originally made an entry sep-22-09. had tested it in my backyard. Yes the colder out it is the more condensation you'll get even as a solo user and with all vents open. imho the amount of condensation even when buttoned up tight is not an issue if you have your sleeping bag treated for or is already water resistant. yes you need to avoid rubbing up on the sides as you get up. yes the poles are a pain. I bought strong lightweight aluminum tent poles because i base camp a lot and need my trekking poles. no you don't have to get out of the tent to close the upper vent. simply open the door from the top, reach out and close the vent just enough to get the zippers under the hood. this leaves you with a smaller but functional vent opening. I do use the floor and after trying other lighter options, i can say that the headaches and the fact that when something is not attached it tends to move. with the nighthaven floor the weather and all critters stayed out. yes, stayed very dry in severe rain. i bought these removable clips and attached one on either side wall of the tent and guy them out to provide better interior clearance. I also used 2 more to attach a lightweight tarp across the high peak at the door and guy the other ends out by the grommets to create a cooking/ don't let the rain come in when you open the door vestibule. with my particular extras my tent gear weighs in at 44.00 oz. including tarp floor, stakes, tent poles, guy lines, clips & the nighthaven. I will enjoy this tent for may years and when properly guyed out it will take you through 4 seasons no proplemo. I would recommend this tent to anyone looking for a one person lightweight palace. stores all your gear as a solo hiker. enjoy the great outdoors!
