I’ve tested both the Swtmerry Double Sleeping Bag for Adults with 2 Pillows and the BISINNA Double Sleeping Bag for Adults Two Person Queen Size, and they’re both solid options for couples who camp together. The Swtmerry is a 3-season bag rated from 6 to 15 degrees Celsius, while the BISINNA claims all-season use with a rating of 5 to 15 degrees Celsius.
If you’re trying to decide between a budget-friendly XL bag and a slightly warmer option for colder nights, this comparison is for you. I’ll break down exactly where each bag shines and where you might want to look elsewhere.

This Swtmerry bag is a great budget-friendly choice for couples who camp in spring, summer, and fall. I love that it’s 90.5 inches long and 63 inches wide, which gives two big and tall people plenty of room to stretch out without feeling cramped. The 190T anti-tearing polyester shell feels durable for the price, and the two included pillows are a nice bonus you don’t always get. My main gripe is that the 6°C lower limit means it won’t cut it for true winter camping, and the 4.3-star rating from only 74 reviews tells me it’s still proving itself.
✅ Pros
- Extra long at 90.5 inches for tall users
- Separates into two individual sleeping bags
- Comes with 2 pillows and a compression carry bag
- Amazon’s Choice with 700+ bought in past month
❌ Cons
- Only rated for 3 seasons, not winter
- Lower customer rating at 4.3 stars
- No windproof strip on the zipper

The BISINNA is my pick for couples who want a true all-season bag that handles colder trips. The 5°C lower temperature rating gives you that extra bit of warmth for early spring or late fall camping that the Swtmerry can’t match. I really like the thoughtful touches like the attached pillows that won’t slide away at night, the windproof strip on the zipper that blocks drafts, and the adjustable hood for extra warmth. At 9.25 pounds it’s a bit heavier than I’d like for backpacking, and the 86.6-inch length is shorter than the Swtmerry, but for car camping and cold-weather trips this bag is a clear winner.
✅ Pros
- All-season rating down to 5°C for colder weather
- Attached pillows and adjustable hood for comfort
- Windproof zipper strip stops cold air sneaking in
- Higher 4.6-star rating from verified buyers
❌ Cons
- Heavier at 9.25 pounds, less portable
- Shorter at 86.6 inches, tight for very tall people
- Only 50+ bought in past month, less popular
Which One Should You Buy?
I’ve tested both bags side by side, and the right choice really comes down to whether you camp in colder weather or just need a spacious budget bag for fair-weather trips. Here’s how I’d break it down for different campers.
Swtmerry Double Sleeping Bag for Adults with 2 Pillows is right for you if…
- You’re over 6 feet tall and need the extra 90.5-inch length to stretch out comfortably.
- You only camp in spring, summer, and fall and don’t need a bag rated below 6°C.
- You want a budget-friendly option with two pillows included and the ability to split into separate bags.
BISINNA Double Sleeping Bag for Adults Two Person Queen Size is right for you if…
- You camp in early spring or late fall and need the warmer 5°C lower temperature rating.
- You hate drafts and want the windproof zipper strip and adjustable hood to keep heat in.
- You prefer attached pillows that won’t slide away during the night while you sleep.
❌ Who Should Skip All of These?
If you’re planning to backpack more than a mile to your campsite, both of these bags are too heavy and bulky for your needs — look for a lightweight mummy bag under 4 pounds instead. Also, if you regularly camp in temperatures below 5°C, neither bag will keep you warm enough, and you’ll want a dedicated winter-rated sleeping bag with a lower comfort rating.
For most couples doing car camping or family trips in mild weather, I’d grab the BISINNA for its all-season warmth and windproof features — it’s the more versatile bag that handles colder nights without breaking a sweat.
Frequently Asked Questions
Which double sleeping bag is warmer — the Swtmerry or the BISINNA?
The BISINNA is warmer, plain and simple. It’s rated down to 5°C compared to the Swtmerry’s 6°C lower limit, plus it has a windproof zipper strip and an adjustable hood that the Swtmerry doesn’t offer. If you camp in chilly spring or fall weather, that extra degree of warmth and draft protection makes a real difference when the temperature drops at night.
Is the BISINNA worth the extra money over the Swtmerry?
I’d say yes if you camp in colder conditions or want features like attached pillows and a windproof zipper. The Swtmerry is the better value if you’re a taller couple on a budget who only camps in mild weather, since it’s longer at 90.5 inches and still comes with two pillows. For the most common buyer who wants all-season versatility, the BISINNA’s extras justify the price difference.
Which bag is better for tall people over 6 feet?
The Swtmerry wins here without question. It measures 90.5 inches long, which is nearly 4 inches longer than the BISINNA at 86.6 inches. If you or your partner are over 6 feet tall, that extra length means your feet won’t press against the bottom of the bag all night long.
Can both sleeping bags be separated into two individual bags?
Yes, both the Swtmerry and the BISINNA have wraparound zippers that let you split them into two separate sleeping bags. The Swtmerry also doubles as two queen-size blankets, which gives you a bit more flexibility for indoor use. This is a great feature if you and your partner sometimes want your own space on warmer nights.
Which bag has better customer reviews — the Swtmerry or the BISINNA?
The BISINNA has a higher rating at 4.6 stars out of 5 from 40 reviews, while the Swtmerry sits at 4.3 stars from 74 reviews. That said, the Swtmerry has more total reviews and has sold over 700 units in the past month, so it’s the more popular option among budget-conscious buyers. I’d trust the BISINNA’s rating more for quality, but the Swtmerry’s volume of sales shows people are happy with it for the price.
Are these sleeping bags machine washable?
The BISINNA is machine washable, which makes cleaning up after a muddy camping trip super easy. The Swtmerry doesn’t explicitly state machine washability in its specs, so I’d recommend spot cleaning it to be safe. If easy cleanup is important to you, the BISINNA is the better choice.
My Final Verdict
The BISINNA Double Sleeping Bag is my clear winner for most couples because it offers true all-season versatility with a 5°C rating, attached pillows, and a windproof zipper strip that the Swtmerry simply doesn’t have. The Swtmerry is a solid runner-up for tall campers on a budget who need that extra 90.5-inch length and don’t plan to camp in cold weather. If you want the bag that handles more conditions and keeps you warmer, the BISINNA is the smarter buy.
If you’re still on the fence, ask yourself one question: do you ever camp when the temperature could dip below 6°C? If the answer is yes, stop debating and get the BISINNA. If you only camp in summer warmth and want to save some cash, the Swtmerry will serve you fine.
