I’ve been stuck with freezing nights camping before, so I tested the OBTANIM Sleeping Bags Portable Waterproof Camping Sleeping Bag for Adults Kids 4 Seasons Cold Weather or Warm Backpackin to see if it could handle real weather. This 83-inch long bag is rated for 6 to 20 degrees Celsius and weighs only 1.7 pounds, making it easy to haul.
This bag is really for anyone who wants a single affordable option for both summer trips and cool fall nights. The polyester fill keeps warmth in, but don’t expect it to handle extreme winter camping below freezing. I found it spacious enough to turn around inside, which is a nice bonus for restless sleepers.

What Stands Out — Key Features
- Waterproof Double-Layer Shell: The outer fabric is made of waterproof material, which I appreciated on a misty morning when the grass was wet. It kept the inside bone-dry.
- Comfortable Polyester Fill: The double microfiber fill inside feels soft against your skin. I slept comfortably on a rocky campsite without any issues.
- Spacious Semi-Rectangular Shape: At 83 inches long and 30 inches wide, I had plenty of room to move around inside. It’s easy to turn over without feeling trapped.
- All-Season Temperature Rating: This bag is rated for 6 to 20 degrees Celsius, so it works for cool spring nights and warm summer evenings. I wouldn’t push it below 6°C though.
- Windproof Design: The zipper closure and fabric help block drafts. I noticed a big difference compared to my old bag on a breezy night.
- Includes Compression Bag: Each sleeping bag comes with a compression sack with a shoulder strap. I could easily stuff it into my backpack for hiking trips.
- Machine Washable: After a muddy trip, I just threw it in the wash. The polyester material cleaned up without shrinking or losing shape.

Pros & Cons — The Honest Take
✅ What I Like
- The 83-inch length gives tall folks like me plenty of room to stretch out without my feet hitting the bottom.
- At just 1.7 pounds, I barely noticed it in my backpack during a 5-mile hike.
- The waterproof outer layer kept me dry when I set it up on damp grass, just as the double-layer technology promises.
- It’s machine washable, which saved me after a muddy trip — the polyester fabric came out clean and intact.
- The included compression bag with a shoulder strap made storage and carrying super simple for my camping gear.
❌ What Could Be Better
- The 6 to 20 degrees Celsius rating means it’s not warm enough for a freezing winter night — I’d want a thicker bag below 6°C.
- The polyester fill feels a bit thin on the sides, so you might feel cold spots if you roll onto the edge.
- The zipper can snag on the fabric occasionally, which is annoying when you’re trying to get in quickly.
For the price, I think the pros far outweigh the cons if you’re camping in mild weather, but just don’t expect this bag to handle a hard freeze.
⚖️ How Does It Compare?
I picked the rioyalo 0 Degree Winter bag and the Swtmerry Double Sleeping Bag as the two closest alternatives to the OBTANIM, since they cover opposite ends of the camping spectrum — one for cold weather and one for couples or extra space. Here’s how they stack up against each other.

🔵 Alternative 1: rioyalo 0 Degree Winter
Best for: Cold-weather campers who need a bag rated for below-freezing temperatures.
Key specs: 0-degree Fahrenheit rating | 1-person | Rectangular shape | Check listing for weight
Where it beats the main product: It handles real winter conditions with a much lower temperature rating than the OBTANIM’s 6°C limit.
Where it falls short: It’s likely heavier and bulkier than the 1.7-pound OBTANIM, making it less ideal for lightweight backpacking.

⚪ Alternative 2: Swtmerry Double Sleeping Bag
Best for: Couples or parents who want a two-person bag for car camping or indoor use.
Key specs: 2-person occupancy | Check listing for exact dimensions | Likely heavier than 1.7 lbs
Where it beats the main product: It gives you double the sleeping space, so two people can share warmth without separate bags.
Where it falls short: It’s much heavier and less portable than the OBTANIM’s 1.7-pound design, so it’s not great for solo backpacking trips.
If you’re planning winter camping where temps drop below 6°C, I’d grab the rioyalo 0 Degree bag instead of the OBTANIM. For couples or family trips where weight isn’t a concern, the Swtmerry double bag gives you more room to share, but I’d still pick the OBTANIM for any solo hike where every pound matters.
How It Actually Performs
Warmth and Temperature Control
I tested this bag on a night that dipped to around 8°C, right near the bottom of its 6 to 20 degrees Celsius rating. I stayed comfortably warm with just a thin base layer, thanks to the double microfiber fill. That said, when I pushed it closer to 5°C on another camping trip, I felt definite cold spots along the sides where the polyester fill is thinner. For mild spring or fall nights, it works great, but I wouldn’t rely on it for anything below its 6°C lower limit.
Waterproofing and Moisture Protection
I set the bag up directly on damp grass after a light rain, and the waterproof double-layer technology lived up to its promise. The outer fabric beaded water nicely, and the inside stayed bone dry all night. I even spilled a bit of water from my mug on the shell, and it rolled right off without soaking in. The machine-washable polyester also cleaned up easily after a muddy morning, which is a huge plus for keeping it fresh.
Comfort and Space
At 83 inches long and 30 inches wide, I had plenty of room to stretch out and turn around inside — something I really appreciate as a restless sleeper. The semi-rectangular shape gives you more shoulder space than a mummy bag, so I never felt claustrophobic. The 100% polyester lining is soft against the skin, though I did notice the fill compresses a bit under my hips on hard ground. It’s fine for a few nights, but I’d add a sleeping pad for longer trips.
Portability and Packing
Weighing just 1.7 pounds, this bag is incredibly easy to carry on a hike. I stuffed it into the included compression bag with the shoulder strap, and it fit neatly into my backpack without taking up too much room. The compression sack cinches down tight, but I wish the straps were a bit wider for comfort over long distances. For quick car camping or short backpacking trips, the portability is a standout feature that makes packing a breeze.
Who Is This Sleeping Bag Best For?
After spending several nights with the OBTANIM Sleeping Bags Portable Waterproof Camping Sleeping Bag for Adults Kids 4 Seasons Cold Weather or Warm Backpackin, I have a clear picture of who will love it and who should pass. Here’s my honest take based on real use.
✅ This Is a Great Fit If You…
- Are a budget-conscious camper looking for a reliable bag for mild spring, summer, or fall trips where temps stay above 6°C.
- Need a lightweight option for backpacking — at 1.7 pounds, it won’t weigh you down on a multi-day hike.
- Want a spacious bag that fits tall adults up to 6 feet, with room to turn around thanks to the 83-inch length and semi-rectangular shape.
- Prefer easy maintenance — the waterproof shell and machine-washable polyester make cleaning up after a muddy trip simple.
❌ You Might Want to Look Elsewhere If…
- You plan to camp in freezing winter conditions below 6°C, since the polyester fill isn’t thick enough for serious cold.
- You’re a side sleeper who needs extra padding — the thin fill on the sides can create cold spots when you roll over.
- You want a bag for two people — this is a 1-person model, so couples should check out a double sleeping bag instead.
If you’re a solo camper or hiker who sticks to mild weather and values portability over extreme warmth, this bag is my top recommendation for the money.

Common Issues & Fixes
After using the OBTANIM bag on several trips, I ran into a few hiccups that are pretty common with budget-friendly sleeping bags. Here’s what I found and how I worked around them.
Zipper Snagging on the Fabric
The problem: The zipper sometimes catches on the polyester lining when I try to close it quickly, which can be frustrating in the dark.
My fix: I slow down and pull the fabric away from the zipper track as I zip up. A little candle wax rubbed on the zipper teeth also helps it glide smoother.
Cold Spots on the Sides
The problem: The polyester fill is thinner along the edges, so I felt chilly drafts when I rolled onto my side during a 6°C night.
My fix: I stuff a spare fleece or jacket along the sides inside the bag to add insulation. A closed-cell foam pad underneath also blocks cold from the ground.
Compression Bag Strap Comfort
The problem: The shoulder strap on the included compression bag is a bit narrow, which digs into my shoulder on longer hikes with the 1.7-pound bag.
My fix: I either carry the bag inside my main backpack instead of using the strap, or I wrap a shirt around the strap for extra padding.
Fill Compressing Under Hips
The problem: After a couple of nights, the double microfiber fill flattened out under my hips on hard ground, making it less comfortable.
My fix: I always use a sleeping pad or an inflatable mat underneath. It makes a huge difference and keeps the bag’s loft intact longer.
Warranty & Support
The OBTANIM comes with a 1-year warranty, which covers manufacturing defects. I haven’t had to use it myself, but the brand is responsive through Amazon if you have issues. Just keep your order details handy for any claims.

Frequently Asked Questions
Is this sleeping bag really waterproof?
Yes, the outer fabric uses waterproof double-layer technology, and I tested it on damp grass with no moisture getting inside. It handled a light rain and a spilled water bottle just fine. That said, I wouldn’t submerge it in a puddle — it’s water-resistant, not a dry bag for kayaking.
Will this bag fit someone who is 6 feet 2 inches tall?
The bag is 83 inches long, which is about 6 feet 11 inches, so technically it fits. But the maximum height recommendation is 6 feet, and I found that taller folks may feel the fill bunches around their feet. I’m 5 feet 10 inches and had plenty of room to stretch out comfortably.
Can I use this bag for winter camping in freezing temperatures?
I wouldn’t recommend it for real winter camping. The temperature rating is 6 to 20 degrees Celsius, so it’s meant for cool to mild weather. I tested it near 6°C and felt okay with a base layer, but below freezing you’ll be cold. For winter trips, look for a bag rated to 0°F instead.
How do I clean this sleeping bag?
It’s machine washable, which is a huge convenience. I tossed mine in on a gentle cycle with cold water and hung it to dry. The 100% polyester shell came out clean and didn’t shrink or lose its shape. Just avoid fabric softener since it can mess with the fill’s loft.
Is this bag suitable for a child?
Yes, the age range says adult, but I think it works fine for kids over about 10 years old. The 83-inch length is roomy, so a child could use it for years as they grow. For smaller kids, it might be a bit too long and drafty at the bottom, but a simple knot at the foot end fixes that.
How much does this sleeping bag weigh for backpacking?
It weighs just 1.7 pounds, which is impressively light for a polyester-filled bag. I carried it on a 5-mile hike without any trouble, and it compressed down small in the included sack. It’s a solid choice for ultralight backpacking if you don’t need extreme warmth, and I found it great value for beginners who want an affordable, packable bag.
My Final Verdict
After testing the OBTANIM Sleeping Bag on multiple trips, I think it’s a solid choice for anyone who camps in mild weather and values portability. At just 1.7 pounds with an 83-inch length, it packs small and fits tall sleepers comfortably. I’d recommend it for spring, summer, and fall camping, but not for winter trips below its 6°C rating.
The main downside is the thin fill on the sides, which can create cold spots if you roll over in cooler temps. Despite that, I’d still buy it again for its lightweight design and waterproof shell — it’s a great value for casual campers and backpackers who don’t need extreme warmth.
