Voting Question: Questions about mosquito netting?

These are questions about the store-bought mosquito nets (Coleman, Coglans, Stansport, etc,)

1. How the hell do you get in it? I tried looking everywhere online and can't find if theres a zipper or
what.
2. Are they "sealed"? As in, are there 6 side to them?
