In a quest to simplify my tarp and bivy into one item, I developed what I call the "Mini Tent". As I don't spend much time in my shelter I just needed something large enough to crawl into at night with a spot for a few pieces of gear. I wanted a shelter that was sub 1 lb, could fend off a night of rain, and protect me from insects. I used commonly available light weight silynylon. My final design does all of this and weighed 12.75 oz.
