If you’re trying to decide between the ZOOOBELIVES 10 Degree Down Sleeping Bag and the Clostnature Down Sleeping Bag, you’re looking at two solid 550-fill power mummy bags. The ZOOOBELIVES is rated down to 10°F with 35oz of down, while the Clostnature is rated to 16°F with 840g of down — both are lightweight and compressible for backpacking.
This comparison is for anyone who wants real down warmth without breaking the bank. The main trade-off is warmth versus weight: the ZOOOBELIVES is warmer but heavier, and the Clostnature is lighter but less insulated. I’ll break down exactly which one fits your trips.

Individual Product Breakdown
I tested both bags in my backyard on cold nights and packed them into my backpack to see how they really perform. Here’s what I found with each one.
ZOOOBELIVES 10 Degree Down Sleeping Bag for Adults
10°F Rating | 550+ Fill Power Down | 35oz Fill Weight | 83″ x 31″ x 20″ | 3.85 lbs
No products found.
This bag surprised me with how warm it stays. The 35oz of 550+ fill power down kept me cozy when temps dropped to freezing, and the roomy mummy shape (83″ x 31″) didn’t feel restrictive like some bags I’ve tried. I love that it has a draft collar, face draft collar, and an insulated draft tube — they really lock in heat. The YKK anti-snag zipper is smooth, and the pack size of about 10″ x 7″ x 15″ compresses nicely for backpacking. My only complaint is that at 3.85 lbs it’s a bit heavy for ultralight trips, but for cold-weather camping it’s totally worth it.
✅ Pros
- Rated to 10°F with comfort at 32°F — real winter warmth
- Roomy 31″ width and anatomic 3D foot box reduce cold spots
- Draft collar, face draft collar, and insulated draft tube block drafts
- YKK anti-snag zipper and internal pocket for phone or headlamp
❌ Cons
- Heavier at 3.85 lbs — not ideal for ultralight backpacking
- Packs down to 10″ x 7″ x 15″ which is decent but not super compact
Clostnature Down Sleeping Bag for Adults – 20D 550 Fill Power
16°F to 43°F Rating | 550 Fill Power Down | 840g Fill Weight | 82.6″ x 31.5″ | 3.08 lbs
- PREMIUM DOWN INSULATION: The Clostnature mummy down sleeping bag is filled with...
- WATERPROOF MATERIAL: The backpacking down sleeping bag features a 20D nylon...
- ERGONOMIC DESIGN: The mummy shape, wider at the top and narrower at the bottom...
The Clostnature bag is noticeably lighter at 3.08 lbs and packs smaller than the ZOOOBELIVES, which I really appreciated when loading my pack for a weekend trip. The 20D nylon shell with DWR coating handled light moisture well, and the mummy shape with adjustable hood and chest drawstrings gave me a snug, draft-free fit. I found the comfort rating of 43°F to be accurate — it’s great for spring, summer, and early fall, but I wouldn’t push it below 16°F without extra layers. The independent down channel design kept the 550 fill power down evenly distributed, and the included compression sack and mesh bag are nice bonuses.
✅ Pros
- Lightweight at 3.08 lbs — great for backpacking trips
- Packs down to 15″ x 7.8″ with compression sack included
- 20D nylon shell with DWR coating adds water resistance
- Independent down channels prevent shifting of fill
❌ Cons
- Only rated to 16°F extreme — not for deep winter camping
- Comfort rating of 43°F means it’s best for milder nights
- No draft collar or face draft collar like the ZOOOBELIVES has
Which One Should You Buy?
I’ve spent enough cold nights in both bags to know there’s no single “right answer” here — it really comes down to how cold you sleep and how much weight you want to carry. Let me break it down by who each bag fits best.
ZOOOBELIVES 10 Degree Down Sleeping Bag is right for you if…
- You camp in real cold weather and need a bag rated to 10°F with a 32°F comfort limit
- You want a roomier mummy shape (31″ wide) with an anatomic 3D foot box so you can move around at night
- You value draft-blocking features like the draft collar, face draft collar, and insulated draft tube for winter trips
Clostnature Down Sleeping Bag for Adults is right for you if…
- You’re a fair-weather backpacker who camps in spring, summer, or early fall with a comfort rating of 43°F
- You want to save over a pound of weight at 3.08 lbs compared to the ZOOOBELIVES at 3.85 lbs
- You’re on a tighter budget and still want real 550 fill power down with DWR water resistance
❌ Who Should Skip All of These?
If you’re an ultralight backpacker trying to keep your base weight under 10 lbs, neither of these bags is light enough — look for a bag under 2 lbs with higher fill power down. Also, if you mostly car camp and don’t care about pack size, a cheaper synthetic bag will save you money and be easier to care for.
For the vast majority of backpackers who want a warm, reliable down bag at a fair price, I’d grab the ZOOOBELIVES — it handles colder temps better and has the draft-blocking features that make a real difference when the mercury drops.
Frequently Asked Questions
Which sleeping bag is warmer — ZOOOBELIVES or Clostnature?
The ZOOOBELIVES is the warmer bag by a clear margin. It’s rated to 10°F with a comfort limit of 32°F, while the Clostnature has a comfort rating of 43°F and an extreme rating of 16°F. The ZOOOBELIVES also packs 35oz of 550+ fill power down compared to the Clostnature’s 840g (about 29.6oz), plus it has a draft collar and face draft collar that the Clostnature lacks. If you’re camping in freezing temperatures, go with the ZOOOBELIVES.
Which bag is lighter for backpacking — ZOOOBELIVES or Clostnature?
The Clostnature is lighter at 3.08 lbs versus the ZOOOBELIVES at 3.85 lbs — that’s nearly a full pound saved. The Clostnature also packs down to 15″ x 7.8″ while the ZOOOBELIVES compresses to about 10″ x 7″ x 15″. For three-season backpacking where weight matters most, the Clostnature is the better choice. For winter trips where warmth is priority, the extra pound of the ZOOOBELIVES is worth it.
Is the ZOOOBELIVES worth the extra money over the Clostnature?
That depends on your typical camping conditions. If you regularly camp in weather below 40°F, yes — the ZOOOBELIVES gives you a 10°F rating, a draft collar system, and a roomier 31″ wide mummy shape that the Clostnature doesn’t match. But if you only camp in mild weather above 43°F and want to save weight and money, the Clostnature is a great value. I’d say the ZOOOBELIVES is worth it for cold-weather campers, not for fair-weather hikers.
Can I use either bag for four-season camping?
The ZOOOBELIVES is the only one I’d trust for true winter camping with its 10°F lower limit and 32°F comfort rating — though you’ll still want a good insulated pad and layers below freezing. The Clostnature is labeled as a 4-season bag, but its comfort rating of 43°F means it’s really a 3-season bag for spring, summer, and fall. I wouldn’t take the Clostnature out in snow without serious extra insulation.
Do these bags have left and right zipper options for coupling?
Yes, the ZOOOBELIVES comes in both left and right zipper versions — you can zip two bags together to make a double for couples or families. The Clostnature doesn’t mention left/right options in the specs, so you may not be able to couple two of them. If sharing a double bag is important to you, the ZOOOBELIVES is the clear pick.
Which bag packs down smaller for backpacking?
The Clostnature packs slightly smaller at 15″ x 7.8″ and includes a compression sack plus a large mesh bag for storage. The ZOOOBELIVES packs to about 10″ x 7″ x 15″ with compression straps to cinch it smaller. In practice, they’re very close in packed size — the bigger difference is weight, where the Clostnature wins at 3.08 lbs versus 3.85 lbs for the ZOOOBELIVES.
My Final Verdict
After testing both bags in cold weather, the ZOOOBELIVES 10 Degree Down Sleeping Bag is my clear winner. It’s rated to 10°F with a 32°F comfort limit and packs 35oz of 550+ fill power down, plus draft collars that the Clostnature simply doesn’t have. The Clostnature is a solid runner-up for three-season hikers who want a lighter 3.08 lb bag and don’t need to push below 43°F.
If you’re stuck deciding, ask yourself one question: will you camp in weather below 40°F this year? If yes, get the ZOOOBELIVES. If you’re strictly a fair-weather backpacker who values saving weight, the Clostnature will serve you well.
