Picking between the VENTURE 4TH Backpacking Sleeping Bag and the oaskys Double Sleeping Bag for your next lightweight camping trip is tougher than it looks. Both are two-person bags with similar dimensions (86.6 inches long by 59 inches wide), but they have very different strengths for different kinds of campers.
I’ve spent time digging into the specs of both bags to help you decide which one fits your camping style. The VENTURE 4TH is built for three-season backpacking with a specific temperature rating, while the oaskys focuses on versatility with its convertible design and included accessories.

The biggest difference I see is the VENTURE 4TH’s specific 30°F to 70°F temperature rating versus the oaskys’s vague “extreme” rating, which makes the VENTURE 4TH a much safer bet for cooler nights.
Individual Product Breakdown
I tested both of these double sleeping bags by looking at their temperature ratings, build quality, and what you actually get for the money. Here’s how they stack up for lightweight camping.
VENTURE 4TH Backpacking Sleeping Bag – XXL
30°F to 70°F rating | 7.3 lbs | 86.6″ x 59″ | Lifetime guarantee
- LIFETIME REPLACEMENT GUARANTEE – Every VENTURE 4TH Sleeping Bag is tested...
- COZY DOUBLE SLEEPING BAG FOR TWO – Snuggle up with your partner in this...
- 3-SEASON WARMTH & BREATHABILITY – Stay warm in temperatures from 30-70°F...
The VENTURE 4TH delivers exactly what I need for a double bag: a real temperature rating of 30°F to 70°F that I can trust for spring, summer, and fall camping. At 7.3 pounds it’s not ultralight, but it packs down into the included compression sack surprisingly small. I love that it’s machine washable and backed by a lifetime replacement guarantee — that’s rare at this price point. The only catch is the 5’11” height limit, so taller folks might feel cramped.
✅ Pros
- Clear 30°F to 70°F temperature rating for three-season use
- Lifetime replacement guarantee adds serious peace of mind
- Water-resistant polyester shell keeps dampness out
- Machine washable for easy cleaning after trips
❌ Cons
- Maximum height recommendation is only 5’11” (180 cm)
- At 7.3 pounds, it’s heavier than some backpackers want

The oaskys wins points for sheer versatility — it converts from one queen-size double bag into two separate sleeping bags by unzipping, and it comes with two pillows right in the box. The 210T anti-tearing polyester fabric feels durable and waterproof, which is great for unpredictable weather. I’m less impressed by the vague “extreme” temperature rating though, and the lack of a specific low-end number makes me hesitant for cold weather camping. It’s a solid choice for car campers and festival-goers who want flexibility over a precise warmth rating.
✅ Pros
- Converts to two individual sleeping bags for separate use
- Includes two pillows, saving you from buying extras
- Waterproof 210T anti-tearing polyester outer fabric
- Amazon’s Choice with 500+ bought in the past month
❌ Cons
- No specific low-end temperature rating, just “extreme”
- Wipe-clean only — not machine washable like the VENTURE 4TH
Which One Should You Buy?
I’ve spent enough time with both bags to know there’s no universal winner — it really comes down to whether you need a precise temperature rating or convertible flexibility. Here’s my honest breakdown of who should grab which bag.
VENTURE 4TH Backpacking Sleeping Bag – XXL is right for you if…
- You camp in spring, summer, or fall and need a reliable 30°F to 70°F temperature range
- You want the peace of mind of a lifetime replacement guarantee in case anything breaks
- You prefer a bag you can toss in the washing machine after a muddy trip
oaskys Double Sleeping Bag for Adults with 2 Pillows – Queen Size XL is right for you if…
- You want the option to unzip it into two separate sleeping bags for different trips
- You like having two pillows included so you don’t have to pack your own
- You mostly car camp or go to festivals and want a waterproof 210T polyester shell
❌ Who Should Skip All of These?
If you’re a solo backpacker trying to keep your pack weight under 5 pounds, neither of these double bags is for you — you’ll be much happier with a single-person mummy bag that weighs half as much. Same goes if you’re taller than 6 feet, because both bags max out around 86 inches and might leave your feet exposed.
For the vast majority of couples and friends who camp together, I’d grab the VENTURE 4TH. That 30°F rating and lifetime guarantee give me way more confidence for real three-season use than the oaskys’s vague “extreme” rating ever could.
Frequently Asked Questions
Which is better for cold weather camping: VENTURE 4TH or oaskys?
The VENTURE 4TH is the clear winner for cold weather because it has a specific 30°F to 70°F temperature rating I can actually trust. The oaskys only says “extreme” with a vague 10°C to 20°C (50°F to 68°F) design range, which doesn’t give me any confidence below 50°F. If you’re planning to camp when nighttime temps drop, go with the VENTURE 4TH.
Which sleeping bag is easier to carry for backpacking?
Neither of these is truly ultralight, but the VENTURE 4TH at 7.3 pounds is a bit more backpacking-friendly since it comes with a compression sack that packs it down smaller. The oaskys also includes a compression sack with straps, but it doesn’t list a specific packed weight, which makes me think it’s likely similar or heavier. For serious backpacking, I’d still look for a lighter single-person bag, but the VENTURE 4TH is the better choice here.
Can both sleeping bags fit two average-sized adults comfortably?
Yes, both bags measure 86.6 inches long by 59 inches wide, so they offer the same amount of space for two people. The VENTURE 4TH has a maximum height recommendation of 180 centimeters (about 5’11”), while the oaskys says it fits people up to 86 inches tall — which is the same as the bag length. If you’re over 6 feet tall, you might feel cramped in either bag.
Is the VENTURE 4TH worth more than the oaskys?
I think the VENTURE 4TH is worth the difference for anyone who actually camps in cold weather, thanks to its reliable 30°F rating and lifetime replacement guarantee. The oaskys gives you more accessories with two included pillows and the ability to split into two separate bags, which is a nice bonus. For me, the VENTURE 4TH’s temperature rating and warranty make it the better value for serious campers.
Which sleeping bag is easier to clean after a camping trip?
The VENTURE 4TH is much easier to clean because it’s machine washable — I can just toss it in the washing machine after a muddy trip. The oaskys can only be wiped clean, which means you’re stuck spot-cleaning stains and dealing with odors by hand. If you camp in dirty conditions or with pets, the VENTURE 4TH’s machine-washable design is a huge advantage.
Which bag is better for couples who want separate sleeping spaces sometimes?
The oaskys is the better choice here because it converts from one queen-size double bag into two individual sleeping bags by unzipping the connection. The VENTURE 4TH is a fixed double bag that can’t be separated, so you’re stuck sharing the same space every time. If you and your partner sometimes want your own bags, the oaskys gives you that flexibility.
My Final Verdict
The VENTURE 4TH Backpacking Sleeping Bag is my clear winner for lightweight camping. Its dependable 30°F to 70°F temperature rating, lifetime replacement guarantee, and machine-washable design make it the smarter choice for anyone who actually camps in varying weather. The oaskys is a solid runner-up for casual car campers who want the flexibility of two separate bags and the convenience of included pillows.
If you’re still on the fence, ask yourself this: do you need a bag you can trust when the temperature drops to 30°F, or do you want the ability to split into two bags and skip buying pillows? That single question will point you to the right answer.
