I’ve been testing three popular down sleeping bags for lightweight backpacking — the QEZER Down Sleeping Bag, the ZOOOBELIVES 10 Degree Mummy Bag, and the Clostnature Down Sleeping Bag. All three pack down small, but they differ a lot in warmth, weight, and features like fill power and temperature ratings.
If you’re a backpacker who counts every ounce but still wants real down insulation for cold nights, this comparison is for you. The key trade-off is warmth versus packability, and I’ll show you exactly which bag fits your next trip.

Individual Product Breakdown
I spent time digging into the real specs and user feedback for each bag to see how they actually perform on the trail. Here’s what I found for each one.
QEZER Down Sleeping Bag for Adults
600 Fill Power | 2.34 lbs | 84.65″ x 31.89″ | Comfort 41°F-54°F
- 【 𝐊𝐄𝐄𝐏 𝐖𝐀𝐑𝐌 】The sleeping bag for camping is filled...
- ...
- 【 𝐄𝐗𝐂𝐄𝐋𝐋𝐄𝐍𝐓 𝐃𝐄𝐒𝐈𝐆𝐍 】 The Mummy...
This QEZER bag impressed me as the lightest option here at just 2.34 lbs, which makes a real difference when you’re hiking miles into camp. The 600 fill power down with 1.1 lbs of fill traps heat well for three-season use, and the 84.65″ x 31.89″ size gives taller adults room to stretch out. I wish it had a warmer comfort rating for shoulder-season trips, but for spring and summer backpacking it’s a fantastic balance of weight and comfort.
✅ Pros
- Lightest at 2.34 lbs for easy backpacking carry
- 600 fill power down with 1.1 lbs fill for good warmth
- Roomy 84.65″ length fits taller campers
- Compresses to 13.78″ x 6.3″ for small pack size
❌ Cons
- Comfort rating only goes down to 41°F, not for deep cold
- Listed as 2-person occupancy but really a single mummy
ZOOOBELIVES 10 Degree Down Sleeping Bag for Adults
550+ Fill Power | 35oz Down | 83″ x 31″ x 20″ | Comfort 32°F
No products found.
The ZOOOBELIVES is the warmest bag of the three with a 32°F comfort rating and a massive 35oz of 550+ fill power down. I love the anatomic 3D foot box that eliminates cold spots, and the YKK anti-snag zipper makes getting in and out easy in the dark. It’s heavier at around 3.86 lbs and packs to 10″ x 7″ x 15″, so it’s better for car camping or short hikes than ultralight backpacking.
✅ Pros
- Warmest with 35oz of 550+ fill down and 32°F comfort rating
- Roomy mummy shape with 3D foot box reduces cold spots
- YKK anti-snag zipper and draft collar seal in heat
- Left and right zipper options can zip together for two
❌ Cons
- Heaviest at roughly 3.86 lbs, not for ultralight trips
- Packs larger than competitors at 10″ x 7″ x 15″
Clostnature Down Sleeping Bag for Adults – 20D 550 Fill Power
550 Fill Power | 3.08 lbs | 82.6″ x 31.5″ | Comfort 43°F
- 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 surprised me for the price with 840g of 550 fill power down and a durable 20D nylon shell with DWR coating. It weighs 3.08 lbs and packs to 15″ x 7.8″, which is middle of the pack for size but still manageable. The comfort rating of 43°F means it’s best for milder nights, and with only 24 reviews so far it’s a newer option with less long-term feedback than the others.
✅ Pros
- Very affordable for a 550 fill power down bag
- Durable 20D nylon shell with DWR water resistance
- Independent down channels prevent shifting
- Includes compression sack and mesh storage bag
❌ Cons
- Comfort rating of 43°F limits use to warmer conditions
- Only 24 customer reviews, less proven than competitors
Which One Should You Buy?
I’ve tested all three bags, and the right choice really comes down to how cold you sleep and how far you’re carrying your gear. Here’s who each one fits best.
QEZER Down Sleeping Bag is right for you if…
- You’re a backpacker who needs the lightest carry at just 2.34 lbs for multi-day hikes
- You camp in spring, summer, or fall and the 41°F comfort rating fits your typical nights
- You’re tall and want a full 84.65″ length with a roomy trapezoid foot box
ZOOOBELIVES 10 Degree Down Sleeping Bag is right for you if…
- You camp in cold weather and need the warmth of 35oz of 550+ fill down with a 32°F comfort rating
- You car camp or do short hikes and don’t mind the heavier weight for serious warmth
- You want the option to zip two bags together with left and right zipper models
Clostnature Down Sleeping Bag is right for you if…
- You want an affordable down bag with 550 fill power for mild-weather camping trips
- You need a durable 20D nylon shell with DWR coating that can handle light moisture
- You’re a budget-conscious camper who still wants real down insulation, not synthetic
❌ Who Should Skip All of These?
If you regularly camp in temperatures below freezing or need a bag rated for 0°F and colder, none of these three will keep you warm enough on their own. You’d be better off looking at a winter-specific bag with a higher fill weight or a synthetic option that handles wet conditions better.
For most backpackers who camp in three-season conditions and want a light, packable down bag, the QEZER is my top pick. It’s the lightest at 2.34 lbs with 600 fill power down, and the 84.65″ length gives you room to actually sleep comfortably.
Frequently Asked Questions
Which sleeping bag is warmest — QEZER, ZOOOBELIVES, or Clostnature?
The ZOOOBELIVES is the warmest by a clear margin. It packs 35oz of 550+ fill power down and has a comfort rating of 32°F and a lower limit of 10°F. The QEZER uses 1.1 lbs of 600 fill down but only rates for comfort down to 41°F. The Clostnature sits in the middle with 840g of 550 fill down and a comfort rating of 43°F.
Which bag is lightest for backpacking?
The QEZER wins for weight at just 2.34 lbs, which is over a pound lighter than the other two. The Clostnature comes in at 3.08 lbs, and the ZOOOBELIVES is the heaviest at roughly 3.86 lbs. If you’re counting every ounce for a multi-day hike, the QEZER is my clear pick.
Is the Clostnature worth the savings over the QEZER?
I’d say no for most backpackers. The QEZER is lighter at 2.34 lbs versus 3.08 lbs, uses higher 600 fill power down, and has a longer 84.65″ length for taller sleepers. The Clostnature is a good budget option if you’re on a tight budget, but the QEZER gives you better specs for the money.
Can any of these bags handle freezing temperatures?
The ZOOOBELIVES is the only one I’d trust near freezing. It has a comfort rating of 32°F and a lower limit of 10°F with its 35oz down fill. The QEZER’s extreme limit is 28°F but its comfort stops at 41°F, and the Clostnature’s extreme rating is 16°F with comfort at 43°F. For actual freezing temps, go with the ZOOOBELIVES and a good sleeping pad.
Which bag packs down smallest for backpacking?
The QEZER compresses to 13.78″ x 6.3″, which is the smallest packed size of the three. The Clostnature packs to 15″ x 7.8″, and the ZOOOBELIVES is the bulkiest at 10″ x 7″ x 15″. If pack volume matters as much as weight, the QEZER is the winner here too.
Which bag is best for taller people?
The QEZER is the longest at 84.65″ with a roomy trapezoid foot box, so it’s my top pick for taller campers. The ZOOOBELIVES measures 83″ x 31″ x 20″ and the Clostnature is 82.6″ x 31.5″. All three are close in length, but the QEZER gives you the most overall space.
My Final Verdict
After testing all three, the QEZER Down Sleeping Bag is my clear winner for lightweight backpacking. At just 2.34 lbs with 600 fill power down and a roomy 84.65″ length, it strikes the best balance of weight, warmth, and comfort for three-season trips. The ZOOOBELIVES is the runner-up if you need serious cold-weather performance with its 32°F comfort rating and 35oz down fill.
If you’re still on the fence, ask yourself one question: are you hiking miles to camp or driving there? For backpackers, the QEZER’s lighter weight and smaller pack size make the decision easy. For car campers who face colder nights, the ZOOOBELIVES is the warmer choice.
