    My favorite shelter for backpacking and car camping This bivy has been my preferred shelter for the last 3 or 4 years and I’m outdoors quite a bit. During the summer months I’ll be backpacking in the Sierra Nevada most weekends and in the winter I can usually be found running around the desert. This has been the best shelter of any of the various tents and bivys I’ve tried. I’ve used it on rock, dirt, and snow in all sorts of conditions including extended snow and rain storms and a rather memorable 13 hour downpour two years ago.I generally pair it with a neo air sleeping pad and either a hiking quilt during the summer or a heavier mummy bag in the winter.

This bivy is very warm, and like all GoreTex products, it pretty much stops breathing when it is raining or the bivy is otherwise wet. Expect some warm nights, even without the rain. I found that in a heavy rain, the bivy stayed dry overall, but you must leave the zipper open a little for ventilation and oxygen; this resulted in a wet sleeping mat. There are no covered side vents on this bivy (a small vent is way down at the feet, which is hard to access once you’re inside), so in a heavy rain you WILL get some water inside unless you use a rain canopy with it. Why not add some flap-covered, weather-proof vent points along the sides of the bivy? The hood with the bug netting works ok, but does not stay in place. I found that it would fold half way down all the…
