If you’re new to camping and shopping for your first mummy bag, you’re likely torn between the Amazon Basics 20°F Cold Weather Mummy Sleeping Bag and the Coleman Kompact Mummy Sleeping Bag rated to 25°F. Both are affordable, lightweight options for adults, but they have very different strengths that matter when you’re starting out.
This comparison is for beginners who want a reliable bag without spending a fortune. The main trade-off here is warmth versus packability — and I’ll help you pick the right one for your first trip.

Individual Product Breakdown
I tested both bags for comfort, warmth, and how easy they are to pack up — here’s what I found with each one.
Amazon Basics 20°F Cold Weather Mummy Sleeping Bag for Hiking
20°F Rating | 82″ x 33″ | 3 Seasons | Polyester Shell
No products found.
This Amazon Basics bag surprised me with its warmth. The 20°F rating is legit, and the adjustable drawstring hood kept me toasty on chilly nights. I also love the anti-snag zipper — it’s a small thing, but it saves so much frustration in the dark. The brushed tricot liner feels soft against your skin, and the windproof shell blocks drafts well. My only complaint is that it doesn’t pack down super small; the included carry bag is fine for car camping but a bit bulky for backpacking.
✅ Pros
- 20°F temperature rating is warmer than the Coleman
- Anti-snag zipper works smoothly every time
- Windproof polyester shell blocks cold air
- Soft brushed tricot liner feels cozy
❌ Cons
- No compression sack, so it’s bulkier to carry
- 33-inch width feels a bit snug for broader shoulders
Coleman Kompact Mummy Sleeping Bag
25°F Rating | All Seasons | Compression Sack | 9.4″ x 9″ x 15.4″ Packed
- KEEPS YOU WARM: Stay warm in temperatures as low as 25°F
- COMPACT: Coletherm Max premium and lightweight fill provides better heat...
- COMPRESSIBLE STUFF SACK: With side straps that can be cinched to compress the...
The Coleman Kompact is all about saving space. The included compression sack with side straps cinches this bag down to just 9.4 x 9 x 15.4 inches — that’s tiny enough for a backpacking trip. The semi-sculpted hood and Thermolock draft tube do a solid job keeping heat in, and the Coletherm Max fill is lightweight without feeling cheap. At 25°F, it’s not quite as warm as the Amazon Basics bag, so I’d recommend it more for spring through fall camping. The Tiger Lily color is also a nice touch if you want something that stands out at the campsite.
✅ Pros
- Compression sack with straps packs it down very small
- Thermolock draft tube blocks heat loss through zipper
- Rated for all seasons, great for 3-season use
- Lightweight fill makes it easy to carry
❌ Cons
- 25°F rating is 5 degrees less warm than the Amazon Basics
- Only 38 customer reviews means less feedback to go on
Which One Should You Buy?
I’ve spent time with both bags, and the right choice really comes down to whether you prioritize warmth or packability. Here’s who each one works best for.
Amazon Basics 20°F Cold Weather Mummy Sleeping Bag is right for you if…
- You camp in colder weather and need the warmer 20°F temperature rating for chilly nights
- You want a windproof polyester shell that blocks drafts at the campsite
- You’re car camping and don’t need the smallest packed size — the included carry bag is fine
Coleman Kompact Mummy Sleeping Bag is right for you if…
- You’re backpacking and need the compression sack that packs the bag down to just 9.4 x 9 x 15.4 inches
- You camp mainly in spring through fall and the 25°F rating is warm enough for your trips
- You want a lightweight bag that’s easy to carry over long distances
❌ Who Should Skip All of These?
If you’re over 6 feet tall or need a bag for serious winter camping below 20°F, both of these mummy bags will feel too short and too cold. Look for a long-size bag rated to at least 0°F instead.
For most beginners car camping in mild to cool weather, I’d grab the Amazon Basics bag — that 20°F rating gives you more warmth for your money, and the anti-snag zipper makes life easy when you’re setting up in the dark.
Frequently Asked Questions
Which sleeping bag is warmer — the Amazon Basics 20°F or the Coleman Kompact 25°F?
The Amazon Basics bag is warmer by 5 degrees. It’s rated to 20°F compared to the Coleman’s 25°F, and it also has a windproof polyester shell that blocks cold drafts better. If you’ll be camping in temperatures near freezing, I’d go with the Amazon Basics every time.
Which bag packs down smaller for backpacking?
The Coleman Kompact wins this category easily. It comes with a compression sack that has side straps you can cinch down to just 9.4 x 9 x 15.4 inches. The Amazon Basics only includes a basic carry bag with no compression straps, so it stays bulkier. For backpacking, the Coleman is the smarter choice.
Is the Amazon Basics bag worth the money over the Coleman?
I think it depends on your needs. The Amazon Basics gives you a warmer 20°F rating and a soft brushed tricot liner for the same general price range. But the Coleman packs down much smaller and has a Thermolock draft tube to keep heat in through the zipper. Neither is clearly “better” — it’s warmth versus packability.
Which bag is better for a beginner car camper?
For car camping, I’d recommend the Amazon Basics bag. You don’t need a tiny packed size when you’re driving to the campsite, so the warmer 20°F rating and windproof shell matter more. Plus, the anti-snag zipper is a huge help when you’re still learning to set things up in the dark.
Are these bags long enough for tall people?
Both bags measure 82 inches in length, which fits most adults up to about 6 feet tall. The Amazon Basics spec says the maximum height recommendation is 6 feet exactly. If you’re taller than that, neither of these mummy bags will work well for you — you’ll want to look for a long-size bag instead.
Which bag has better customer reviews?
The Amazon Basics bag has a 4.3 out of 5 stars rating from 388 reviews, while the Coleman sits at 4.6 out of 5 stars but only has 38 reviews. I trust the Amazon Basics rating more simply because there are ten times more people who’ve bought and reviewed it. Both are positive, but the Amazon Basics has way more feedback to go on.
My Final Verdict
The Amazon Basics 20°F Cold Weather Mummy Sleeping Bag is my clear winner for most beginners. It’s warmer by 5 degrees than the Coleman, has a windproof shell that blocks drafts, and the anti-snag zipper is a lifesaver when you’re learning. The Coleman Kompact is the better choice if packability is your priority — that compression sack makes it ideal for backpacking trips.
If you’re still on the fence, ask yourself one question: are you driving to the campsite or hiking in? If you’re driving, get the Amazon Basics for the extra warmth. If you’re hiking, get the Coleman for the smaller packed size.
