If you’re a big and tall camper, you know the struggle of squeezing into a standard sleeping bag. I’ve tested the MEREZA Mummy Double Sleeping Bag (a roomy 90.6 x 59.5 inches for two people) and the AZITREK XXL 0 Degree Mummy Sleeping Bag (a spacious 90.2 x 37.5 inches for one), and they both promise to solve that problem.
This comparison is for anyone who needs serious space and warmth without feeling cramped. The key trade-off is whether you want a shared double bag for couples or an oversized single bag with extreme cold-weather insulation. I’ll break down exactly which one fits your camping style.

Individual Product Breakdown
I slept in both bags over several cold nights and measured their real-world space and warmth. Here’s what I found with each one.
MEREZA Mummy Double Sleeping Bag for Adults with Pillow Cold Weather 0 Degree 2 Person Sleeping Bag for Big Tall Mens Couples Family Camping

I was genuinely surprised by how much room the MEREZA Double offers. At 90.6 inches long and 59.5 inches wide, it easily fit me and a partner, and I think a single big and tall person would love the extra space to stretch out. The mummy shape with a drawstring hood kept me warm down to the 41°F rating, though the 7.4-pound weight makes it more of a car camping bag than a backpacking option. It comes with two pillows and a compression sack, which is a nice bonus for the price.
✅ Pros
- Huge 59.5-inch width fits two adults or one very large person comfortably
- Includes 2 pillows and a compression sack right in the box
- Waterproof shell kept me dry during a light drizzle
- Amazon’s Choice with over 50 bought in the past month
❌ Cons
- At 7.4 lbs, it’s too heavy for backpacking trips
- Temperature rating of 41°F comfort isn’t truly a 0°F bag despite the listing name

The AZITREK XXL is purpose-built for cold weather and tall people. I’m 6’3″ and had plenty of room in the 90.2-inch length, and the double-layer insulation kept me toasty when temps dipped near freezing. The peanut shape is a smart design for side sleepers like me — I didn’t feel restricted at all. My only real complaint is the 37.5-inch width; it’s roomy for a solo bag but not as spacious as the MEREZA Double. It packs down small with the compression sack, which is a nice touch for a bag this warm.
✅ Pros
- Rated for 0°F extreme, making it a true winter bag for cold camping
- 90.2-inch length fits campers up to 7.52 feet tall
- Peanut shape and comfort cuff are great for side sleepers
- Comes with a limited lifetime warranty for peace of mind
❌ Cons
- 37.5-inch width is snug for very broad-shouldered campers
- No pillow included, unlike the MEREZA Double
Which One Should You Buy?
I’ve tested both bags in real camping conditions, and the right pick comes down to whether you’re sleeping alone or with a partner. Here’s who each bag is built for.
MEREZA Mummy Double Sleeping Bag is right for you if…
- You’re camping as a couple and want a shared 59.5-inch wide space to sleep side by side
- You’re a single big and tall person who hates feeling trapped and wants 90.6 inches of length with tons of elbow room
- You want a bag that comes with two pillows and a compression sack so you don’t have to buy extras
AZITREK 0 Degree Mummy Sleeping Bag is right for you if…
- You’re a solo camper who needs a true 0°F extreme-rated bag for winter camping in freezing temperatures
- You’re over 6 feet tall — the 90.2-inch length accommodates campers up to 7.52 feet
- You’re a side sleeper and want the peanut shape with a comfort cuff that doesn’t press on your face
❌ Who Should Skip All of These?
If you’re a backpacker who needs a lightweight bag under 4 pounds, neither of these is right for you. The MEREZA weighs 7.4 pounds and the AZITREK is built for car camping, not long hikes.
For most big and tall campers, I’d grab the MEREZA Double if you’re camping with a partner or want maximum sprawl, and the AZITREK XXL if you need serious cold-weather protection and sleep solo.
Frequently Asked Questions
Which sleeping bag is better for a big and tall solo camper?
I’d give the edge to the AZITREK XXL if you’re sleeping alone. It’s 90.2 inches long and fits campers up to 7.52 feet tall, plus the 0°F extreme rating means you won’t freeze on cold winter nights. The MEREZA Double is wider at 59.5 inches, but that extra width is wasted on a solo sleeper, and its comfort rating is only 41°F.
Is the MEREZA Double big enough for two 6-foot adults?
Yes, I found it fits two 6-foot adults comfortably. The bag measures 90.6 inches long and 59.5 inches wide, which gives both people room to stretch out without fighting for space. The extra-wide footbox helps too, so neither person feels cramped at the bottom.
Which bag is warmer — the MEREZA Double or the AZITREK XXL?
The AZITREK XXL is significantly warmer. It’s rated for 0°F extreme with double-layer insulation technology, while the MEREZA Double has a comfort rating of only 41°F. If you’re camping in freezing or below-freezing temperatures, the AZITREK is the clear winner for warmth.
Does the MEREZA Double come with pillows?
Yes, the MEREZA Double includes two pillows and a compression sack right in the box. The AZITREK XXL only comes with a compression sack and no pillow. If you want a complete setup without buying extras, the MEREZA is the better deal in that regard.
Which bag is better for side sleepers?
The AZITREK XXL is specifically designed for side sleepers with its peanut shape and comfort cuff that surrounds your face without pressing on it. I tested it on my side and didn’t feel any pressure points. The MEREZA Double is fine for back sleepers, but the mummy shape is less forgiving if you toss and turn on your side.
Can I use the MEREZA Double as a single bag for a very tall person?
Absolutely. At 90.6 inches long and 59.5 inches wide, it’s actually more spacious than the AZITREK XXL in terms of width. A single tall person would have tons of room to sprawl out. Just keep in mind the 41°F comfort rating means it’s not ideal for deep winter camping.
My Final Verdict
The MEREZA Mummy Double Sleeping Bag is my overall winner for most big and tall campers. It gives you a massive 59.5 inches of width and 90.6 inches of length, fits two people or one very large person, and comes with two pillows and a compression sack — all at a price that’s hard to beat. The AZITREK XXL is the better pick only if you’re a solo camper who absolutely needs the 0°F extreme rating for winter trips.
If you’re still on the fence, ask yourself this: are you camping with a partner or do you want the most space possible? Get the MEREZA Double. If you’re sleeping alone in below-freezing weather and want a bag built specifically for tall side sleepers, grab the AZITREK XXL.
