>>1274147I got the single-door variant that has a regular (storm?) door and a bug netting door behind it. When you keep that front open and open up the side flaps, it gets a good amount of airflow (there's also a small bit of mesh at the top of the back wall) and kept me cool enough during the day and plenty dry during a 14-hour rain storm. The only real disadvantages it has are dealing with guylines and the fact that it weighs like 6 pounds. All in all, not bad for $30.
And my dogs don't seem to mind pipe tobacco smoke.
