Bears Rock sleeping bag, a "nebukurom" (sleeping bag). I've only used it once, so it's practically new. The color is black, which is probably no longer sold. The current black ones have some brown in them. Also, the color is different from the first photo. The outside and inside are black, and the inside is gray.
