I got one for my macbook. Its great, honestly I was going to get the shinza zeroshock, because as a student i carry a backpack around already and really wanted a sleeve. But Im really gla I got the vyper instead, it seems much more solid than the zeroshock, it has a semi hard outershell, adds very little bulk to the notebook, and has some solid inner padding. Id say go for you wont find a better one. but make sure that you want a sleeve first, cause you really dont want to buy a sleeve and then figure out that you really want a briefcase thing.
