On a cool, early morning at Numa Creek camp on the Rockwall Trail in Canada’s Kootenay National Park, I told my wife I was heading for the camp’s cooking area to fire up our stove for breakfast. She responded in her way of letting me know she wasn’t getting up yet: “It’s cold out there.” I said, “That’s why I’m staying in my bag.” And I was: Within seconds, I converted my DreamWalker 450 bag into a long down parka and proceeded to wear it walking and sitting around in camp.

With a full-length, two-way, center zipper, zippered armholes, and a foot end that opens and seals with a drawcord, the DreamWalker morphs from bag to long down parka or blanket. To wear it as a parka, you fold the foot end up and snug the drawcord around your like a belt. It lacks sleeves, so I needed a long-sleeve base layer and often a shell jacket underneath it to keep my arms warm. Still, the DreamWalker allows you to leave a down jacket at home on many three-season trips, or bring a lighter puffy jacket than you would otherwise on colder outings—removing significant weight and bulk from your backpack. For side sleepers like me, the center zipper offers the added benefit of no zipper pull hanging in your face. The design is so simple and efficient it’s a wonder more manufacturers aren’t copying it (or more consumers aren’t demanding it).

The bag’s EN ratings of 46° F for comfort, 37° F limit, and 12° F extreme seem conservative. Stuffed with 11.6 oz. (330g) of 750-fill goose down, it proved warm enough for me (I’m a warm sleeper) wearing only a long-sleeve top or T-shirt, underwear, and socks, and for my skinny 15-year-old son on nights in the 30s and 40s Fahrenheit in Kootenay in August, and Idaho’s the City of Rocks National Reserve in June, Sawtooth Mountains in September, and White Cloud Mountains in October. On two mild nights in the 50s, backpacking the 34-mile Royal Arch Loop in the Grand Canyon, I used it opened up like a comforter.

Handwarmer pockets let me warm my fingers while doing camp chores sans gloves on chilly mornings. The armholes are convenient in surprising ways, such as allowing me to zip inside the bag and have my arms outside it to read in the tent. When the armholes, which have draft tubes over them, are closed, and the foot box drawcord is tightened, there’s no loss of warmth from them; it performs like any other bag. The 20-denier nylon shell fabric is what you’ll find on many lightweight bags. The DreamWalker 450 packs down to 8.7×9.5 inches (22x24cm), roughly the size of a load of bread, and comes with a roll-top, waterproof compression stuff sack—the rare sleeping bag stuff sack that I use. (I typically use a dry sack like the Sea to Summit eVent Compression Dry Sack; see my review of my favorite backpacking accessories.)

The design’s inherent limitations are that you can’t easily walk any real distance wearing it—as you might wearing a down jacket in deep cold—and I found the 29.5-inch (75cm) shoulder width a little snug. But for many trips, it delivers undeniable efficiency by pulling double duty. There’s also a DreamWalker 650 ($479), rated to 35° F comfort and 26° F limit.
