My approach to backpacking is to buy for comfort and then figure out how to make it smaller or lighter. I bought this tent to replace an older tent that weighed about twice as much but was smaller. I'm a big guy and I'm very comfortable in this tent. The vestibules are a good size and without the rain fly it's essentially sleeping under the stars. Very nice.
The material is very thin and I wouldn't use it without a ground cloth. I don't know yet about the durability of this item. So far, I have the impression that it will last.
It's hugemongous in the provided stuff sack. So an additional compression sack is necessary. But with a compression sack it's an acceptable size, even including the ground cloth.
