Use to have one of these bags. Found it at an army supply store. They've been around for a while. At some point a friend permanently borrowed it. Cheap but wasn't very durable (the fill didn't hold up very long). Bought a north face kilo to replace it (more expensive but much lighter for the warmth). Now I own three down bags (35 degree north face kilo, 20 degree moonstone lucid, and a 0 degree marmot couloir). Once you sleep in down you'll never go back to synthetic.
