Not for wet weather!
I've used this tent for a total of 11 nights. It's a perfect pack size and weight, even better than I expected. Each time it has taken care of 2 adults and 1 medium sized dog very well. But...to put it up is a pain! (I have the 2007 model). One person has to crawl inside the 'envelope' while the other passes in one of the poles. It's not fun in bad weather. But my primary criticism is that it's just not dry. I spent a night in the Lost Creek Wilderness where we could actually watch the spray blow through the tent with our headlamps. Last year I spent 4 nights in the West Elk Wilderness. I don't know if it kept the rain out, but we could sit in the tent and watch the condensation roll off the inside walls...every night. It did work well a couple of nights in Grand Gulch...with no rain and a humidity of about 10%. It works great in the desert (if you can get it put up). Don't use it where it is wet!!!
