Despite the "9-person" designation, this Core tent—which has a stated floor area of just 14 feet by 7 feet—won't reasonably fit that many people. The Core weighs in at 30 pounds, limiting its use to car camping. The poles are all attached to a central hub and, with another person stabilizing it, setup should only take a couple of minutes. After watching a reviewer's video of his setup, it looks like the fly will be the fussier piece to set up since the tent is so tall. If you’re camping somewhere that rain is not very likely, you could leave the fly off. Considering how much of the roof is mesh, as well as the multiple large windows and the large interior size, there isn’t going to be much heat retention even with the fly, limiting this tent to warm weather use only.
Another excellent feature of this tent is the second door. In addition to the standard D-shaped door, one entire side can be unzipped as a second opening. This allows for great airflow, makes the tent easier to move gear in and out of, and gives you a second entrance to not disturb everyone in the tent if you're sleeping on one side. There are two mesh pouches attached to the wall to hold items securely and off the ground, another nice feature.
Unfortunately, several reviewers commented on difficulty with Core customer service so if there is an issue with the tent, getting another piece or a repair might be challenging. Our advice is to get the tent and set it up safely in your backyard so you can check it for any issues while still within the return period, just in case.
