Picking the right mummy sleeping bag means deciding how much cold you’ll actually face. The TETON Sports bag is rated down to 5°F, the Coleman Kompact hits 25°F, and the Retrospec Dream comes in at 30°F — three very different temperature targets for three very different kinds of campers.
I’ve spent time with all three to help you figure out which one fits your trips. The big trade-off here is warmth versus weight and price, and I’ll break down exactly where each bag shines so you can stop guessing and start sleeping better.

Individual Product Breakdown
I crawled inside each bag, checked the zippers, tested the draft tubes, and weighed the stuff sacks to give you the real story on warmth, comfort, and portability.
TETON Sports 5F Degree Sleeping Bag
5°F Rating | 1-Person Mummy | Polyester Ripstop | Compression Sack Included
- LIGHTWEIGHT AND WARM: Tired of your feet getting cold? This is the sleeping bag...
- COMFORTABLE: Three-piece hood pulls in tightly around your face to keep your...
- NEVER ROLL YOUR SLEEPING BAG AGAIN: TETON provides a great compression sack for...
This TETON Sports bag is the warmest of the bunch by a mile with its 5°F temperature rating. I love the three-piece hood that cinches tight around your face and the added insulation in the footbox — my toes never got cold during my test. The full-length zipper draft tube does a great job keeping warm air in, and the included compression sack with heavy-duty straps makes stuffing it a breeze. It’s heavier than the other two, so it’s best for car camping or cold-weather trips where weight isn’t your main concern.
✅ Pros
- Exceptional 5°F rating for serious cold-weather camping
- Three-piece hood keeps your entire head warm
- Lifetime warranty from TETON Sports
- Compression sack with heavy-duty straps included
❌ Cons
- Heavier and bulkier than the other two options
- Overkill for summer or mild-weather camping trips
Coleman Kompact Mummy Sleeping Bag
25°F Rating | 1-Person Mummy | Coletherm Max Fill | Compressible Stuff Sack
- 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 hits a sweet spot for three-season campers with its 25°F rating and lightweight Coletherm Max fill that packs down small. I was impressed by the Thermolock draft tube along the zipper — it really does prevent heat from escaping on chilly nights. The semi-sculpted hood locks in warmth without feeling restrictive, and the compressible stuff sack with side straps cinches it down to just 9.4 x 9 x 15.4 inches. My only gripe is that the 25°F rating might feel a bit optimistic on truly freezing nights.
✅ Pros
- Compresses to a compact 9.4 x 9 x 15.4 inches for packing
- Thermolock draft tube prevents heat loss through the zipper
- Lightweight Coletherm Max fill offers good warmth-to-weight ratio
- Semi-sculpted hood locks in heat effectively
❌ Cons
- 25°F rating may feel borderline in actual freezing conditions
- Only 38 customer reviews at time of testing, less proven than competitors
Retrospec Dream Mummy Sleeping Bag
30°F Rating | 1-Person Mummy | Water-Resistant Shell | 2 lbs 8 oz
- PROTECTION FROM THE ELEMENTS - Stay warm, dry, and comfortable all night long...
- COMFORTABLE MUMMY DESIGN - Designed to provide the most efficient insulation...
- STUFF SACK INCLUDED—Your lightweight sleeping bag easily packs down to fit...
The Retrospec Dream is the lightest bag here at just 2 lbs 8 oz for the regular size, making it a solid pick for backpackers who count every ounce. I like the water-resistant inner and outer shell that adds a layer of protection against damp ground or tent condensation, and the zippered stash pocket is a nice touch for keeping your phone or lip balm handy. The relaxed mummy shape gives you a bit more wiggle room than traditional mummies, but the 30°F rating means it’s best for summer and early fall trips only. The draw cords are easy to adjust even in the dark, which I appreciated during my overnight test.
✅ Pros
- Lightest option at 2 lbs 8 oz for easy backpacking
- Water-resistant inner and outer shell for moisture protection
- Zippered stash pocket keeps small essentials secure
- Differentiated draw cords are easy to adjust in the dark
❌ Cons
- 30°F rating limits it to warmer weather use only
- Fall-only season rating means it’s not ideal for winter camping
Which One Should You Buy?
I know that picking the right sleeping bag comes down to where you camp and how cold it actually gets. Let me match each bag to the specific camper who will love it most.
TETON Sports 5F Degree Sleeping Bag is right for you if…
- You camp in real winter conditions where temps drop below freezing — the 5°F rating is the warmest of the three by a wide margin
- You drive to your campsite and don’t mind a heavier bag since the compression sack makes stuffing easy
- You want a lifetime warranty from a brand that stands behind its gear for years of use
Coleman Kompact Mummy Sleeping Bag is right for you if…
- You need a three-season bag that compresses down to just 9.4 x 9 x 15.4 inches for backpacking trips
- You camp in temperatures down to 25°F and want a Thermolock draft tube to keep the cold air out
- You trust the Coleman brand for reliable outdoor gear and want a lightweight option for hiking and camping
Retrospec Dream Mummy Sleeping Bag is right for you if…
- You’re a backpacker who counts every ounce — the regular size weighs only 2 lbs 8 oz
- You mostly camp in summer or early fall when overnight temps stay above 30°F
- You want a water-resistant shell and a handy zippered stash pocket for your phone or lip balm
❌ Who Should Skip All of These?
If you’re a hardcore ultralight backpacker who needs a bag under 2 pounds, or if you camp in extreme conditions below 0°F, none of these mummy bags will cut it. You’d be better off looking at down-filled options with higher fill power or expedition-grade bags rated for sub-zero temps.
For most campers, my clearest recommendation is the TETON Sports 5F bag if you face real cold, or the Coleman Kompact if you want the best all-around balance of warmth and packability for three-season use.
Frequently Asked Questions
Which sleeping bag is warmest — the TETON Sports, Coleman Kompact, or Retrospec Dream?
The TETON Sports bag is the clear winner here with a 5°F temperature rating. That’s 20 degrees warmer than the Coleman Kompact at 25°F and 25 degrees warmer than the Retrospec Dream at 30°F. If you’re camping in freezing conditions, the TETON is the only one I’d trust to keep you warm all night.
Is the TETON Sports 5F bag worth the extra money over the Coleman Kompact?
It depends on how cold you camp. If you regularly face temperatures below 25°F, then yes — the TETON’s 5°F rating and added footbox insulation are absolutely worth it. But if you’re a three-season camper who rarely sees freezing temps, the Coleman Kompact gives you a better warmth-to-weight ratio and packs down smaller for less money.
Which bag is best for backpacking — the Coleman Kompact or Retrospec Dream?
I’d give the edge to the Retrospec Dream for backpacking because it weighs only 2 lbs 8 oz in the regular size, making it the lightest of the three. The Coleman Kompact is close behind with its compressible stuff sack that cinches to 9.4 x 9 x 15.4 inches, but the Retrospec wins for pure weight savings on long hikes.
Can the Retrospec Dream handle cold weather camping?
Not really — the Retrospec Dream is rated for 30°F and the manufacturer lists it as a fall-season bag. I wouldn’t take it out in freezing or below-freezing conditions. It’s best for summer car camping, mild spring trips, or as a backup bag for warmer nights.
Which bag has the best warranty?
The TETON Sports bag comes with a lifetime warranty that covers defects in materials and workmanship for the original owner. Coleman offers a limited warranty on the Kompact, and Retrospec also has a limited warranty on the Dream. If long-term coverage matters to you, the TETON is the only one with a lifetime guarantee.
Do these sleeping bags come with a compression sack?
Yes, all three include a stuff sack or compression sack. The TETON Sports bag comes with a compression sack that has heavy-duty straps for tight packing. The Coleman Kompact includes a compressible stuff sack with side straps that cinch it down small. The Retrospec Dream comes with a standard stuff sack for easy carrying.
My Final Verdict
The TETON Sports 5F bag is my overall winner because it’s the only one built for real winter camping with a 5°F rating, a three-piece hood, and a lifetime warranty. The Coleman Kompact takes the runner-up spot for three-season campers who want a bag that compresses to just 9.4 x 9 x 15.4 inches and offers solid warmth down to 25°F without the bulk.
If you’re still on the fence, ask yourself one question: what’s the coldest temperature you’ll actually sleep in? If it’s below 25°F, get the TETON. If it’s above that, the Coleman Kompact gives you better portability and a lower price for milder trips.
