Yeah it does have a zipper on the top which allows you to just slip it in, and no it's not too tight a fit. I have a macally bookstand case and it fits into it perfectly. That being said, it won't fit a bluetooth keyboard. There is however a medium sized case logic esling which should allow you to fit the keyboard into it. It's definitely a minimalistic bag, and it's perfect for my needs. Highly recommended, and especially for only 25 dollars too.
