The door design is not awesome by any means but not a deal breaker, one spot I set up near a tree and tied the rain fly off high so it gave a little extra space going in and out.I liked the idea of these but thought the doors design for entry/exit would be annoying. How do you like that?
I did notice I would get some dirt and sand on the zipper if I wasn't carefull and it made the zipper hang up a little but not terrible.
With the window, door and roof design ventilation is not an issue!
