I am looking for a thin sleeve to throw Macbook Air in my laptop backpack. Also I would like to have it fit my other 13.3' laptop. Any good choice? I don't need it to be super protective but good enough to have some basic scratch protection.
I also wanted super light and so far the most promising I found is radtech sleevz (radsleevz on amazon) - the weights are between 33-42g, that's less than 1.5oz. I'd love to hear though if you find something better/lighter.
