This is a great little tent and well worth the extra pound or so that it adds to a bivy. It's advertized as a 3 season tent, so it gets my 5* for that. Very easy to set up, excellent quality of material and workmanship. The benefits of the "swivel pole" though are debatable: true, it increases space around your head - but it also makes the pole more bulky to pack, increases overall weight and, worst of all, it makes the top of the tent flat: not desirable in rainy or snowy conditions. Adequate number of guy-out line attachments renders the Hubba reasonably stable in windy conditions. Fly can be set up freestanding without need of footprint (contrary to description). Fly comes down reasonably far (could be improved). Could pass for a 4 season tent without the swivel pole but a few more line attachments instead, additional loops to stake it down taut, and a solid fabric inner tent with decent ventilation instead of the simple net fabric. If windy weather is a consideration and you are comparing the Hubba to the Marmot Eos, Hubba wins hands down.
