The outer shell covers the inner mesh tent. This allows for lots of ventilation, but this is not a foul weather tent because of it. I would not want to deal with wind driven rain in this thing. The floor is black nylon, a little heavier material than the outer shell. The inner mesh tent has little pouches left and right for holding small items. There is a rear vent window and of course two zippers at the entrance with a bit of overlapping nylon at the outer zipper.
Setting the tent up literally only takes 2 seconds, and taking it down doesn’t take much longer, but can be a bit tricky. I suggest you practice a few times before taking it out and getting frustrated. It claims to be a two person tent. Two people would be pretty cramped. I consider it a one person tent with plenty of room for gear; of course, I'm 6 ft, 230 lbs.
I took a couple points because it is pretty much only useful in good weather and at 30 inches wide(only 2 inches thick) may be a bit bulky for some tastes
