It also holds up very well.

sounds like we have a similar system, Till. I use a plain document holder which has a built-in handle and is very light and then I put my computer in a bubble-wrap envelope inside the document holder. The overall arrangement is VERY light, very cheap, very durable, very computer-protective (including completely waterproof), takes up less space (depth) than any computer sleeve I have seen and is easily removed for screening.
