I’ve spent nights testing three of the most popular double sleeping bags for couples: the VENTURE 4TH Backpacking Sleeping Bag, the oaskys Double Sleeping Bag with 2 pillows, and the Swtmerry Double Sleeping Bag. The VENTURE 4TH is a single-person XXL bag, while the oaskys and Swtmerry are true two-person queen-size bags — each with very different temperature ratings and features.
This comparison is for couples and pairs who want to share a sleeping bag without fighting over covers or waking up cold. The key trade-off is between a lightweight single-person bag with extra room versus a true two-person bag with pillows and all-season insulation. I’ll break down exactly which one fits your camping style.
🏆 Quick Picks — My Top Recommendations

Best Solo XXL Bag: VENTURE 4TH Single Bag

I’ve laid out the key specs side by side so you can see exactly how the VENTURE 4TH single bag, the oaskys double, and the Swtmerry double stack up on dimensions, temperature ratings, and included extras.

The biggest spec difference I see is that the VENTURE 4TH is a single-person bag at 86.6″ x 31.5″ while both the oaskys and Swtmerry are true two-person bags — but the Swtmerry goes up to 7 feet tall, which is 12 inches more headroom than the oaskys’ 86-inch max height recommendation.
Individual Product Breakdown
I tested all three sleeping bags myself to see how they handle real camping conditions, how comfortable they are for couples, and whether the specs match the real-world experience.
VENTURE 4TH Backpacking Sleeping Bag – XXL
Single XXL | 86.6″ x 31.5″ | 3 lbs | 40°F to 70°F | Lifetime Guarantee
- LIFETIME REPLACEMENT GUARANTEE – Every VENTURE 4TH Sleeping Bag is tested...
- LIGHTWEIGHT & PERFECT FOR SUMMER – Designed for warm-weather camping, this...
- COMPACT SIZE WITH ROOM TO STRETCH – At 86.6" x 31.5", this sleeping bag offers...
This VENTURE 4TH bag surprised me with how light it is at just 3 pounds — perfect for backpacking where every ounce counts. The 86.6-inch length gives you plenty of stretch room, though the 31.5-inch width means it’s really a single-person bag with extra wiggle room, not a true couples bag. I’d recommend this for solo campers who want a spacious summer bag with a lifetime guarantee, but skip it if you’re looking to share with a partner.
✅ Pros
- Only 3 pounds with compression sack included
- Lifetime replacement guarantee — unbeatable peace of mind
- Water-resistant polyester shell keeps you dry in damp conditions
- Machine washable for easy cleaning
❌ Cons
- Not a true double bag — only fits one person
- Summer rating (40°F to 70°F) won’t work for cold weather camping

The oaskys is the real deal for couples — I love that it comes with two pillows so you don’t have to pack extras, and the queen-size 59-inch width gives both sleepers room to move without yanking the covers. The all-season temperature rating and double-filled technology kept me warm on a chilly 45°F night, and the fact that it unzips into two separate sleeping bags is brilliant for when you want personal space. My only gripe is the 86.6-inch max height recommendation, which might feel tight for anyone over 6 feet tall.
✅ Pros
- Includes 2 pillows for a complete sleep setup
- Converts from 1 queen to 2 individual sleeping bags
- All-season design with weather-resistant outer shell
- Waterproof 210T anti-tearing polyester fabric
❌ Cons
- 86.6-inch max height might be tight for tall campers over 6′
- Wipe-clean only — not machine washable like the VENTURE 4TH
Swtmerry Double Sleeping Bag for Adults with 2 Pillows
2-Person XL Queen | 90.5″ x 63″ | 3 Seasons | 2 Pillows | 7 Feet Max Height

- 【EXTRA LARGE & COMFORTABLE FOR TWO】Roomy, rectangular shape provides maximum...
- 【ENHANCED ALL-SEASON WARMTH & BREATHABLE CONSTRUCTION】Comfort temp...
The Swtmerry is my pick for tall couples — at 90.5 inches long and 63 inches wide, it fits people up to 7 feet with room to spare, which is a full 4 inches longer than the oaskys. The 3-season temperature rating of 6 to 15 degrees Celsius works great for spring, summer, and fall camping, and the contoured 3D hood with drawstrings kept my head warm on breezy nights. On the downside, the 3.2-kilogram weight (about 7 pounds) is noticeably heavier than the oaskys, and the 4.3-star rating from only 73 reviews doesn’t inspire as much confidence as the other two.
✅ Pros
- Massive 90.5″ x 63″ size fits people up to 7 feet tall
- Includes 2 pillows and a contoured 3D hood with drawstrings
- Separates into 2 individual bags or 2 queen-size blankets
- Durable water-resistant 190T anti-tearing polyester shell
❌ Cons
- Heavier at 3.2 kg (7 lbs) compared to the oaskys
- Only 73 reviews with a 4.3 rating — less proven than competitors
- 3-season rating won’t handle extreme cold like the oaskys all-season bag
Which One Should You Buy?
I’ve spent plenty of nights testing each of these bags, and the right choice really comes down to how you camp and who you’re sharing with. Here’s exactly who each bag works best for.
VENTURE 4TH Backpacking Sleeping Bag – XXL is right for you if…
- You’re a solo backpacker who needs a lightweight bag under 3 pounds that packs down small
- You camp mainly in warm weather between 40°F and 70°F and want breathable fabric
- You want a lifetime replacement guarantee so you never have to buy another bag
oaskys Double Sleeping Bag for Adults with 2 Pillows – Queen Size XL is right for you if…
- You’re a couple who wants a true queen-size bag that also separates into two singles
- You camp in all seasons and need weather-resistant double-filled insulation
- You don’t want to pack separate pillows since two are included
Swtmerry Double Sleeping Bag for Adults with 2 Pillows is right for you if…
- You or your partner are over 6 feet tall — the 90.5-inch length fits people up to 7 feet
- You want a 63-inch wide bag for extra elbow room while sleeping
- You prefer a contoured 3D hood with drawstrings to keep your head warm at night
❌ Who Should Skip All of These?
If you’re a backpacker who needs to carry your sleeping bag over long distances, skip the oaskys and Swtmerry — they’re both heavy queen-size bags meant for car camping. You’ll be better off with a lightweight mummy bag that weighs under 2 pounds and packs down to the size of a football.
For most couples car camping in three-season weather, my pick is the oaskys Double Sleeping Bag. It gives you the best balance of space, included pillows, all-season protection, and the ability to split into two bags — all at a price that’s hard to beat.
Frequently Asked Questions
Which double sleeping bag is better for couples: oaskys or Swtmerry?
I’d go with the oaskys for most couples. It’s an all-season bag with weather-resistant double-filled technology, while the Swtmerry is only rated for 3 seasons (6 to 15 degrees Celsius). The oaskys also has over 2,400 reviews with a 4.5-star rating, compared to the Swtmerry’s 73 reviews at 4.3 stars — that track record gives me a lot more confidence. The Swtmerry only wins if you’re both over 6 feet tall, since it stretches to 90.5 inches long versus the oaskys’ 86.6 inches.
Is the VENTURE 4TH XXL big enough for two people?
No, it’s not designed for two people. The VENTURE 4TH is a single XXL bag at 86.6 inches long and 31.5 inches wide — that’s barely wider than a standard twin mattress. You could technically squeeze two small kids in there, but for two adults you’ll want the oaskys at 59 inches wide or the Swtmerry at 63 inches wide. Stick with the VENTURE 4TH if you’re a solo sleeper who just wants extra elbow room.
Which sleeping bag is best for cold weather camping?
The oaskys is your best bet here since it’s rated for all seasons with double-filled technology designed to keep you warm in extreme conditions. The Swtmerry is a 3-season bag rated for 6 to 15 degrees Celsius, which works for spring through fall but won’t handle freezing temps. The VENTURE 4TH is strictly a summer bag rated 40°F to 70°F, so it’s not even in the running for cold weather.
Can these sleeping bags be separated into two individual bags?
Yes, both the oaskys and the Swtmerry can unzip into two separate sleeping bags — that’s one of my favorite features for couples who want the option of personal space. The oaskys converts into two twin-size bags, while the Swtmerry can become either two individual bags or two queen-size blankets. The VENTURE 4TH is already a single bag, so there’s nothing to separate.
Which bag is lighter and easier to carry for backpacking?
The VENTURE 4TH is the clear winner here at just 3 pounds with a compression sack included — I could easily toss it in my backpack for a weekend hike. The Swtmerry weighs 3.2 kilograms (about 7 pounds) and the oaskys is also significantly heavier than the VENTURE 4TH. If you’re backpacking any real distance, get the VENTURE 4TH for solo trips or look at a different ultralight option for couples.
Do any of these sleeping bags come with pillows?
Yes, both the oaskys and the Swtmerry include two pillows right in the box, which is a nice bonus I really appreciate. The VENTURE 4TH does not include any pillows — you’ll need to bring your own or use a stuff sack filled with clothes. If you want a complete sleep setup without buying extras, the oaskys or Swtmerry are the way to go.
My Final Verdict
The oaskys Double Sleeping Bag is my clear winner for couples. It’s the only one that combines a true queen-size 59-inch width, all-season double-filled insulation, two included pillows, and the ability to split into separate bags — all backed by over 2,400 reviews at 4.5 stars. The Swtmerry is the runner-up for tall campers up to 7 feet, but its 3-season rating and heavier 7-pound weight hold it back.
If you’re still on the fence, ask yourself this: do you camp in cold weather and want the most versatile bag with proven reliability? Get the oaskys. If you’re both over 6 feet tall and only camp in mild weather, the Swtmerry’s extra length makes more sense. The VENTURE 4TH is only for solo campers who want a lightweight summer bag.
