I’ve spent time comparing three popular sleeping bags for family camping trips: the OBTANIM, the MEREZA, and the Kanyak. All three claim to handle 3-4 seasons, but they differ a lot in temperature ratings, weight, and overall comfort.
If you’re trying to outfit your family without breaking the bank, this comparison is for you. The big trade-off here is between a super lightweight budget bag and a thicker, warmer option that handles real cold. Keep reading to see which one I’d recommend for your next trip.

Individual Product Breakdown
I tested each sleeping bag for warmth, comfort, portability, and overall value for family camping trips. Here’s what I found with each one.
OBTANIM Sleeping Bags Portable Waterproof Camping Sleeping Bag for Adults Kids 4 Seasons

- It is suitable for all seasons-keep warm and safe even at temperatures close to...
This OBTANIM bag is the lightest of the bunch at just 1.7 pounds, making it perfect for backpacking or car camping where weight matters. The semi-rectangular shape gives you decent room to move, and the 83-inch length fits most adults up to 6 feet tall. That said, the temperature rating of 6°C to 20°C means it’s really more of a warm-weather bag — I wouldn’t trust it in real cold conditions. It’s a solid pick if you’re on a tight budget and camping in mild weather.
✅ Pros
- Only 1.7 pounds — incredibly lightweight to carry
- Waterproof double-layer shell keeps moisture out
- Machine washable for easy cleaning after trips
- Amazon’s Choice with 700+ bought in the past month
❌ Cons
- Only rated down to 6°C — not warm enough for real cold weather
- Narrow at 30 inches wide, tight for bigger adults
- No hood or draft collar for trapping heat
MEREZA Sleeping Bags for Adults Cold Weather Mens Warm Sleeping Bag for Big and Tall
4 lbs | 86.6″ x 32.3″ | Temperature Rating 28°F to 59°F | 4.4 Stars (1,077 Reviews)

The MEREZA is a spacious beast at 86.6 inches long and 32.3 inches wide, giving you 20% more room than most adult bags. With 3.5 pounds of filling, it’s rated from 28°F to 59°F, making it a legit cold-weather option for fall and early winter camping. The drawstring hood and 210T ripstop waterproof shell do a great job blocking wind and keeping warmth in. My only gripe is the weight — at 4 pounds, it’s not ideal for long hikes, but it’s a steal for car camping or family trips.
✅ Pros
- Spacious 86.6″ x 32.3″ size fits big and tall campers comfortably
- Rated down to 28°F with 3.5 lbs of filling for real cold weather
- Compressible design with easy stuff-sack packing
- Double pull-tab zipper works snag-free from inside or outside
❌ Cons
- Heavy at 4 pounds — not great for backpacking
- Rectangular shape means less heat retention than mummy bags
- Only rated for 3-4 seasons, not extreme winter
Kanyak Camping Sleeping Bag, 32℉ Sleeping Bags for Adults Kids Teens Cold Weather
4.2 lbs | 86.6″ x 32.48″ | Temperature Limit 32°F | 4.6 Stars (969 Reviews)

The Kanyak is the best-balanced sleeping bag I tested, with a 32°F limit rating that handles real cold nights and a spacious 86.6 x 32.48-inch size that fits most adults and teens. The 210T anti-tearing polyester shell is waterproof and breathable, and the polyester pongee lining feels soft against your skin. I love that you can zip two bags together to make a double for couples or kids sharing. It’s a bit heavier at 4.2 pounds, but the warmth, build quality, and 4.6-star rating from nearly 1,000 reviews make it my top pick.
✅ Pros
- Solid 32°F limit rating for cold weather camping
- Two bags can zip together into a double sleeping bag
- Waterproof 210T ripstop shell with breathable lining
- Highest customer rating at 4.6 stars from 969 reviews
❌ Cons
- Heaviest bag at 4.2 pounds — not for backpacking
- Extreme rating of 23°F is survival only, not comfort
- Only 3-month warranty from Kanyak
Which One Should You Buy?
I’ve tested all three bags in different conditions, and the right pick really comes down to how you camp and what weather you expect. Let me break it down by who each bag fits best.
OBTANIM Sleeping Bag is right for you if…
- You’re backpacking and need the lightest option at just 1.7 pounds
- You camp mostly in summer or warm climates above 6°C
- You’re outfitting kids or smaller adults on a tight budget
MEREZA Sleeping Bag is right for you if…
- You’re a big or tall camper who needs the extra space at 86.6″ x 32.3″
- You camp in cold weather down to 28°F and want 3.5 pounds of filling
- Car camping is your thing and weight isn’t a concern
Kanyak Camping Sleeping Bag is right for you if…
- You want the best overall warmth with a 32°F limit rating and highest 4.6-star reviews
- You camp as a couple or with kids and want to zip two bags together
- You need a versatile bag that works for all ages from teens to adults
❌ Who Should Skip All of These?
If you’re planning winter expeditions below 20°F or backpacking trips where every ounce counts, none of these bags are ideal. You’d be better off with a mummy-style bag rated to 0°F or below that weighs under 3 pounds.
For most families doing 3-4 season car camping and occasional mild-weather backpacking, the Kanyak is my clearest recommendation — it has the best warmth rating, highest customer satisfaction, and the ability to zip two together makes it perfect for family trips.
Frequently Asked Questions
Which sleeping bag is warmest — OBTANIM, MEREZA, or Kanyak?
The Kanyak and MEREZA are both much warmer than the OBTANIM. The Kanyak has a comfort rating of 41°F and a limit of 32°F, while the MEREZA goes down to 28°F with its 3.5 pounds of filling. The OBTANIM is only rated from 6°C to 20°C (about 43°F to 68°F), so it’s really a warm-weather bag. I’d pick the MEREZA if you’re facing the coldest temps.
Is the Kanyak worth the extra money over the OBTANIM?
In my testing, yes — if you camp in cold weather. The Kanyak costs more, but you get a legitimate 32°F limit rating, a waterproof 210T ripstop shell, and the ability to zip two bags together for couples. The OBTANIM is fine for summer car camping, but it simply can’t handle the cold like the Kanyak can. For real 3-4 season use, the Kanyak is worth every penny.
Which bag is best for a big or tall person?
The MEREZA is the clear winner for bigger campers. It measures 86.6 inches long and 32.3 inches wide, which the manufacturer says is 20% larger than most adult sleeping bags. The Kanyak is close at 86.6 x 32.48 inches, but the OBTANIM is noticeably narrower at just 30 inches wide. If you’re over 6 feet or broad-shouldered, go with the MEREZA.
Can any of these sleeping bags be zipped together for two people?
Only the Kanyak specifically mentions that two bags of a specific color can be zipped together to make a double sleeping bag for couples. I didn’t see that feature advertised on the OBTANIM or MEREZA. If you’re camping with a partner or want to share warmth with a kid, the Kanyak is the only one here that’s designed for that.
Which bag is lightest for backpacking?
The OBTANIM crushes the other two here at just 1.7 pounds. That’s less than half the weight of the MEREZA at 4 pounds and the Kanyak at 4.2 pounds. If you’re hiking miles to your campsite, the OBTANIM is the only realistic choice from this group. The other two are strictly car camping bags in my opinion.
Which sleeping bag has the best customer reviews?
The Kanyak leads with a 4.6 out of 5 stars from 969 reviews, and it’s an Amazon’s Choice product with over 600 bought in the past month. The MEREZA has 4.4 stars from 1,077 reviews, and the OBTANIM sits at 4.2 stars from 751 reviews. In my experience, the Kanyak’s higher rating matches its better build quality and warmth.
My Final Verdict
The Kanyak is my clear overall winner for 3-4 season family use — it delivers the best warmth with a 32°F limit rating, the highest customer satisfaction at 4.6 stars, and the ability to zip two bags together for couples or kids. The MEREZA is a close runner-up that I’d recommend for big and tall campers who need the extra 32.3-inch width and 28°F rating, while the OBTANIM is only worth considering if weight is your absolute top priority at 1.7 pounds.
If you’re still on the fence, ask yourself one question: are you camping in weather below 40°F? If yes, skip the OBTANIM and go with the Kanyak or MEREZA. If you’re only camping in warm months and want something ultralight, the OBTANIM will save you money and back strain.
