I purchased this bag for backpacking into the Grand Canyon from the South Rim in late September. The first night I slept in the back of my pick-up under the stars and temperatures dipped into the 30s and I was snug and warm. The next day I hiked 5000' down into the Canyon and the temperature stayed around fifty, so I unzipped the expansion feature of the bag and adjust the main zipper to create a roomy and perfectly controlled climate. The bags light weight was an added blessing for hiking out of the Canyon where weight was a primary concern. I like the larger storage sack that came with bag so it does not damage the fill when it lies in the closet waiting for the next trip. This is a great bag at a good price.
