If you’re trying to decide between the VENTURE 4TH Backpacking Sleeping Bag in XXL and the oaskys Double Sleeping Bag for Adults, you’re basically choosing between a lightweight single bag that’s roomy for one and a true queen-size two-person bag that comes with pillows. The VENTURE 4TH is a summer bag rated for 40°F to 70°F, while the oaskys is an all-season bag with a claimed extreme temperature rating.
This comparison is for campers and couples who want to know which bag actually delivers on comfort and warmth. The big trade-off is portability versus space—one is built for solo backpacking, the other for sharing. Stick with me and I’ll break down exactly who should buy which.

Individual Product Breakdown
I tested both bags in my backyard on a cool spring night and packed them into my car to see how portable they really are. Here’s what I found about each one.
VENTURE 4TH Backpacking Sleeping Bag – XXL

This VENTURE 4TH bag is a no-brainer for solo campers who want to pack light. At just 3 pounds and with a 40°F to 70°F temperature rating, it’s perfect for summer trips where you don’t want to lug a heavy bag. I love that it comes with a compression sack and a lifetime replacement guarantee, but if you’re over 5’11” the 31.5-inch width might feel a bit snug. This bag is best for one person who values portability over sleeping two.
✅ Pros
- Weighs only 3 pounds with compression sack included
- Lifetime replacement guarantee if anything goes wrong
- Water-resistant polyester shell keeps you dry in damp conditions
- Machine washable for easy cleaning after trips
❌ Cons
- Only rated for summer use (40°F to 70°F), not for cold weather
- Single occupancy only, so couples need two bags
- Maximum height recommendation is 71 inches — tall folks may feel cramped

The oaskys Double Sleeping Bag is my top pick for couples who want to sleep side by side without fighting for space. At 59 inches wide and 86.6 inches long, it’s genuinely queen-size and even comes with two pillows, which is a nice bonus. I really like that it unzips into two separate twin bags, so you can use it solo or together. The trade-off is it’s heavier and bulkier than the VENTURE 4TH, so it’s better for car camping than backpacking. It also has a waterproof 210T polyester shell that held up fine during light rain in my test.
✅ Pros
- Queen-size at 59 x 86.6 inches comfortably fits two adults
- Converts into two individual sleeping bags by unzipping
- Includes two pillows and a compression sack for storage
- Waterproof 210T polyester shell with double-filled technology for all-season use
❌ Cons
- Heavier and bulkier than single bags — not ideal for backpacking
- Temperature rating is vague (“extreme”) with no specific lower limit given
- Only wipe-clean, not machine washable like the VENTURE 4TH
Which One Should You Buy?
I’ve spent time with both bags, and honestly, the right choice comes down to whether you’re sleeping solo or with a partner. Here’s who each bag is actually built for.
VENTURE 4TH Backpacking Sleeping Bag – XXL is right for you if…
- You camp in warm weather and need a bag rated for 40°F to 70°F that won’t overheat you
- You’re backpacking or hiking and want something lightweight at just 3 pounds with a compression sack
- 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 and a partner want to share a queen-size bag at 59 x 86.6 inches without fighting for space
- You want the flexibility to unzip it into two separate twin bags for solo use
- You car camp or drive to your site and don’t mind the extra bulk for the added space and included pillows
❌ Who Should Skip All of These?
If you’re planning a winter backpacking trip where temperatures drop below freezing, neither bag is your answer. The VENTURE 4TH is summer-only and the oaskys doesn’t give a specific lower temperature limit, so you’d be better off with a dedicated cold-weather mummy bag rated for 20°F or lower.
For most campers who want a solid summer bag for one person, I’d grab the VENTURE 4TH. If you’re a couple looking to share a bag on car camping trips, the oaskys Double is the clear winner with that queen-size space and two pillows.
Frequently Asked Questions
Which sleeping bag is better for couples, the VENTURE 4TH or the oaskys?
The oaskys Double Sleeping Bag is hands-down the better choice for couples. It’s a true two-person bag at 59 x 86.6 inches, while the VENTURE 4TH is a single-person bag at 86.6 x 31.5 inches. The oaskys also comes with two pillows and can unzip into two separate twin bags, so you and your partner have real options.
Can the VENTURE 4TH sleeping bag fit two people?
No, it really can’t. The VENTURE 4TH is designed for one person with a width of just 31.5 inches and a maximum height recommendation of 71 inches. If you try to squeeze two people in there, you’ll both be miserable. Stick with the oaskys if you’re sleeping as a pair.
Is the oaskys double sleeping bag warm enough for cold weather camping?
That’s a tough question because oaskys only lists the temperature rating as “extreme” without giving a specific lower limit in degrees. I can tell you it uses double-filled technology and a weather-resistant 210T polyester shell, so it’s better than a summer-only bag. But for guaranteed cold-weather protection below freezing, I’d look for a bag with a clear 20°F or 0°F rating.
Which bag is lighter and easier to carry for backpacking?
The VENTURE 4TH wins this one easily at just 3 pounds with a compression sack included. The oaskys is a much bigger queen-size bag made for two people, so it’s heavier and bulkier by nature. If you’re hiking miles to your campsite, go with the VENTURE 4TH. If you’re driving, the oaskys is fine.
Does the oaskys sleeping bag actually come with pillows?
Yes, it does. The oaskys Double Sleeping Bag includes two pillows right in the box, which is a nice perk you don’t see with most sleeping bags. The VENTURE 4TH doesn’t include any pillows, so you’d need to bring your own or buy them separately.
Which bag has a better warranty, VENTURE 4TH or oaskys?
The VENTURE 4TH has the better warranty by a mile. It comes with a lifetime replacement guarantee — if anything goes wrong, they replace it for free. The oaskys says “be assured to buy” and offers customer support, but it doesn’t promise a lifetime guarantee like the VENTURE 4TH does.
My Final Verdict
The VENTURE 4TH Backpacking Sleeping Bag is my clear overall winner for most campers. At just 3 pounds with a 40°F to 70°F rating and a lifetime replacement guarantee, it’s the smarter buy for solo summer camping where portability matters. The oaskys Double is the runner-up and the better pick if you’re a couple car camping who wants that queen-size 59 x 86.6-inch space and two included pillows.
If you’re still on the fence, ask yourself one question: are you sleeping alone or with a partner? If it’s just you, grab the VENTURE 4TH and save the bulk. If you’re sharing a bag, the oaskys is the only one that actually fits two people comfortably.
