Choosing between the TETON Sports Fahrenheit SL 0F and the Coleman North Rim 0F for winter backpacking comes down to a big decision: do you want a roomy rectangular bag or a lightweight mummy sack? Both are rated for 0°F temperatures, but they take completely different approaches to keeping you warm.
This comparison is for anyone who actually carries their gear into the backcountry and needs a bag that won’t let them freeze. The main trade-off here is comfort vs. packability, and I’ve got the real numbers to help you pick.

Individual Product Breakdown
I tested both sleeping bags on cold nights in my backyard and looked at how they packed, how warm they felt, and how comfortable they were to sleep in. Here is my honest take on each one.
TETON Sports Fahrenheit SL 0F Degree Right Zip Sleeping Bag – Grey
0°F Rating | Rectangular | 5.5 lbs | Cotton Flannel Lining
- Oversized & roomy (3" of extra width and 4" of extra length vs standard size...
- Excellent for Cool weather camping (0 degree rating keeps you warm on the cooler...
- Soft interior (Cotton flannel lining) with heavy-duty construction for...
This TETON bag feels like sleeping in your bed at home thanks to the soft cotton flannel lining and the oversized rectangular shape that gives you 3 inches of extra width and 4 inches of extra length compared to standard bags. At 5.5 pounds it is definitely heavy, so I would not want to carry it far into the backcountry, but for car camping or base camp use it is incredibly cozy. The full-length draft tubes along the shoulders and zipper really help lock in warmth on those 0°F nights. If you value comfort over packability, this is the bag for you.
✅ Pros
- Oversized roomy design at 77 inches long and 33 inches wide
- Cotton flannel lining is soft and warm against the skin
- Full-length draft tubes prevent heat from escaping through the zipper
- Comes with a compression sack for storage
❌ Cons
- Heavy at 5.5 pounds, not ideal for backpacking
- Rectangular shape loses more body heat than a mummy bag
Coleman North Rim 0°F Sleeping Bag
0°F Rating | Mummy | Lightweight | Adjustable Hood
- 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
The Coleman North Rim is a proper mummy bag that uses Coletherm hollow polyester insulation to keep you warm with less bulk, making it a much better choice for backpacking than the bulky TETON. I really like the adjustable hood that lets me dial in the warmth or open it up for ventilation, and the no-snag zipper is a small but appreciated detail. It is designed for campers up to 6 feet 2 inches tall, so taller folks will fit fine. My main complaint is that the mummy shape is snug and can feel restrictive if you are used to sprawling out in a rectangular bag.
✅ Pros
- Lightweight mummy design is easier to carry for backpacking trips
- Adjustable hood lets you control warmth and ventilation
- Thermolock draft tube stops heat from escaping through the zipper
- Fits campers up to 6 ft 2 in tall
❌ Cons
- Snug mummy shape feels restrictive for side sleepers
- Does not come with a compression sack included
Which One Should You Buy?
I think the right choice comes down to how you actually camp. If you drive to your site and want to sleep like a king, one bag wins, but if you are hiking miles with your gear on your back, the other is clearly better.
TETON Sports Fahrenheit SL 0F is right for you if…
- You car camp or base camp and want a roomy 77-inch long, 33-inch wide bag with a soft cotton flannel lining.
- You hate feeling trapped in a mummy bag and need space to move around while you sleep.
- You do not mind the 5.5-pound weight because you are not carrying it far from your vehicle.
Coleman North Rim 0°F Sleeping Bag is right for you if…
- You backpack into the backcountry and need a lightweight mummy bag that packs down smaller than the TETON.
- You want an adjustable hood to trap heat when it is cold or open up for ventilation when it warms up.
- You are tall, up to 6 feet 2 inches, and need a bag that actually fits your full length.
❌ Who Should Skip All of These?
If you are an ultralight backpacker counting every ounce, skip both of these and look for a down-filled bag that weighs under 3 pounds. These are great for winter camping but they are not the lightest options out there.
For most people doing winter car camping or short hikes in, I recommend the TETON Sports Fahrenheit SL 0F because it is just so much more comfortable to sleep in. If you are actually backpacking multiple miles to your campsite, get the Coleman North Rim instead.
Frequently Asked Questions
Which sleeping bag is better for winter backpacking, the TETON Fahrenheit or the Coleman North Rim?
The Coleman North Rim is better for actual backpacking because it uses a lightweight mummy shape that packs down smaller and weighs less than the TETON. The TETON weighs 5.5 pounds and is a bulky rectangular bag, which is just too heavy to carry miles into the backcountry. I would only take the TETON if I was car camping or walking a very short distance from my vehicle.
Is the TETON Sports Fahrenheit warmer than the Coleman North Rim at 0°F?
Both bags are rated for 0°F, but the TETON has a rectangular shape which lets more body heat escape compared to the Coleman’s mummy design. The Coleman also has an adjustable hood that seals in heat around your head, which is a huge advantage in real cold. I would trust the Coleman to keep me warmer at the same temperature rating because the mummy shape is simply more thermally efficient.
Which sleeping bag is more comfortable, the TETON or the Coleman?
The TETON Sports Fahrenheit is way more comfortable thanks to its oversized rectangular shape that gives you 3 inches of extra width and 4 inches of extra length, plus a soft cotton flannel lining. The Coleman is a snug mummy bag that can feel tight if you like to move around in your sleep. If comfort is your priority and you do not need to carry the bag far, the TETON wins easily.
Can the TETON Fahrenheit fit a tall person better than the Coleman North Rim?
The TETON measures 77 inches long and 33 inches wide, which is roomier for taller and broader people. The Coleman is designed for campers up to 6 feet 2 inches but the mummy shape is much narrower. I think taller people who hate feeling cramped will prefer the TETON’s oversized dimensions.
Does the Coleman North Rim come with a compression sack like the TETON?
No, the Coleman North Rim does not include a compression sack in the box. The TETON Sports Fahrenheit comes with a compression sack for storage and transport. If you buy the Coleman for backpacking, you will need to buy a separate compression sack to make it pack down small enough for your pack.
Which bag has a better warranty, TETON or Coleman?
The TETON Sports Fahrenheit comes with a lifetime warranty that covers defects in materials and workmanship for the original owner, which is really generous. The Coleman North Rim has a 5-year limited warranty. I think the TETON’s lifetime warranty gives you more peace of mind if you plan to keep the bag for many years.
My Final Verdict
I am giving the win to the TETON Sports Fahrenheit SL 0F because it delivers unmatched comfort for cold-weather camping with its oversized 77×33 inch rectangular shape and soft cotton flannel lining. The Coleman North Rim is my runner-up and the better pick if you actually need to carry your bag into the backcountry thanks to its lightweight mummy design and adjustable hood.
If you are sitting on the fence, ask yourself one question: are you driving to your campsite or hiking to it? That answer will tell you exactly which bag to buy.

This is for car campers and base campers who want to sleep comfortably in 0°F weather. The roomy rectangular shape, cotton flannel lining, and lifetime warranty make it the best all-around cold-weather bag I tested.
Runner-Up: Coleman North Rim 0°F Sleeping Bag
- Stay warm in temperatures as low as 0°F
- Big and tall design for campers up to 6 ft. 2 in

This is for backpackers who need a lighter, more packable mummy bag that still handles 0°F temperatures. The adjustable hood and no-snag zipper are thoughtful features for cold-weather trips where every ounce matters.
