Can't really say much about zipper bag. If you're into branded items like me, then it is nice to have the RODE logo embedded on the bag. Other than that, this isn't anything too fancy. I was expecting something like Lewitt's carry pouch but it is what it is.
Pros
Dimensions (my K2 fits nicely), Price and embedded brand name
Cons
Inside of bag we have a thin layer of foam rubber so I don't necessarily think that mic is safe when carrying. A bit more padding would be nice.
