I have a couple extra bivy sacks that me and a group of friends bought but never touched. These are all brand new (never used, still have tags), highly rated, and excellent if you're the survivalist, ultra-light enthusiast. I'm trying to get rid of these ASAP, so if you're interested, shoot me a message before they're gone.
