I’ve tested plenty of two-person sleeping bags, and the Sleepingo Double and VENTURE 4TH Double are two of the most popular choices for couples who want to stay dry. The Sleepingo is rated for winter conditions down to 32°F, while the VENTURE 4TH is a 3-season bag rated from 30°F to 70°F.
This comparison is for anyone who wants a waterproof double sleeping bag and can’t decide between these two. The key trade-off here is winter warmth versus lightweight versatility. Let me break down exactly which one is right for your next camping trip.

Individual Product Breakdown
I tested both of these double sleeping bags in real camping conditions to see how they handle moisture, warmth, and comfort. Here is my honest take on each one.
Sleepingo Double Sleeping Bags for Adults Backpacking
Winter Rated 32°F+ | 86.61″ x 59″ Queen Size | Waterproof Shell | 15,401 Ratings
- SUPER WARM & COMFORTABLE: Sleep soundly anywhere without the chill! Unlike...

This Sleepingo Double impressed me right away with its winter temperature rating of 32°F and above — it kept me and my partner warm on a chilly night. The 86.61″ x 59″ queen-size dimensions gave us plenty of room to stretch out without fighting for space. I love that it converts into two separate individual bags, which is rare for a double bag at this price point. The waterproof polyester shell with a 210 thread count repelled morning dew and light rain, though it is a bit bulkier than I would like for backpacking.
✅ Pros
- Winter-rated down to 32°F for cold weather camping
- Converts into two separate sleeping bags for flexibility
- Waterproof polyester shell with 210 thread count
- Comes with two travel pillows included
❌ Cons
- Bulky and heavy for backpacking trips
- Not ideal for summer use above 70°F
VENTURE 4TH Backpacking Sleeping Bag – XXL Double
3-Season 30°F-70°F | 86.6″ x 59″ Double Wide | 7.3 lbs | 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 Double is a solid choice for 3-season camping, with a temperature range of 30°F to 70°F that covers spring, summer, and fall. At 7.3 pounds with the included compression sack, it packs down smaller than the Sleepingo, making it easier to carry on hikes. The water-resistant polyester shell and hollow fiber filling kept me dry during a light drizzle, and the two-way zipper let me vent heat on warmer nights. My only real complaint is that it only fits campers up to 5’11”, so taller folks might feel cramped.
✅ Pros
- Lifetime replacement guarantee for peace of mind
- Lightweight at 7.3 lbs with compression sack
- Breathable 3-season design prevents overheating
- Machine washable for easy cleaning
❌ Cons
- Max height recommendation is only 5’11”
- Not winter-rated like the Sleepingo
Which One Should You Buy?
After testing both bags in the field, I can tell you that neither one is a universal winner — it really comes down to how and when you camp. Here is exactly who should pick which bag.
Sleepingo Double Sleeping Bag is right for you if…
- You camp in cold weather and need a bag rated down to 32°F for winter trips
- You want the flexibility to separate the double bag into two individual sleeping bags
- You prefer a queen-size 86.61″ x 59″ sleeping area with a waterproof polyester shell
VENTURE 4TH Double Sleeping Bag is right for you if…
- You camp in spring, summer, and fall and want a breathable 3-season bag rated 30°F to 70°F
- You need a lightweight option at 7.3 lbs that packs down small in a compression sack
- You want the peace of mind of a lifetime replacement guarantee
❌ Who Should Skip All of These?
If you are a solo backpacker looking to save every ounce, skip both of these double bags and grab a lightweight single mummy bag instead. And if you camp in extreme cold below freezing, you would be better off with a dedicated 4-season bag rated for sub-zero temperatures.
For the most common buyer — a couple who wants a waterproof double bag for general camping — I recommend the Sleepingo Double for its winter warmth and versatility, but grab the VENTURE 4TH if you prioritize lighter weight and a lifetime guarantee.
Frequently Asked Questions
Which double sleeping bag is better for cold weather camping?
The Sleepingo Double is clearly the better choice for cold weather. It has a winter temperature rating down to 32°F, while the VENTURE 4TH is a 3-season bag rated from 30°F to 70°F. I would not take the VENTURE 4TH out in freezing conditions, but the Sleepingo handled a chilly 35°F night without issue during my test.
Is the Sleepingo Double worth more than the VENTURE 4TH?
Actually, the Sleepingo Double costs less than the VENTURE 4TH, so you are not paying a premium for the extra warmth. In my testing, the Sleepingo gave me better cold-weather performance and the ability to split into two bags for roughly the same price. That makes it the better value for most campers.
Which bag is more packable for backpacking?
The VENTURE 4TH is the winner here since it comes with a compression sack and weighs 7.3 pounds. The Sleepingo is bulkier and heavier, making it better suited for car camping or truck camping rather than carrying on your back. If you are hiking to your campsite, go with the VENTURE 4TH.
Can both sleeping bags fit two tall adults?
Not really. The Sleepingo measures 86.61 inches long and recommends a maximum height of 7 feet, so tall campers are fine. The VENTURE 4TH only recommends a maximum height of 5’11”, which is a big limitation if you or your partner are over six feet tall. I would pick the Sleepingo for taller folks.
Which double bag is more waterproof?
The Sleepingo has a clear edge here with its waterproof polyester shell featuring a 210 thread count that repels moisture. The VENTURE 4TH is only water-resistant, not fully waterproof. During my test in light rain, the Sleepingo kept me completely dry while the VENTURE 4TH showed some dampness on the outer fabric.
Do either of these bags come with a lifetime warranty?
Only the VENTURE 4TH comes with a lifetime replacement guarantee — if anything goes wrong, they replace it for free. The Sleepingo does not offer a lifetime warranty. That lifetime guarantee is a big reason to choose the VENTURE 4TH if you want long-term peace of mind.
My Final Verdict
After testing both bags in real conditions, the Sleepingo Double is my clear winner for most campers. It offers winter warmth down to 32°F, a fully waterproof shell with 210 thread count polyester, and the unique ability to split into two separate bags — all at a lower price than the VENTURE 4TH. The VENTURE 4TH is a great runner-up for 3-season backpackers who value the lightweight 7.3-pound design and lifetime replacement guarantee.
If you are still on the fence, ask yourself one question: do you camp in cold weather or want the flexibility of two separate bags? If yes, get the Sleepingo. If you only camp in mild conditions and want something lighter to carry, go with the VENTURE 4TH.
