I just received my new size 6Z horizontal Cache for my Macbook Pro (I have the latest version that just came out earlier this year). I guess the fit is a little looser than what I was expecting. Horizontally it is a little loose and vertically it is almost an inch taller than my laptop. If I hold it by the sides and tip it upside down it slips out with one good shake. I know I won't be holding it upside down in normal use, but I am concerned if someone such as a TSA screener grabs it and inadvertently holds it the wrong way.
Is this normal or is the Cache I received a little on the large side?
