I bought one recently and used it on a two-week mountaineering trip to the North Cascades a few weeks ago. Although it didn't get much of a work-out because the weather was beautiful, I'm happy with its performance. I was worried because it is not fully waterproof. But I seam-sealed it meticulously and it stood up to the one night of rain we encountered on Mt. Shuksan without a single drip. I plan to use it whenever the weather is not an issue, which is most of the time I head out in the northeast. Sleeps 2 comfortably without gear and, as you know, is light as a feather.
