We really like this UST Tube Tarp because it is very versatile. It can be used as a normal tube tarp, or it can be unzipped and used as a normal tarp, a ground cloth, or even a thermal blanket to wrap around you. The zipper is extremely heavy duty. One side is orange and the other is aluminized for thermal insulation or reflectivity for signaling. This tarp is ultra-light, only 24 oz., and measures, when used as a tube tent, 84" long x 40" wide at the bottom x 35" high at the peak. When unzipped as a tarp, it measures 84" long x 120" long. It includes a stuff sack, 3 adjustable guy lines, and 6 steel stakes. This is great item for bug-out bags or any emergency/survival kit!
