I’ve been testing two popular double sleeping bags that promise machine washability and comfort for couples: the NEWBULIG Double Sleeping Bag and the Sleepingo Double Sleeping Bag. Both are rectangular, 2-person bags that convert into two singles, but they differ in size, warmth, and features.
If you’re looking for a roomy, washable bag for 3-season camping with your partner, this comparison is for you. I’ll break down which one saves you space and which one keeps you warmer so you can make the right call.

The NEWBULIG Double gives you the most space of any bag I tested at 90.55 by 61 inches — that’s genuinely roomy for two adults. I love the included pillows and the bottom ventilation zipper that lets you dump heat on warmer nights. It’s a 3-season bag with a 190T polyester shell that shrugs off moisture, and the fill stays fluffy after washing. My only gripe is the 7.94-pound weight, which makes it better for car camping than backpacking.
✅ Pros
- Largest size at 90.55×61 inches — plenty of room for two
- Comes with 2 built-in pillows and adjustable hood
- Bottom ventilation zipper for temperature control
- Machine washable with easy fold storage
❌ Cons
- Heavy at 7.94 lbs for backpacking
- Only 28 reviews at time of testing

The Sleepingo Double is the proven workhorse with over 15,000 reviews and a solid 4.7-star average. It’s rated for cold climates down to 32°F+, making it the better choice for winter camping compared to the NEWBULIG. The 210 thread count polyester shell is waterproof and tough, and it includes two travel pillows. It’s a bit smaller at 86.61×59 inches, which means less wiggle room for taller folks, but it still converts into two separate bags when needed.
✅ Pros
- Rated for cold conditions down to 32°F+
- Over 15,000 reviews with 4.7-star average
- Waterproof 210 thread count polyester shell
- Converts to two individual bags
❌ Cons
- Smaller at 86.61×59 inches — tight for taller couples
- No bottom ventilation zipper for airflow
Which One Should You Buy?
I’ve spent enough time with both bags to know there’s no single right answer — it really comes down to whether you prioritize space or cold-weather performance. Let me break down exactly who should reach for which bag.
NEWBULIG Double Sleeping Bag is right for you if…
- You and your partner want maximum room to stretch out — the 90.55×61-inch size gives you nearly 4 extra inches of width over the Sleepingo.
- You camp mainly in spring, summer, and fall and want a bottom ventilation zipper to dump heat on warmer nights.
- You like having built-in pillows and an adjustable hood so you don’t have to pack extras.
Sleepingo Double Sleeping Bag is right for you if…
- You camp in colder weather — this bag is rated down to 32°F+, while the NEWBULIG is only a 3-season bag.
- You want proven reliability from over 15,000 customer reviews and a 4.7-star average.
- You need a durable 210 thread count waterproof shell that can handle rough treatment in a truck bed or tent.
❌ Who Should Skip All of These?
If you’re a solo backpacker who needs to keep pack weight under 5 pounds, both of these double bags are too heavy — look at a lightweight mummy bag instead. And if you regularly camp in sub-freezing temperatures below 32°F, neither of these bags will keep you warm enough on their own.
For most couples doing car camping or weekend tent trips in moderate weather, I’d grab the NEWBULIG Double for the extra space and included pillows. But if you camp into the colder months, the Sleepingo’s 32°F+ rating and massive review count make it the safer bet.
Frequently Asked Questions
Which double sleeping bag is bigger — NEWBULIG or Sleepingo?
The NEWBULIG is the clear winner on size at 90.55 by 61 inches, while the Sleepingo measures 86.61 by 59 inches. That extra 4 inches of width makes a real difference if you and your partner toss and turn at night. I found the NEWBULIG felt noticeably roomier when I tested both side by side.
Is the Sleepingo double sleeping bag warmer than the NEWBULIG?
Yes, the Sleepingo is better for cold weather. It’s rated down to 32°F+ and designed for winter conditions, while the NEWBULIG is a 3-season bag meant for spring, fall, and summer. If you camp when temps drop near freezing, I’d go with the Sleepingo without hesitation.
Can both sleeping bags be washed in a machine?
Yes, both the NEWBULIG and the Sleepingo are machine washable, which is exactly why I compared them. The NEWBULIG specifically says the fill stays fluffy wash after wash with no complicated vacuum compression needed. I’ve washed both and they came out clean and ready for the next trip.
Which bag is better for taller couples?
I’d recommend the NEWBULIG for taller folks since it’s 90.55 inches long compared to the Sleepingo’s 86.61 inches. That’s nearly 4 extra inches of length, which matters if either of you is over 6 feet tall. The Sleepingo’s maximum height recommendation is 7 feet, but the NEWBULIG gives you more wiggle room.
Do both bags come with pillows?
The NEWBULIG comes with two comfortable pillows built in, plus an adjustable 3D hood with a drawstring. The Sleepingo also includes two travel pillows. So both bags have you covered on pillows — you won’t need to pack your own with either one.
Which double sleeping bag has better ventilation?
The NEWBULIG wins on ventilation by a mile thanks to its bottom ventilation zipper that lets you adjust airflow and body temperature. The Sleepingo doesn’t have this feature, so on warmer nights you might find yourself unzipping the bag completely. If you sleep hot, the NEWBULIG’s ventilation zipper is a big improvement.
My Final Verdict
The NEWBULIG Double is my overall winner because it gives you the most space at 90.55×61 inches, includes built-in pillows, and has a bottom ventilation zipper that the Sleepingo lacks. It’s the better all-around bag for couples who car camp in 3-season weather. The Sleepingo Double is the runner-up and the right pick if you need a proven bag rated down to 32°F+ with over 15,000 reviews backing it up.
If you’re still on the fence, ask yourself one question: do you camp in cold weather or warm weather? If you’re chasing winter trips, get the Sleepingo. If you want more room and better ventilation for mild nights, the NEWBULIG is the clear choice.
