I purchased this tent for camping and backpacking. I'm very happy with this product! It's light and very simple to set up. This is a very well thought out design as far as tent assembly goes. It's a three-man tent, but I use it for me and my girl. It would be a little cramped for three people.
It's a freestanding tent, so it doesn't need to be staked down. I do recommend at least staking down the rainfly at a minimum. It helps with ventilation and eliminates condensation inside the tent.
Sierra Designs also manufactures a tent "attic" that fits this tent. It's very handy for stashing small gear items you want to keep out of the way.
