A:AnswerNo, there is only one exterior zipper. There is no zipper on the inside pouch either. So if you want to charge while in the case, you will need to leave the case open.
A:AnswerYes, the grip is grey. I bought this for myself and I also bought one for my friend's son who is 13 and it works for both of us.
Also it's easy to put on and does not block anything.
