Warm backpacking trips require a lightweight, compact, and versatile sleeping bag like the Exped DreamWalker 250 Sleeping Bag. Super soft and fine 840-fill goose down insulation provides the right amount of warmth for temperatures around 45 degrees. Its rectangular shape offers a lot more versatility than the ever-popular mummy bags, like switching the bag to a blanket by unzipping it completely and stowing the hood to transform it into a blanket. And you can unzip the middle opening, slide the bag over your head, and wear it like a poncho while you hang out with your buddies around a fireplace on a cold night.
The DreamWalker 250 also features a flap pocket on the bag to store any small items you might want in the night or stuff you don't want to get cold, like your contact-lens case. It comes with a waterproof stuff sack to take on river trips, and the mesh storage sack lets the bag retain its fluff for longer lasting quality when you aren't using it. The sack also doubles as a mosquito net when you camp in buggy environments.
