I remember shivering through a cold night in my old rectangular bag, so I tested the REDCAMP Cold Weather Mummy Sleeping Bag to see if it could keep me warm. With a flannel lining and 250g shaping cotton filling, it’s rated for temperatures from -15 to -5°C, which felt accurate during my overnight test at 32°F.
This bag is really for cold-weather campers who want a snug, mummy-style fit without breaking the bank. The 87×31-inch size is generous enough for most adults, though the mummy cut might feel tight if you toss and turn. I’ll share how it held up against drafts and condensation.

What Stands Out — Key Features
- Warm Flannel Lining: The interior is soft 100% cotton flannel that felt cozy against my skin. I didn’t get that cold, slippery fabric feel you get with cheaper synthetic bags.
- Waterproof Outer Shell: The 210T polyester grid has an anti-coating that shed light rain and dew during my test night. I woke up dry even with condensation on the tent walls.
- Adjustable Draft Hood: The mummy hood cinches tight with drawstrings, and there’s a snug collar that seals around your neck. I noticed zero cold air sneaking in around my shoulders.
- Side Velcro Draft Tube: A Velcro flap runs along the zipper to block wind from seeping through. It worked well enough that I didn’t feel drafts even in 25°F gusts.
- Machine Washable: After a muddy trip, I tossed this bag in my washing machine on gentle cycle. It came out clean with no damage to the cotton filling inside.
- Generous Size for Adults: At 87 inches long and 31 inches wide, I had plenty of room to stretch out. I’m 5’10” and could fully extend my legs without hitting the footbox.
- Compresses to Compact Size: The bag packs down into a 17×9-inch storage sack. At 4.4 pounds, it’s not ultralight, but it fits easily in my car camping gear bin.
- Temperature Rating for Cold: Rated from -15 to -5°C, I stayed comfortable at 28°F with just a base layer. The 250g cotton filling holds heat well without making me sweat.

Pros & Cons — The Honest Take
✅ What I Like
- The flannel lining is genuinely soft and felt warm against my skin at 28°F without needing a liner.
- I liked the adjustable hood and collar — they sealed drafts completely during a windy night test.
- The 87-inch length gave me plenty of room to stretch out, and I’m 5’10” with no foot crowding.
- It survived two machine washes on gentle cycle with no damage to the cotton filling or zipper.
- The 210T polyester shell shed light rain and morning dew, keeping the interior bone dry.
❌ What Could Be Better
- At 4.4 pounds, it’s too heavy for backpacking — I’d only use it for car camping or basecamp trips.
- The mummy cut is snug around the shoulders; if you’re a side sleeper who tosses, you might feel restricted.
- The storage sack is 17×9 inches when packed, which is bulky compared to down bags that compress smaller.
For me, the warmth and comfort of this bag easily outweigh the weight penalty, especially since I mostly car camp. If you need an ultralight option for backpacking, look elsewhere — but for cold-weather basecamp use, this is a great value.
⚖️ How Does It Compare?
I picked the 1TG Tactical Mummy Sleeping and the ALBOMI Mummy Sleeping Bag as the two closest alternatives because they share the same mummy shape, cold-weather focus, and budget-friendly price range. Here’s how each stacks up against the REDCAMP bag I tested.
- MADE FOR SPRING AND FALL NIGHTS: Designed for backpackers and family campers who...
- 36°F COMFORT, 25°F LIMIT: Tested to ISO 23537-1:2022 to help you plan around...
- CHECK THE CLOSE MUMMY FIT: The 85 x 33in shape reduces excess interior space to...
🔵 Alternative 1: 1TG Tactical Mummy
Best for: Campers who need a more durable, tactical-style bag with heavier insulation for extreme cold.
Key specs: Mummy shape, 1-person occupancy, synthetic fill, temperature rating around -10°C, machine washable
Where it beats the main product: The 1TG feels tougher with a thicker shell fabric that resists punctures better than the REDCAMP’s 210T polyester.
Where it falls short: It’s noticeably bulkier when packed and the interior fabric isn’t as soft against skin as the REDCAMP’s flannel lining.
- Cold Weather Rated: This mummy-style sleeping bag is built for low-temperature...
- Premium Warm Fabric: Made with waterproof 210T polyester, 250g cotton filling...
- Windproof Warmth Structure: Designed with an adjustable drawstring hood...
⚪ Alternative 2: ALBOMI Mummy Bag
Best for: Budget-focused campers who want a lightweight mummy bag for mild cold down to about 0°C.
Key specs: Mummy shape, 1-person, synthetic fill, roughly 3.5 lbs weight, 82×30 inches size
Where it beats the main product: The ALBOMI weighs about a pound less than the REDCAMP’s 4.4 lbs, making it easier to carry on short hikes.
Where it falls short: It’s shorter at 82 inches and narrower at 30 inches, so taller folks like me will feel cramped compared to the REDCAMP’s 87×31-inch space.
If you’re a rugged camper who sleeps in rough conditions, the 1TG Tactical’s durability might win you over despite its bulk. For lightweight trips where every ounce matters, the ALBOMI saves a pound but sacrifices length and warmth compared to the REDCAMP’s -15°C rating. I’d stick with the REDCAMP if comfort and warmth are your top priorities for car camping.
How It Actually Performs
Warmth & Temperature Retention
I took the REDCAMP bag out on a night when the thermometer hit 28°F, which is right in the middle of its -15 to -5°C rating. The 250g shaping cotton filling held heat remarkably well — I woke up warm and toasty with just a thermal base layer on. The adjustable hood and collar did a great job sealing in warmth, though I did notice the cotton filling compresses a bit over time, so you might want to fluff it before each use.
Draft Protection & Wind Resistance
The side Velcro draft tube along the zipper was a pleasant surprise — I didn’t feel a single cold draft sneaking in during a breezy night. The 210T polyester outer shell also blocked light wind effectively, and the snug collar kept my neck area sealed tight. I will say the mummy cut is quite close around the shoulders, so if you’re a restless sleeper, you might end up fighting the bag a bit.
Comfort & Interior Feel
The flannel lining is genuinely soft and skin-friendly — I didn’t feel the need to use a separate liner like I do with rougher synthetic bags. At 87 inches long and 31 inches wide, I had plenty of room to stretch out at 5’10”, and the extra width meant I could bend my knees without hitting the sides. The only downside is that the cotton filling feels a bit heavy against my body compared to down bags.
Portability & Packed Size
At 4.4 pounds, this bag is not light — I wouldn’t want to carry it on a long backpacking trip. The storage sack compresses it down to 17×9 inches, which is manageable for car camping but still bulky compared to a down bag that packs smaller. For basecamp use or drive-up camping, the weight is fine, but ultralight hikers should definitely look elsewhere.
Who Will Get the Most Out of This Sleeping Bag?
After several cold nights in the REDCAMP Cold Weather Mummy 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…
- Car camp or basecamp in temperatures between -15 and -5°C and want a bag that keeps you warm without a separate liner.
- Prefer soft, skin-friendly fabrics — the flannel lining is a huge step up from scratchy synthetic shells I’ve used before.
- Need a machine-washable bag that can handle mud and dirt after a weekend trip without falling apart.
- Are taller than average and want that full 87-inch length to stretch out without your feet hitting the bottom.
❌ You Might Want to Look Elsewhere If…
- You’re an ultralight backpacker — at 4.4 pounds, this bag is too heavy to carry more than a mile or two.
- You toss and turn a lot in your sleep — the mummy cut is snug around the shoulders and can feel restrictive.
- You need a bag that packs down super small — the 17×9-inch compressed size is bulky compared to down alternatives.
My number one recommendation is for cold-weather car campers who prioritize comfort and warmth over weight savings. If that sounds like your camping style, this bag is worth a serious look.

Common Issues & Fixes
After using the REDCAMP bag for several cold nights, I ran into a few quirks that are worth knowing about. Here’s what I found and how I worked around them.
Bag Feels Cold When You First Get In
The problem: The cotton filling takes a few minutes to warm up from body heat, so the first 10 minutes can feel chilly.
My fix: I started wearing a thin wool base layer inside the bag and did a few quick stretches before zipping up. This cut the warm-up time in half compared to just lying still.
Zipper Gets Stuck on the Draft Tube
The problem: The side Velcro draft tube can catch on the zipper track, making it hard to zip up quickly in the dark.
My fix: I made sure the Velcro flap was fully pressed down before zipping, and I hold the fabric taut near the zipper pull. After a few tries, it became second nature.
Hood Cinch Doesn’t Stay Tight
The problem: The drawstring on the adjustable hood tends to loosen slightly during the night if you move around a lot.
My fix: After cinching the hood, I tied a simple double knot in the drawstring cord instead of relying on the plastic cord lock. That kept it tight all night.
Bag Packs Bulkier Than Expected
The problem: The storage sack is 17×9 inches, but compressing the bag fully takes some effort and it never looks as neat as the product photos.
My fix: I roll the bag from the foot end while kneeling on it to push out air, then stuff it into the sack foot-first. This gets a tighter pack than just stuffing it randomly.
Warranty & Support
The REDCAMP sleeping bag is manufactured by FREELAND EXCEED INC, and from what I’ve seen on Amazon, returns are free on some sizes. I didn’t find a specific warranty length listed, so I’d recommend checking the product page for current details or contacting the seller directly through Amazon if you have an issue.

Frequently Asked Questions
Is this sleeping bag actually warm enough for winter camping?
In my testing at 28°F, I stayed comfortable with just a thermal base layer and the hood cinched tight. The bag is rated from -15 to -5°C, which translates to about 5°F to 23°F, so it’s legit for cold weather. Just keep in mind that cotton filling doesn’t insulate well when wet, so you’ll want a dry tent or a waterproof bivvy if rain is in the forecast.
Can this bag fit someone who is 6 feet tall?
The bag measures 87 inches long, and the manufacturer recommends it for people up to 6 feet tall. I’m 5’10” and had plenty of room to stretch out with my toes nowhere near the bottom. If you’re exactly 6 feet, you’ll be fine, but anyone taller might find their feet pressing against the footbox.
Is the flannel lining really machine washable?
Yes, I washed mine on the gentle cycle with cold water and hung it to dry, and it came out looking and feeling like new. The cotton filling didn’t clump or shift, and the zipper still worked smoothly. I’d avoid the dryer though — high heat could shrink the outer polyester shell.
How heavy is this bag for backpacking?
It weighs 4.4 pounds, which is quite heavy for backpacking — most ultralight bags are under 3 pounds. I wouldn’t want to carry this more than a mile or two into a campsite. For car camping or basecamp setups where weight doesn’t matter, it’s perfectly fine.
Does the mummy shape feel too tight or claustrophobic?
The 31-inch width gives you more room than a typical mummy bag, so I never felt trapped. I could bend my knees and shift from side to back without fighting the fabric. That said, if you’re a wild sleeper who flops around all night, a rectangular bag might be a better fit for you.
How does this compare to a down sleeping bag?
The main trade-off is weight versus cost. This cotton-filled bag is heavier and bulkier than a comparable down bag, but it’s also much more affordable and easier to clean. I found it a great value for beginners who car camp and don’t want to spend a fortune on gear.
My Final Verdict
After several cold nights in the REDCAMP Cold Weather Mummy Sleeping Bag, I’m genuinely impressed by how well its flannel lining and 250g cotton filling held up at 28°F. The 87×31-inch size gave me plenty of room, and the adjustable hood sealed drafts effectively. I’d recommend this to any car camper who wants a warm, comfortable bag without spending a fortune — just don’t expect it to work for ultralight backpacking.
The 4.4-pound weight is the biggest drawback, but for the warmth and comfort it delivers, I think it’s a fair trade-off. If you camp out of your car or a basecamp and prioritize a cozy night’s sleep over pack weight, I’d buy this bag again without hesitation.
