padded compartment that easily fits my 13" MAC & iPad, could definitely fit a larger computer. There's a few more pockets as well.
When it's packed, and not necessarily 100% full but let's say at least 50% full, it stands up just fine. Though I do frequently lay it down under the seat in front of me so I can use it as a footrest (my legs are short enough they are prone to dangling uncomfortably in airplane seats).
I almost always have in it: laptop, a bag of chargers, small crossbody (tucked in after I have passed through security), scarf, and a jacket/topper, earphones. That would get me to maybe 60% full. (ETA: I can fit about that much, less the topper unless it's a thin lightweight cardigan, in the Los&Sons, and it'll be 90% full).
It is by no means fashionable. It's very simple, but functional, and just the right size for longer trips when I still want to take only a carry-on roller bag plus it.
For the shorter work trips I invested in the Los&Son's bag so that I could have a fashionable laptop bag once I arrived. It just doesn't cut it for trips over say 3 or 4 days. I finally got myself an iPad as so many of our meetings these days are "laptops down" anyway. So once I got that, I also got a Knomo iPad bag. Which fits nicely inside the B&R bag, for getting there on the airplane.
Sorry that may not be much help -- my best advice is to go to a luggage store if you have one locally.
