I'll chime in. For all intents and purposes think of it as a Hex 4.5 ft from center in every direction. If you use all stakes, it is a little more round. Perhaps the shape confusion is more messaging. Think of it as a tipi, with some Cimarron influences to increase space (the center panel guy out). The vent is a bit different as well and is designed to be a zip down / tension fabric covered. The advantage to this is it is quite when in big wind. Set up is basically like a Cimarron and super simple. I only use 6 stakes + plus the two guy outs most of the time. Size , it is a small footprint tent that feels large for it's size. In comparison to the BT2 , IMO , it retains all that was positive (footprint, weight, wind shedding, dual entrances) but is better suited for tall people on inflatable pads, sets up faster and simpler, and vents better. In fact, it is probably better in bad wind as well. However, don't confuse it with big shelter, it is designed to be a backpacking shelter capable of sleeping two, that fits into smaller places from the desert to above timberline and performs well.
