It's just a cylinder, drawstrings on each end, zipper down one seam to get in and out (just for convenience). It was a good project, simple to make, and works very well at keeping the bugs at bay.
That looks quite useful, bugnet in the summer, hammock sock in the winter, only carry what you need and a lot easier than sewing a half-mile of zippers.
