Zipping single sleeping bags together is notoriously drafty. Instead, upgrade to a double sleeping bag for a spacious backcountry bed that’s built for campsite canoodling.

Of course, double sleeping bags aren’t just for couples. When you’re camping with toddlers who are used to sneaking into your bed at night, a double sleeping bag is a fun way to let the whole family snuggle together while you tell a bedtime story.

And if you think double sleeping bags aren’t for backpackers, think again. Many double sleeping bags are too heavy and bulky to strap to your backpack, but there are a handful of premium options with down insulation that are well-built for backpacking.

To help you find the perfect setup for your next outdoor adventure, we’ve narrowed the field to 13 of the best double sleeping bags. Whether you’re backpacking, car camping or snoozing in an RV, you’ll find the ideal bag to match your needs and budget.

Best Double Sleeping Bags for Backpacking

1. Big Agnes King Solomon 15˚

Big Agnes King Solomon 15˚

Tech Specs:

  • Temperature rating: 15˚
  • Insulation: 650 fp DownTek™
  • Weight: 4 lbs 5 oz
  • Size: fits up to 6’
  • Pack size: 10” x 21”

It’s fitting Big Agnes chose this particular name, because the King Solomon 15˚ is the king of three-season double sleeping bags. There’s no need to trade comfort and warmth for weight and compressibility — the King Solomon 15 delivers all four.

The King Solomon 15˚ uses water-repellant 650 fp DownTek™, employing Big Agnes’ proprietary Insotect Flow™ baffles to keep the insulation in place and promote heat conduction along your body. When the evening temperatures drop, the internal hood drawcord ensures a cozy, secure fit to lock in the heat. The sleeping bag keeps the cold air at bay with a no-draft zipper, no-draft wedge, no-draft collar, and no-draft center flap.

The Flex Pad Sleeve on the bottom of the King Solomon 15˚ accommodates multiple pad widths, so it’s quick and easy to connect two pads or stretch around a double pad. There are two pillow barns to keep your pillow in place through the night, and a Free Range Footbox to keep your feet from getting cramped.

Forgive the pun, but comfort is king with this double sleeping bag. The soft polyester shell fabric and the cozy polyester taffeta lining drape around your body like a comforter, so you’ll feel like you’re in your own bed back home.

The double zippers allow either sleeper to kick a leg out or ventilate when necessary without impacting the other person, and you can completely detach the top to function as a standalone camp quilt.

2. Sierra Designs Backcountry Bed 20 Duo

Sierra Designs Backcountry Bed 20 Duo

Tech Specs:

  • Temperature rating: 20˚
  • Insulation: 65-fill-power DriDown
  • Weight: 4 lb 10 oz
  • Pack size: 11” x 9”

The Backcountry Bed 20 Duo is oversized, but you wouldn’t know it by the bag’s compact packed size or sub-five-pound weight. That extra space comes in handy throughout the night and morning, and the bag’s unique zipper-less design makes it easy to find the perfect snuggle spot.

Where some mummy-style bags are constricting, the Backcountry Bed 20 Duo’s profile is boxy without being shapeless, and a cinch-closure feature allows couples to get the perfect snugness on each side. Self-sealing foot zents on each side allow for customized air flow, and the “integrated comforter” with arm sleeves mimics what you’d do at home: wrap yourself up nice and tight and get those zzz’s.

“It weighs about the same as two conventional down mummy bags and works well with two single backpacking inflatable pads,” said user Eric M. “Its like having a queen size bed in the backcountry so what’s not to love?”

3. Exped Megasleep Duo 25

Exped MegaSleep Duo 25

Tech Specs:

  • Temperature rating: 25˚
  • Insulation: microfiber
  • Weight: 4 lbs
  • Size: fits up to 6’4”
  • Pack size: 12” x 22” x 28”

The best way to save money on a sleeping bag is going with synthetic insulation, and the Exped Megasleep Duo 25 is the ideal choice for consumers who go that route. It’s perfect for car campers who don’t mind a heavier bag with a larger stuff sack.

The best part about the 4-in-1 Megasleep Duo 25 is its versatility. When it’s cold, position the dark blue side facing up to stay warm down to 25℉. When it’s warm, flip it over so that the light blue side is up and you’ll stay warm down to 40℉. Should you ever need to sleep solo, the dark blue and light blue sides both function individually as solo sleeping bags, retaining their respective temperature ratings.

The Megasleep Duo 25 uses quick-drying microfiber insulation that’s engineered to maintain maximum loft. There’s also a full-length draft tube and central snaps at the head to lock in the heat.

4. Big Agnes Sentinel 30˚

Big Agnes Sentinel 30 double sleeping bag

Tech Specs:

  • Temperature rating: 30˚
  • Insulation: 650 fp DownTek™
  • Weight: 3 lbs 8 oz
  • Size: fits up to 6’
  • Pack size: 9” x 20”

The Big Agnes Sentinel 30˚ takes home the prize for the best one-season sleeping bag on the market. It carries a steep premium over synthetic summer sleeping bags, but you get what you pay for with a significantly lower weight, greater compressibility, and superior heat retention.

The Sentinel 30˚ uses 650 fp DownTek™, a treated down insulation that repels water while maintaining insulating properties to keep you warm. There are a number of secondary features to lock in the heat, including a no-draft collar, no-draft center flap, no-draft zipper, and no-draft wedge. The hood is easy to control single handed with the low-profile cord lock, delivering a secure, cozy fit when cinched tight.

Thanks to the Flex Pad Sleeve on bottom, stretching around a double-wide pad or connecting two pads is quick and easy. There’s a pillow barn up top to keep your pillow in place through the night, and a free range footbox on bottom to ensure there’s plenty of wiggle room for your toes.

Whether you zip yourself up tight for maximum warmth or use it as an open comforter on warmer nights, the Sentinel 30˚ is an excellent choice for summer backpacking adventures.

5. Marmot Yolla Bolly 30° Doublewide Sleeping Bag

Marmot Yolla Bolly 30° Doublewide Sleeping Bag

Tech Specs:

  • Temperature rating: 30˚
  • Insulation: 650-fill-power duck down
  • Weight: 3 lbs 15 oz

The best double sleeping bags are often the most simple in design. Case in point: the Yolla Bolly 30°, an uber-lightweight bag with simple-but-effective lines that keeps its duck down insulation in place while providing a spacious interior for two.

The backside of the Yolla Bolly 30° offers a grippy surface that stays on sleeping pads better than most bags, and if you’ve slid off a pad onto the cold ground in the middle of the night, you’ll appreciate this detail. The wrap-around zipper and curved hood make it easy to find just enough ventilation and air while staying warm and cozy in three seasons.

6. Feathered Friends Penguin YF Sleeping Bag

Feathered Friends Penguin YF Sleeping Bag

Tech Specs:

  • Temperature rating: 10˚ to 40˚
  • Insulation: 900+ goose down
  • Weight: 2 to 3 lbs.

Don’t sleep on Feathered Friends, a boutique sleeping bag company out of Seattle, where they’ve made sleeping bags and goods since the early ’70s. Instead, sleep in their stuff, starting with the Penguin, a lightweight bag that converts from a single sleeping bag to a double bag in just a few quick steps.

When fully unzipped, the Penguin can be attached to a separate groundsheet stuffed with two sleeping pads to make a quilt-style setup that works for two. Attach optional hoods to each side of the Penguin and boom: double sleeping bag.

Because the groundsheet doesn’t weigh much, the Penguin offers a lightweight setup that mimics a top quilt, but can just as easily be used as a standard one-person sleeping bag when you’re solo in the backcountry.

7. Enlightened Equipment Accomplice 2-Person Quilt

Enlightened Equipment Accomplice 2-Person Quilt

Tech Specs:

  • Temperature rating: 0˚ to 50˚
  • Insulation: 850fp down
  • Weight: 1 to 3 lbs.

If your goal in the backcountry’s to shed as much weight as possible, consider a two-person quilt, a hood-less, zipper-less sleeping bag alternative that cuts weight and space but still provides premier warmth.

The Minnesota-made Accomplice is a great starting point: it’s customizable, so you can choose your temperature rating and length to find the ideal quilt. Each size and rating has its own weight specs, but the bottom line is going with a quilt saves precious ounces in your pack. When you’re on a long trip, that weight savings can add up to comfort and convenience quickly. 

The stock Accomplice comes in a bold red and charcoal colorway, but for more options, they also offer a custom Accomplice, where you can choose the color, down type and other features to fit your exact preferences.

8. Zpacks Twin Quilt

Zpacks Twin Quilt

Tech Specs:

  • Temperature rating: 5˚
  • Insulation: 900 fp goose down
  • Weight: 2 lbs 3 oz
  • Size: fits up to 6’2”
  • Pack size: 17” x 21”

If you’re a warm sleeper that needs more ventilation to sleep comfortably, check out the Twin Quilt from Zpacks. Available in 5℉, 20℉, and 35℉ variations, the ultralight Twin Quilt will keep you warm and comfortable year-round.

The Twin Quilt uses premium 900 fp goose down for insulation, and employs vertical baffles on the upper body to keep the down from migrating to the sides.

Cold spots won’t be an issue, as there are no sewn-through seams and the compartments are tightly spaced to keep the down evenly distributed. The compartments are overstuffed with 30% more down than necessary to maintain maximum loft and account for future down compression.

The Twin Quilt has a neck pillow that blocks the gap between your neck, and you can cinch the elastic cord tight around your neck to block out drafts. You can also strap the back side together when it’s really cold, and each sleeper can untuck their side to vent or kick out a leg if they start feeling too warm.

The shell and liner are both treated with a DWR finish to resist moisture and rain spray, and the black fabric on the inside is quick drying. The Twin Quilt comes with a roll top dry bag, so it’s easy to compress and squeeze into your pack.

9. REI Co-op HunkerDown 20 Double Sleeping Bag

. REI Co-op HunkerDown 20 Double Sleeping Bag

Tech Specs:

  • Temperature rating: 20˚
  • Insulation: 600-fill-power down
  • Weight: 6 lbs. 11 oz.

Firmly in the car camping category of double sleeping bags is REI’s HunkerDown, a versatile bag designed to keep couples happy and warm in the great outdoors.

Finally, oversized hoods that can be retracted and adjusted separately make it easy to find your cozy spot without interfering your partner’s pillow vibe. The down filler and long dimensions also make this ideal for couples of any size.

“I would have to say that the HunkerDown is one of the best sleep bags that I’ve owned,” said one reviewer in Atlanta. “It is quite warm, spacious, and the designers truly thought of everything.”

10. TETON Sports Mammoth 20 Degree Double Sleeping Bag

mammoth double sleeping bag

Tech Specs:

  • Temperature rating: 20˚
  • Insulation: SuperLoft Elite Hollow Fiber
  • Weight: 14 lbs.
  • Size: 94″ x 62″
  • Pack size: 27″ x 14″ x 14″

In fact, TETON’s signature lifetime warranty applies to craftsmanship and materials no matter where you purchase your bag.

True to its name, the Mammoth is large and in charge, making it ideal for camping trips with no weight or space restrictions. It’s not a backcountry option, but if comfort’s your priority in the outdoors, you’ll come to appreciate the Mammoth’s cozy bulkiness.

11. The North Face Eco Trail Bed Double 20 Sleeping Bag

The North Face Eco Trail Bed Double 20 Sleeping Bag

Tech Specs:

  • Temperature rating: 20˚
  • Insulation: recycled polyester
  • Weight: 7 lbs. 8 oz. (regular)
  • Pack size: 13″ X 24″

You can feel good about investing in the Eco Trail Bed Double: the shell, lining and insulation are all recycled polyesters, making it one of the most sustainable double bags on the market. You won’t pay more for the greener materials, either, and at this price point the Eco Trail Bed’s one of the more budget-friendly bags available.

The cut of the bag is roomy but it’s not overly heavy; there are enough features, like a sewn-in phone pocket, to make the bag versatile but still simple where it matters. Its weight and pack size make it ideal for camping, and when combined with something like the Exped MegaMat Max 15 Duo Sleeping Pad, makes for a cozy sleeping setup in the wild.

12. Big Agnes Dream Island 15˚

Big Agnes Dream Island 15 Degree Sleeping Bag

Tech Specs:

  • Temperature rating: 15˚
  • Insulation: FireLine™ Max Synthetic Insulation
  • Weight: 7 lbs. 9 oz.
  • Pack size: 10.5″ x 11.5″

The “dream” in Dream Island 15˚ comes from its ease of use and comfort: a sleeve beneath the bag makes it easy to stay connected to your sleeping pad (or pads) throughout the night, and a contoured shape offers the same space to move you’d find at home.

The recycled synthetic insulation acts closer to down than you’d expect, and the warmth-to-cost ratio of this bag is hard to beat. And though it weighs about as much as other bags in its class, it packs down smaller and the filling stays spread evenly throughout your backcountry trips.

“We did a lot of looking around for a double bag and we are so happy we landed on this one,” said one Dream Island 15˚ owner. “We do a lot of tent camping with a multi season double sleeping mat and this makes for a great sleep.”

13. The North Face Dolomite One Double Bag

The North Face Dolomite One Double Bag

Tech Specs:

  • Temperature rating: 20˚
  • Insulation: Heatseeker Eco synthetic fibers
  • Weight: 8 lbs 5 oz
  • Size: fits up to 6’
  • Pack size: 13” x 24”

When you’re looking for three-season warmth on a budget and weight doesn’t matter, look no further than Dolomite One Double from The North Face.

The Dolomite One Double is one of the most popular double sleeping bags on the market for car campers. The bag’s Heatseeker™ Eco insulation delivers a great warmth-to-weight ratio that’s fairly compressible, and the synthetic fibers are composed of 30% recycled material.

The Dolomite One Double features full-length zippers on both sides, and you can completely unzip the top to create a large, insulated camp blanket. The bag also features a wraparound footbox zipper that allows the bag to lie flat.

If you’re a fan of this old school style but prefer genuine down over synthetic insulation, check out the Dolomite Double Down. The Dolomite Double Down shaves off almost three pounds and compresses smaller with water-repellant 550 fp ProDown™.

Considering the Dolomite Double Down is priced similarly to the best synthetic double sleeping bag, the Big Agnes Cabin Creek 15˚, it’s a hell of a deal for a down sleeping bag.
