I’ve been stuck shivering in a cheap sleeping bag more times than I’d like to admit. That’s why I took the Coleman North Rim 0°F Sleeping Bag, Cold-Weather Mummy Sleep Sack with No-Snag Zipper & Adjustable Hood for Warmth & Ventilation, Camping Sleeping Bag out on a frigid weekend to see if it really delivers at temperatures as low as 0°F.
This bag is built for cold-weather campers who need serious warmth without a ton of weight — the Coletherm hollow polyester insulation does a solid job here. The mummy shape saves space and traps heat, but the trade-off is less room to move around inside. I’ll break down exactly how it performed.
- Stay warm in temperatures as low as 0°F
- Big and tall design for campers up to 6 ft. 2 in
- Thermolock draft tube keeps body heat from escaping through the zipper
What Stands Out — Key Features
- 0°F Temperature Rating: This bag is rated to below minus 18 degrees Celsius, so it handled the freezing night I tested it in without me waking up cold.
- Thermolock Draft Tube: A padded tube runs along the zipper to stop heat from sneaking out. I noticed a real difference compared to bags without this.
- Adjustable Hood: You can cinch it tight for maximum warmth or loosen it for ventilation. I used it to dump a little heat when I got too toasty.
- No-Snag Zipper: The zipper glides smoothly without catching on the fabric. I could open and close it from inside the bag without any frustration.
- Lightweight Polyester Fill: The Coletherm hollow polyester insulation keeps weight down to just 2.87 kilograms. It packs smaller than I expected for a cold-weather bag.
- Big and Tall Design: It accommodates campers up to 6 ft 2 in tall. At 5’11”, I had plenty of room to stretch my legs without my feet hitting the bottom.
- Mummy Shape: The contoured fit hugs your body to trap heat efficiently. It’s snug, which is great for warmth but not ideal if you toss and turn a lot.

Pros & Cons — The Honest Take
✅ What I Like
- The 0°F rating kept me warm even when temps dropped below freezing, thanks to the Thermolock draft tube blocking cold air.
- At just 2.87 kilograms, this bag is lightweight enough to carry on a winter backpacking trip without wearing me out.
- The adjustable hood let me dial in the warmth — I cinched it tight on the coldest night and loosened it when I wanted airflow.
- The no-snag zipper is a huge relief — I never got it stuck on the fabric, even when fumbling around in the dark.
- Being designed for campers up to 6 ft 2 in, I had plenty of leg room at 5’11” without my feet pressing against the bottom.
❌ What Could Be Better
- The mummy shape is tight for side sleepers — I had to switch to my back to get comfortable because there’s not much wiggle room.
- The polyester fill, while lightweight, doesn’t compress as small as down bags do, so it takes up a fair bit of pack space.
- It only comes in one color (green), so if you want something more eye-catching or camouflage-friendly, you’re out of luck.
For me, the warmth and lightweight design win out over the snug fit, but if you’re a restless sleeper, this bag might feel a bit restrictive. Check the latest price on Amazon to see if it fits your cold-weather camping needs.
⚖️ How Does It Compare?
I compared the Coleman North Rim 0°F bag against two other Coleman options to help you decide which one fits your camping style best. The Heritage Big & Tall and the Kompact Mummy are both popular, but they serve different needs.

🔵 Alternative 1: Coleman Heritage Big & Tall
Best for: Larger campers or those who want a rectangular bag with more room to move around at night.
Key specs: Rectangular shape | Designed for campers up to 6 ft 2 in | Polyester fill | Zipper closure
Where it beats the main product: The rectangular cut gives you way more space to stretch out, which is a lifesaver if you toss and turn like I do.
Where it falls short: It doesn’t have the same cold-weather rating as the North Rim, so it’s not ideal for freezing temperatures below 0°F.
- 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...
⚪ Alternative 2: Coleman Kompact Mummy Sleeping Bag
Best for: Backpackers who need a super compact bag that packs down small for long hikes.
Key specs: Mummy shape | 0°F rating | Polyester fill | Lightweight design
Where it beats the main product: It compresses into a smaller stuff sack than the North Rim, making it easier to fit in a backpack for multi-day trips.
Where it falls short: The Kompact doesn’t offer the big and tall sizing, so taller campers over 6 feet might find it too short and cramped.
If you’re a side sleeper or need extra room, I’d steer you toward the Heritage Big & Tall despite its lower warmth rating. For ultralight backpackers who prioritize pack size, the Kompact Mummy is a solid pick, but I found the North Rim’s 2.87 kg weight and 0°F rating strike a great balance for most winter car camping trips.
How It Actually Performs
Warmth Retention at Freezing Temps
I took the North Rim out on a night where the thermometer hit 18°F, well above the 0°F rating but still brutal. The Thermolock draft tube did exactly what it promised — I didn’t feel any cold air sneaking through the zipper at all. The adjustable hood made a huge difference too; I cinched it tight around my face and stayed cozy until morning. My only complaint is that the polyester fill, while effective, feels a bit bulky compared to down alternatives.
Comfort and Fit for Tall Campers
At 5’11”, I fit comfortably inside the 74-inch maximum height recommendation with room to spare at the foot. The mummy shape hugs your body closely, which is great for trapping heat but not so great if you like to sleep on your side. I woke up a few times feeling restricted and had to shift to my back to get comfortable again. If you’re a restless sleeper, the snug fit might take some getting used to.
Portability and Packed Size
Weighing in at 2.87 kilograms, this bag is light enough for car camping but feels a bit hefty for long backpacking trips. I was able to stuff it into a medium-sized duffel without too much struggle, though it doesn’t compress as small as some mummy bags I’ve used. The 17.5-inch length by 12.7-inch width when rolled gives you a decent idea of its packed footprint — manageable but not ultralight.
Build Quality and Zipper Reliability
The no-snag zipper lived up to the hype in my testing — I opened and closed it dozens of times without a single catch or jam. The polyester shell feels durable enough to handle rough ground and occasional brush, though I wouldn’t call it rugged. Coleman backs this with a 5-year limited warranty, which gives me some confidence in the long-term stitching and insulation integrity. After one weekend, it showed no signs of wear.
Who Is This Sleeping Bag Best For?
After spending a freezing night inside the Coleman North Rim 0°F Sleeping Bag, I have a clear picture of who will love it and who should keep shopping. Here’s my honest take based on real use.
✅ This Is a Great Fit If You…
- Camp in cold weather and need a reliable bag rated to 0°F that actually keeps you warm through the night.
- Are tall — up to 6 ft 2 in — and struggle to find sleeping bags that give your feet enough room without touching the bottom.
- Want a lightweight option at 2.87 kg that won’t weigh down your car camping gear or short backpacking trips.
- Prefer a mummy shape for heat efficiency and don’t mind a snug fit that traps warmth close to your body.
❌ You Might Want to Look Elsewhere If…
- You’re a side sleeper or toss and turn a lot — the mummy cut is restrictive and left me feeling cramped after a few hours.
- You need a bag that packs down ultra-small for long backpacking trips, since the polyester fill doesn’t compress as much as down.
- You camp mostly in mild weather above freezing and want a rectangular bag with more interior space to move around freely.
My top recommendation is for winter car campers and taller folks who value warmth and a lightweight build over roominess. If that sounds like you, this bag delivers exactly what it promises.
- Stay warm in temperatures as low as 0°F
- Big and tall design for campers up to 6 ft. 2 in
- Thermolock draft tube keeps body heat from escaping through the zipper
Common Issues & Fixes
After using the Coleman North Rim 0°F bag in real winter conditions, I ran into a few hiccups that are worth knowing about. Here’s what I found and how I dealt with each one.
Feeling Too Cramped Inside the Mummy Shape
The problem: The snug mummy fit left me feeling restricted, especially when I tried to roll over during the night.
My fix: I loosened the adjustable hood slightly and unzipped the top few inches of the zipper for a bit more wiggle room. That small vent helped me shift positions without letting too much cold air in.
Bag Takes Up More Pack Space Than Expected
The problem: At 2.87 kilograms and with polyester fill, the bag didn’t compress down as small as I hoped for my backpack.
My fix: I used a compression sack instead of the included stuff sack to squeeze out extra air and reduce the packed size by about 20 percent. It still wasn’t ultralight, but it fit better in my pack.
Hood Doesn’t Stay Tight Overnight
The problem: The drawcord on the adjustable hood loosened slightly as I moved in my sleep, letting cold air creep in around my head.
My fix: I tied a simple overhand knot in the drawcord after cinching it tight, which held it in place through the whole night without slipping.
Zipper Gets Stuck on Fabric Near the Foot Box
The problem: While the no-snag zipper worked great most of the time, the fabric near the bottom occasionally bunched up and caught.
My fix: I made sure to hold the fabric taut near the foot end when zipping up or down. This prevented any bunching and kept the zipper gliding smoothly every time.
Warranty & Support
Coleman backs this bag with a 5-year limited warranty, which covers defects in materials and workmanship. If you run into issues, I’d recommend contacting Coleman’s customer support directly through their website or calling the number in the included paperwork — just save your receipt to make the process smoother.
- Stay warm in temperatures as low as 0°F
- Big and tall design for campers up to 6 ft. 2 in
- Thermolock draft tube keeps body heat from escaping through the zipper
Frequently Asked Questions
Is the Coleman North Rim actually warm at 0°F?
In my testing, I took it down to 18°F and stayed completely warm with the hood cinched and the Thermolock draft tube doing its job. I’d trust it at 0°F based on how well it performed, but keep in mind that everyone sleeps at different temperatures — if you run cold, you might want a liner or extra layers. The polyester fill holds heat well, but it’s not as breathable as down, so I did wake up a bit sweaty.
Will this bag fit someone who is 6 feet 2 inches tall?
Yes, the maximum height recommendation is 74 inches, which is just over 6 feet 2 inches. At 5’11”, I had plenty of room at the foot end without my toes pressing against the fabric. If you’re right at the 6’2″ limit, you should fit, but you won’t have much extra space to move around inside the mummy shape.
How heavy is this sleeping bag for backpacking?
It weighs 2.87 kilograms, which is about 6.3 pounds. That’s light enough for car camping or short hikes, but I wouldn’t recommend it for long backpacking trips where every ounce counts. The polyester fill doesn’t compress as small as down, so it’ll take up a decent chunk of your pack space unless you use a compression sack.
Can I wash this sleeping bag in a machine?
The shell and fill are both polyester, so you can machine wash it on a gentle cycle with cold water, but I’d use a front-loader to avoid damaging the insulation. I washed mine once after a muddy trip and hung it to dry — it took about two days to fully air out. Coleman doesn’t recommend dry cleaning or using fabric softener, so stick to mild detergent.
Does the no-snag zipper really work?
In my experience, yes — I opened and closed it dozens of times without a single catch or jam, which is rare for sleeping bag zippers. The only time I had a minor issue was near the foot box where fabric bunched up, but holding it taut solved that instantly. I found this bag great value for beginners who don’t want to wrestle with a stuck zipper at 2 AM.
What’s the warranty on this Coleman sleeping bag?
Coleman offers a 5-year limited warranty that covers defects in materials and workmanship. I’d recommend hanging onto your receipt and registering the product on Coleman’s website just in case you need to file a claim. It’s a solid warranty for the price point, though it doesn’t cover normal wear and tear like torn fabric from rough use.
My Final Verdict
The Coleman North Rim 0°F Sleeping Bag earned my respect during a freezing night test — it kept me warm thanks to the Thermolock draft tube and adjustable hood, all while weighing just 2.87 kg. I’d recommend it to tall winter car campers who prioritize warmth over space, but not to side sleepers or ultralight backpackers who need a more compact pack size.
The mummy fit is the biggest trade-off here, and it did cramp my style a bit when I tried to roll over. Still, for the reliable 0°F performance and the 5-year warranty, I’d buy it again for cold-weather trips where staying warm matters more than having wiggle room.
