Outdoor Research Helium Bivy Tent Lightweight Waterproof Shelter

Worked just fine in the cold desert for a week. It’s tight, probably as expected, but it’s tight! I’m 6′ 175lbs -180lbs most days. What got me was finding myself in an actual unexpected survival situation and the biv did not perform, could have been bad. Long story short, I pulled this bivy out in a hurry one afternoon at the end of a 9 day solo remote expedition. Only two days left but I’d have to make it through that evening first. Unexpected heavy snow and rain socked me in on top of a mesa and I knew I needed to set up shelter quick and prepare for this weather moving in. Popped it up under an old juniper, crawled inside and after much consideration I mananged to get a message through requesting an evacuation from a friend asap. I passed out and five hours later I was awoken to a friend and a couple inches of snow. My bivy was soaked my bag was soaked, socks and pants and everything else was soaked. I’m not entirely experienced in bivouacs but had I not had an evac that evening I still wonder what wouldve happened. Waking up to frostbite in the wee hours? Going into hypothermia in such a deep slumber and then not wake up at all? I guess keep it out of moisture and on fair weather adventures only. I did lightly use weatherproofing, obviously not enough. Not waterproof, and is slim!
