Recommended Ultralight 2 Person Quilts & Bags
From a technical perspective, a double sleeping bag for backpacking, or better yet a 2 person quilt, is advantageous because it allows for the sharing of body heat. Two partners in a 30° double may be as warm or warmer than separating out into two separate 20-25°s. What’s more, by eliminating redundant sidewall materials, a double sleeping bag or quilt is almost always slightly lighter weight than two comparably rated singles. Combined, these benefits yield some nice weight savings.
But perhaps most important of all, you can’t put a price on snuggles. If you frequently hike with a romantic partner, we encourage you to consider packing a 2 person quilt or double sleeping bag for backpacking. These are the four best options to consider, and we strongly encourage you to choose a quilt over a sleeping bags:
- Best 2 Person Quilt: Enlightened Equipment Accomplice
- Lightest 2 Person: Zpacks Twin Quilt
- Least Expensive 2P Quilt: Zenbivy Light Quilt Double
- Lightest Double Sleeping Bag: Feathered Friends Spoonbill UL 2
- Warmest Double Sleeping Bag: Sea to Summit Spark

Comparison Table: Double Sleeping Bag & Quilt vs Two Singles
As the below table demonstrates, a double quilt is overall preferable to two singles. That’s because a double is less expensive, lighter weight, and warmer due to shared body heat. While two solo quilts have more total down fill, it is not enough to overcome the advantage of shared body heat, and also creates more stowed bulk. That being said, even for duos who are used to sharing a bed, the separation and the redundancy of two separate quilts may be preferable. Ultimately, go with whatever setup is more comfortable for you!

- * Uncompressed Down Volume: This statistic correlates strongly with relative total warmth by measuring the volume of insulation stuffed into its the baffles. A garment with a higher number is very likely to feel warmer than a garment with a lower number
- **Uncompressed Down Volume per ounce of total garment weight: This statistics correlates strongly with warmth-to-weight ratio. It measures how much total insulation there is per ounce of total garment weight, which factors in shell, zipper, insulation, etc. It helps determine how effectively a sleeping bag or quilt uses its mass to insulate. A higher number means a higher warmth to weight ratio, but not necessarily a higher total warmth
The Best 2 Person Quilt For Backpacking
Enlightened Equipment Accomplice 2 Person Quilt
If you and your partner are shopping for a 2 person sleep system, the first model to consider is Enlightened Equipment Accomplice. Constructed with 950 fill power down and efficient 10d shell fabric, it’s ultralight, ultra warm, surprisingly affordable, and much more user-friendly than a double sleeping bag. This is Alan & Alison’s preferred backpacking quilt, and they have used the Accomplice to great effect on throughout North America, South America, and Europe.
The backless nature of a 2-person quilt requires using higher R-value sleeping pad(s), ideally R-4+, to insulate from below. But otherwise, the backless-ness is massively beneficial. It allows the quilt to be used more like a blanket, such that partners can spread out a bit wider without being strictly limited to the confiningly narrow interior dimensions of a double bag. If one partner sleeps warmer, they can easily ventilate. And it has a really nice draft blocker feature that prevents cold air from entering at the top gap formed in between sleepers’ shoulders.
Lastly, the stats below reflect a fully optimized version with top quality down fill. But sub in 850 for 950 and you save $130.
- Price: $745 (budget version for $560)
- Total Weight: 34.9 o
- Shell Weight: 10.0 oz
- Fill Weight: 24.9 oz
- Fill Power: 950
- Uncompressed Down: 23655 (in³)
- Uncompressed Down/Garment Weight: 678 in³/oz
- Girth at Shoulders: 86″
- Pros: Shared body heat. Ultralight. High warmth-to-weight ratio. Less confining than sleeping bag. Draft collar. Easy venting. Good value. Best in class materials. U-Shaped Baffles
- Cons: Requires use of higher R-value sleeping pad.
Zpacks Twin Quilt
The Zpacks Twin Quilt takes most of what we love about its predecessor, the Enlightened Equipment Accomplice, and shaves off a few features to achieve a slightly higher warmth-to-weight ratio on spec, all for $100 less. Plus it comes with a complimentary Dyneema dry bag. What a deal!
However, part of the cost savings compared to EE Accomplice is that it has over four ounces (~20%) less total down fill insulation. While still completely adequate, it relies more on shared body heat to create enough warmth to stand up to its rating. While fine for most, two cold sleepers might think of this more like a 25F than a 20F.
Our biggest knock against the Twin Quilt is that it lacks a draft collar. On solo quilts, draft collars hardly matter. But for doubles, a massive gap forms in between the shoulders of the sleepers, and no draft collar means an extra dose of heat loss. Though on warm nights, an extra dose of ventilation ain’t all bad.
- Price: $579
- Total Weight: 27.9
- Shell Weight: 7.6 oz
- Fill Weight: 20.3 oz
- Fill Power: 950
- Uncompressed Down: 23655 (in³)
- Uncompressed Down/Garment Weight: 678 in³/oz
- Girth at Shoulders: 86″
- Pros: Shared body heat. Ultralight. High warmth-to-weight ratio. Less confining than sleeping bag. Easy venting. Best value. Best-in-class materials.
- Cons: No draft collar. Requires use of higher R-value sleeping pad. Slightly underfilled relative to peer group. Complimentary DCF dry bag.
Zenbivy Light Quilt Double
For the least expensive performance double quilt, but one that is still comfier and superior to all double sleeping bags, go with the Zenbivy Light. Benefits include the softer-than-most shell fabric, lower-than-average price, and wider-than-average girth, What’s more, it couples with a sheet/hood hybrid add-on that fully eliminates drafts, increases comfort, and insulates the head for one additional pound. Downsides include the use of duck down, which costs less because it doesn’t hold up to repeated compressions cycles and re-loft as well as goose down, meaning a shorter useable lifespan, and also it smells worse when wet.
- Price: $499
- Total Weight: 47.0
- Shell Weight: 20.1 oz
- Fill Weight: 26.9 oz
- Fill Power: 800 duck
- Uncompressed Down: 21520 (in³)
- Uncompressed Down/Garment Weight: 458 in³/oz
- Girth at Shoulders: 92″
- Pros: Shared body heat. Lightweight. Softer fabric. High warmth-to-weight ratio. Less confining than sleeping bag. Easy venting. Best value. Optional sheet add-on.
- Cons: Heavier than other 2p quilts, lower warmth-to-weight. Duck down has shorter life than goose down, smells worse when wet.
The Best Double Sleeping Bag For Backpacking
Feathered Friends Spoonbill
If you’re shopping for a double sleeping bag for backpacking and won’t use a quilt, make Feathered Friends Spoonbill UL 2 your first look. It’s lightweight and made with incredibly high quality materials – 950 fill power down and 10d Pertex Endurance shell fabric. Two half length side zippers offer independent sources of ventilation to regulate differing body temperatures.
Notably, this design is something like a quilt-sleeping-bag hybrid, with the top and sides being insulated, and the bottom being a thin layer of durable Dyneema fabric that merely prevents drafts. As such, we suggest pairing it with an insulated sleeping pad rated to R-value 4+. Though it’s not given a temp rating, we’d call this a 20F bag, as it has a comparable amount of down to the aforementioned Zpacks and Enlightened Equipment quilts, but less than the Sea to Summit Spark 15F.
- Price: $999
- Total Weight: 38.3 oz
- Shell Weight: 15.3 oz
- Fill Weight: 23.0 oz
- Fill Power: 950
- Uncompressed Down: 21850 in³
- Uncompressed Down/Garment Weight: 570 in³/oz
- Girth at shoulder (counting underside): 104″
- Pros: Shared body heat. Ultralight. High quality materials. Quilt-like.
- Cons: Expensive. More confining, lower warmth-to-weight ratio than a 2 person quilt.
Sea to Summit Spark 15 Double Sleeping Bag
For the warmest option on the market, we recommend Sea to Summit Spark 15. Compared its peers, Spark 15 Double is warmer, and uses higher quality lightweight materials – 850 fill power, 10d shell fabric.
It also comes with a bevy of nice features, including built-in sleeping pad attachment straps, and the best zipper plow we’ve ever used; it virtually never snags or gets stuck. Both sides of this 2 person sleeping bag feature a double separating zipper that can be used effectively for ventilation as needed. Like the rest of Sea to Summit’s Spark sleeping bag line, the double is an exemplary design.
Notably, it only comes in a 15f Long configuration, and is likely too warm for summer use, considering shared body heat.
- Price: $999
- Total Weight: 54.4 oz
- Shell Weight: 19.7 oz
- Fill Weight: 34.7 oz
- Fill Power: 850
- Uncompressed Down: 29495 in³
- Uncompressed Down/Garment Weight: 542 in³/oz
- Girth at shoulder (counting underside): 105″
- Pros: Shared body heat. Relatively lightweight. High quality materials. Comes with pad attachment straps. Best zipper plows. Draft blocker. Double separating zippers on both sides for venting.
- Cons: Expensive. Only available in 20F long configuration. Too warm for summer use. More confining, lower warmth-to-weight ratio than a 2 person quilt.
Double Sleeping Bag & 2 Person Quilt Buyer Considerations
Is A Double Sleeping Bag or 2 Person Quilt Right For You & Your Partner?
For starters, you should only choose a double sleeping bag or quilt to use with a partner who you are very comfortable with. Most 2 person sleeping bags attempt to approximate a double bed in terms of width, meaning they are quite narrow. If you are used to sleeping in a queen or king, prepare to be a lot physically closer to your partner. This may reduce your sleep quality. If you already sleep with another in a double bed, a double sleeping bag will likely be an easy transition.
2 person quilt vs double sleeping bag
It follows that because quilts are overall superior to sleeping bags, a 2 person quilt is better than a double sleeping bag. As a refresher, this is because quilts are less confining, lighter weight, better ventilated (if desired), and have a higher warmth-to-weight ratio. They concentrate insulation above and to the sides of the user, while effectively relying on a high R-value sleeping pad to keep you warm from beneath. And no, when used properly, they aren’t drafty.
The delta between 2 person quilts and double sleeping bags is even higher than with singles. Primarily, that’s because they allow you to spread out more comfortably. But also, because they can more easily be ventilated on warm nights, while still reaping all of the same shared heat benefits on cold nights.
Why a 2 person sleeping bag is warmer than 2 comparably rated singles
When two partners share one quilt or sleeping bag, they share radiant heat. Both parties’ body heat warms the other, and the space in between. Therefore, two people sharing one microclimate is more effective than two people each in their own microclimate. This is similar to why mittened fingers feel warmer than gloved fingers. Four fingers in a mitten share heat with each other, while gloves separate each finger out and prevent radiant heat sharing.
As such, two people sharing a 30 degree double sleeping bag or quilt may feel comparably warm to each individual in a 20 or 25 degree solo sleeping bag.
Who Should Avoid A 2 Person Sleeping Bag or Quilt
- People who don’t already sleep next to each other, seeing how it goes for the first time in the backcountry is a bad idea
- Two larger partners. If both partners are taller and/or wider than average, sharing a one-size-fits-most double may not be spacious enough
- Restless sleepers. If you roll and/or thrash about in the night, you will likely come into greater contact with your partner, disrupting their sleep.
- Starkly different body temperatures during sleep. It’s normal for two partners to sleep at different temperatures. But if one partner sleeps much much warmer than average and the other sleeps much much colder than average, it may force a compromise that both parties tolerate, but neither prefers.
Conclusion
Thank you for reading our guide to the best double sleeping bag and quilt for backpacking, where we hope you and your partner found your new favorite 2 person sleep system. When camping with a partner, we specifically prefer a 2 person quilt, because it’s less confining than a 2 person sleeping bag, while still offering the benefits of shared warmth. But a double sleeping bag works well too. Happy camping!
