Probably THE most amazing modular bivy-shelter ever. Made of Mil-Spec Coated Nylon with nylon web at stress points, grommeted corners, a full-length zipper on each side(running the entire length) Alone, as shown, it's a quick set up and solid lean-to. Zip another one together, and you have a Tent, another larger shelter(tent). It comes with 2 three-section poles,6 pegs, and 2 guy lines. It also acts great as a ground cover, keeping the moisture away from where you sleep!
