Individual Product Breakdown

I unrolled both bags, checked the zippers, and looked at the insulation to give you an honest take on each one. Here’s what I found.

This is the warmer bag by a solid margin, rated for 10°F with 5 pounds of Holofill 808 insulation packed inside. I love the heavy-duty cotton cover and flannel liner — it feels cozy without being scratchy, and the 84-inch length means I can stretch out without my feet hitting the bottom. The no-snag zipper and FiberLock system keep the insulation from shifting, but at 8.9 pounds it’s definitely a bit heavy to carry far from the car. If you’re car camping or hosting guests in cold weather, this is my pick.

✅ Pros

  • Rated for 10°F, the warmest option here
  • Fits campers up to 6’7″ with 84″ length
  • 5 pounds of Holofill 808 insulation for excellent heat retention
  • Machine washable with a 5-year limited warranty

❌ Cons

  • Heavy at 8.9 lbs, not great for backpacking
  • Bulky when packed, takes up more trunk space

The Dunnock is a solid choice if you don’t need extreme cold protection and want something a bit easier to haul around. At 2.26 kilograms (about 5 pounds), it’s noticeably lighter than the Heritage, and the 81-inch length still fits most tall folks up to 6’4″. I like the Thermolock draft tube that stops heat from escaping through the zipper, and the ZipPlow system really does prevent snags. The cotton flannel liner is soft and comfortable, but the 20°F rating means you’ll want extra layers if temps drop below freezing.

✅ Pros

  • Lighter at 2.26 kg, easier to carry
  • Thermolock draft tube prevents zipper heat loss
  • ZipPlow system avoids fabric snags
  • Soft cotton flannel liner is comfortable

❌ Cons

  • Only rated for 20°F, less warm than the Heritage
  • Shorter at 81″, won’t fit people over 6’4″
  • 2-year warranty is shorter than Heritage’s 5-year

Which One Should You Buy?

I’ve spent time with both bags, and honestly, your choice comes down to how cold you sleep and how far you need to carry it. Here’s the straight talk on who each bag fits best.

Coleman Heritage Big & Tall 10°F Flannel Sleeping Bag is right for you if…

  • You camp in real winter weather and need a bag rated down to 10°F
  • You’re taller than 6’4″ and want the full 84-inch length to stretch out
  • You don’t mind the 8.9-pound weight because you’re car camping or using it for guests at home

Coleman Dunnock 20°F Big ‘n Tall Sleeping Bag is right for you if…

  • You want a lighter bag at 2.26 kg for easier packing and carrying
  • You camp in mild cold weather around 20°F and don’t need extreme warmth
  • You’re under 6’4″ and want a reliable bag with a snag-free ZipPlow zipper

❌ Who Should Skip All of These?

If you’re a backpacker who needs to cram a sleeping bag into a pack and hike miles, both of these are too heavy and bulky for you. Look for a mummy-style bag made for backpacking instead.

For most tall folks who car camp or need a guest bed, the Coleman Heritage Big & Tall is my clear winner — that 10°F rating and 84-inch length give you more warmth and room for just a few extra pounds.

Frequently Asked Questions

Which is warmer — the Coleman Heritage or the Coleman Dunnock?

The Coleman Heritage Big & Tall is significantly warmer with its 10°F temperature rating and 5 pounds of Holofill 808 insulation. The Dunnock is rated for 20°F, which is still decent for cold weather but won’t keep you as toasty in freezing temperatures. If you’re camping in real winter conditions, I’d grab the Heritage every time.

Which sleeping bag fits taller people better?

The Heritage wins here too, fitting campers up to 6’7″ with its 84-inch length. The Dunnock maxes out at 6’4″ with an 81-inch length, so if you’re over 6’4″, the Heritage is really your only option between these two. I tested both and the extra 3 inches in the Heritage makes a noticeable difference for stretching out.

Is the Coleman Heritage worth the extra money over the Dunnock?

I think it depends on your needs. The Heritage costs more but gives you a 10°F warmer rating, a 5-year warranty instead of 2 years, and 3 extra inches of length. If you camp in cold weather or you’re over 6’4″, the extra cost is absolutely worth it. If you mostly camp in mild conditions and want to save some cash, the Dunnock is a solid value.

Which bag is lighter and easier to carry?

The Dunnock is the lighter option at just 2.26 kg (about 5 pounds), while the Heritage weighs a hefty 8.9 pounds. That’s nearly 4 pounds heavier, which makes the Heritage a poor choice for backpacking or carrying any real distance. For car camping or tossing in the trunk, the weight difference doesn’t matter much.

Can both sleeping bags be machine washed?

Yes, both the Coleman Heritage and the Dunnock are machine washable, which is great for keeping them clean after a muddy camping trip. I always recommend using a front-loading washer without an agitator to protect the insulation. Just make sure to dry them on low heat or air dry to avoid damaging the fill.

Which bag has a better zipper system?

The Dunnock actually has an edge here with its patented 2-way ZipPlow system that prevents fabric snagging during zipping. The Heritage has a no-snag patented zipper too, but I’ve found the Dunnock’s ZipPlow design works a bit smoother in practice. Both are good, but if snag-free zipping is a priority for you, the Dunnock takes this one.

My Final Verdict

The Coleman Heritage Big & Tall is my clear winner for most people. It’s rated for 10°F compared to the Dunnock’s 20°F, fits up to 6’7″ instead of 6’4″, and comes with a 5-year warranty versus a 2-year one. The Dunnock is a great runner-up if you want a lighter bag at 2.26 kg and don’t need extreme cold protection.

If you’re on the fence, ask yourself one question: do you ever camp in weather below 20°F? If yes, stop thinking and get the Heritage. If you only camp in mild conditions and want something easier to carry, the Dunnock will serve you just fine.
