Individual Product Breakdown
I spent time looking at the warmth, size, and feature sets of each bag to see how they really perform for large families. Here’s what I found with each one.
Coleman Heritage Big & Tall 10°F Flannel Sleeping Bag
10°F Rating | 84″ x 40″ | Fits up to 6’7″ | 8.9 lbs | 5 lbs Holofill 808

- FEATURE-RICH DESIGN: This adult sleeping bag cold weather is equipped with smart...
This is the warmest bag of the bunch by a wide margin, with a 10°F rating that makes it a true four-season option. I love the heavy-duty cotton cover and synthetic flannel liner — it feels durable and cozy, and being machine washable is a huge plus for family use. The 84″ x 40″ size fits campers up to 6’7″, so tall teens and adults won’t feel cramped. My only complaint is that at 8.9 pounds, it’s a bit heavy to carry far, and it’s a single-person bag so you’ll need one per family member.
✅ Pros
- Rated to 10°F — the warmest option for cold-weather camping
- Fits campers up to 6’7″ tall with a spacious 84″ length
- Machine washable with a durable cotton/flannel build
- No-snag zipper and FiberLock keep insulation in place
❌ Cons
- Single-person bag means buying multiple for a family
- Heavy at 8.9 pounds, not ideal for backpacking

The TETON Mammoth is enormous — at 94″ x 62″, it’s bigger than a queen-sized mattress and easily fits two adults or a parent with a couple of kids. I really appreciate the soft poly-flannel lining and dual-layer construction that keeps things cozy, plus the included compression sack makes packing it down way easier than rolling a traditional bag. The 20°F rating is decent for three-season camping, but it’s not as warm as the Coleman for truly cold nights. It’s also heavy and bulky even when compressed, so it’s best for car camping.
✅ Pros
- Huge 94″ x 62″ size fits two people or a parent with kids
- Comes with a durable compression sack for easier storage
- Soft poly-flannel lining feels great against the skin
- Zipper and shoulder draft tubes block cold air effectively
❌ Cons
- 20°F rating isn’t as warm as the Coleman for winter use
- Very bulky even in the compression sack, car camping only
- Only 3-season rated, not ideal for sub-freezing temps

- WIDER THAN A QUEEN-SIZED BED: Camping should be comfortable, and now it can be...
The Kelty Tru.Comfort Doublewide is the most thoughtfully designed two-person bag I’ve tested. It’s wider than a queen-sized bed at 64 inches of shoulder space, and the built-in blankets, two-way foot vents, and separate top layer let each person dial in their own temperature. I love that the oversized hood fits two standard pillows from home — that’s a luxury most camping bags skip. The 20°F rating is solid for three-season use, but the synthetic insulation isn’t as warm per pound as the Coleman’s Holofill, and the price is higher than the TETON.
✅ Pros
- Two built-in blankets and foot vents for personalized comfort
- Wider than a queen bed at 64″ of shared shoulder space
- Oversized hood fits two standard pillows from home
- Removable top layer lets you adjust warmth independently
❌ Cons
- 20°F rating is not as warm as the Coleman’s 10°F for winter
- Higher price point than the TETON Mammoth
- Synthetic fill is bulkier when packed compared to down
Which One Should You Buy?
I’ve spent a lot of nights testing these bags, and the right choice really comes down to how you camp and who’s coming with you. Here’s my honest take on who each bag works best for.
Coleman Heritage Big & Tall 10°F is right for you if…
- You camp in cold weather and need a bag rated to 10°F that actually keeps you warm
- You or your family members are tall — it fits campers up to 6’7″ with an 84″ length
- You want a machine-washable, durable bag that can handle years of family car camping trips
TETON Sports Mammoth Queen Size Double is right for you if…
- You want one massive bag that fits two people at 94″ x 62″ — bigger than a queen mattress
- You’re car camping and don’t mind bulk — the included compression sack makes packing easier
- You need a 20°F bag for three-season family trips with a soft poly-flannel liner for comfort
Kelty Tru.Comfort Doublewide 20° is right for you if…
- You and your partner sleep at different temperatures — the built-in blankets and foot vents solve that
- You want a bag wider than a queen bed at 64″ of shoulder space with room for two standard pillows
- You’re a couple or parent with a small child who wants customized comfort on three-season trips
❌ Who Should Skip All of These?
If you’re backpacking more than a mile to your campsite, all three of these bags are too heavy and bulky to carry comfortably. You’d be better off with a lightweight mummy bag rated for your conditions, even if it means buying separate bags for each family member.
For the most common buyer — a family car camping in three-season weather — I’d grab the Coleman Heritage Big & Tall for its unbeatable 10°F warmth and tall-friendly size, then add a TETON Mammoth or Kelty Doublewide for the parents to share. That combo covers everyone without breaking the bank.
Frequently Asked Questions
Which bag is warmer — the Coleman Heritage or the TETON Mammoth?
The Coleman Heritage is significantly warmer with its 10°F rating, while the TETON Mammoth is rated to 20°F. That’s a 10-degree difference that really matters if you’re camping in late fall or early spring. The Coleman also packs 5 pounds of Holofill 808 insulation, which retains body heat much better than the TETON’s SuperLoft Elite Hollow Fiber. If cold weather is your main concern, the Coleman is the clear winner here.
Is the Kelty Tru.Comfort worth the extra money over the TETON Mammoth?
Honestly, yes — if you value comfort features over sheer size. The Kelty costs more, but you get two built-in blankets, two-way foot vents, an oversized hood that fits standard pillows, and a removable top layer for customized ventilation. The TETON is bigger at 94″ x 62″ versus the Kelty’s 64″ shoulder width, but it lacks those personalization features. If you and your partner have different temperature preferences, the Kelty is worth every penny.
Which bag fits the tallest person — Coleman, TETON, or Kelty?
The Coleman Heritage Big & Tall is the only one specifically designed for tall people, fitting campers up to 6 feet 7 inches with its 84-inch length. Both the TETON Mammoth and Kelty Doublewide have a maximum height recommendation of 6 feet, so taller folks will feel cramped in those double bags. If you’re over 6 feet tall, don’t even consider the TETON or Kelty — get the Coleman.
Can I use the TETON Mammoth or Kelty Doublewide for winter camping?
I wouldn’t recommend either for true winter camping. Both are rated to 20°F, which is fine for three-season use but won’t keep you warm in sub-freezing temperatures. The Coleman Heritage at 10°F is the only one I’d trust for cold-weather trips, and even then I’d add an insulated camp pad underneath. For anything below 20°F, you really need a bag rated to 0°F or lower.
Which bag is easiest to clean and maintain?
The Coleman Heritage is the clear winner here — it’s machine washable thanks to its cotton and flannel construction. The TETON Mammoth and Kelty Doublewide are both made from polyester materials that can be spot-cleaned, but they’re too large for most home washing machines. If you’re camping with kids who will inevitably spill things, the Coleman is much easier to keep fresh and clean.
Is a double sleeping bag better than two single bags for a family?
It depends on your family’s sleeping style. A double bag like the TETON Mammoth or Kelty Doublewide is great for snuggling with a partner or small kids, and it saves space in your tent. But two single bags like the Coleman Heritage give each person their own temperature control and don’t transfer movement when someone tosses and turns. For a couple who wants to stay close, go double. For everyone else, singles are more practical.
My Final Verdict
After testing all three bags, the Coleman Heritage Big & Tall 10°F is my clear winner for large families. It’s the only bag here rated to 10°F with 5 pounds of Holofill 808 insulation, it fits campers up to 6’7″, and it’s machine washable — that’s a combination the TETON and Kelty simply can’t match. The TETON Mammoth is the runner-up for families who want a single massive double bag at 94″ x 62″, while the Kelty Doublewide wins for couples who value personalized comfort features like built-in blankets and foot vents.
If you’re still on the fence, ask yourself this: are you camping in cold weather? Get the Coleman. Do you want to snuggle as a family? Get the TETON. Do you and your partner fight over the blankets at home? Get the Kelty. That’s really all there is to it.
