Here's what other sites are saying:
Getting the right sleeping bag for a fall backpacking trip can be tricky\227a 30-degree bag doesn't provide enough insulation, while a 0-degree bag can be overkill. But the 15-degree Big Agnes Crater Down Mummy Bag is just right for your autumn adventures. Big Agnes stuffed the Crater Sleeping Bag with 600-fill goose down and engineered it to lock out drafts, so you stay toasty warm in the brisk air. The Crater does not have any insulation on the underside, but features a sleeve for your Big Agnes mummy pad (sold separately). This integrated system prevents you from rolling off your mat as you sleep and cuts down weight. It also cuts down space in you pack since you can leave the pad in the Crater's sleeve, roll them up together, and stuff the whole mess into the included sack.
