“Can be stuffed into a smaller bag”

“I bought this sleeping bag for my teen daughter for camping and backpacking. The cover bag it came in was huge, and since the sleeping bag expands given the space, it was very bulky. My daughter was able to stuff the sleeping bag into a smaller stuff bag and it fit. I modified the cover bag that came with the sleeping bag--basically remaking it to a smaller diameter but I kept the length. The sleeping bag fits into the remade bag and takes up no more space than our other backpacking sleeping bags, it weighs maybe a bit more and is warmer.”
