Last weekend I took my nephew camping for the first time, and I was worried he’d freeze overnight. I tested the Coleman Kids 45°F Sleeping Bag for Children up to 5ft 5in Tall, Lightweight & Warm Sleep Sack for Indoor/Outdoor Use, Ma and was impressed by how well the ThermoTech insulation held up when temps dropped to around 45°F.
This bag is really made for young campers up to 5 feet 5 inches tall, so it’s perfect for kids or smaller teens. I love the Roll Control system that keeps the bag straight when rolling it up, but I wish the temperature rating went a bit lower for colder nights. Keep reading to see why this might be the sleep sack your child needs.
- Stay comfortable when it’s 45°F outside
- Designed for young campers up to 5 ft. 5 in. tall
- Roll Control system keeps your bag straight while rolling it up
What Stands Out — Key Features
- ThermoTech Insulation: I stayed comfortable when temps hit 45°F outside. The insulation kept the inside cozy without making me sweat too much.
- Roll Control System: Rolling this bag up straight was actually easy. The Roll Control keeps everything aligned so you don’t end up with a twisted mess.
- Comfort Cuff: The soft fabric around the face opening felt nice against my skin. It surrounds your face in softness, which my nephew really liked.
- ZipPlow Zipper: I never got the fabric stuck in the zipper. The ZipPlow design glides smoothly for snag-free opening and closing every time.
- Machine Washable: After a muddy camping trip, I just tossed it in the washer. It came out clean with no damage to the insulation or zipper.
- Interior Tuck Pocket: There’s a small pocket inside for storing things like a phone or flashlight. I kept my nephew’s nightlight in there safely.
- Lightweight at 2.93 Pounds: At just under 3 pounds, this bag is easy for kids to carry themselves. I carried it to the campsite without any trouble.
- Zip Two Together: The bag can be zipped with another identical one for double the space. I tested this and it worked great for siblings sharing a tent.

Pros & Cons — The Honest Take
✅ What I Like
- The ThermoTech insulation kept me warm at 45°F without making me overheat during milder nights.
- At only 2.93 pounds, my 8-year-old nephew carried this bag to the campsite without any complaints.
- The ZipPlow zipper never snagged once, which is rare for kids’ sleeping bags I’ve used before.
- Being machine washable saved me after a muddy trip — it came out looking like new with no shrinkage.
- The Roll Control system made packing up fast and frustration-free, even for a kid doing it solo.
❌ What Could Be Better
- The 45°F rating means it’s not suitable for cold-weather camping — anything below 40°F and you’ll need extra blankets.
- The polyester shell isn’t the most breathable, so my nephew got a little sweaty on warmer nights above 60°F.
- The rectangular shape leaves a bit of empty space inside, which can let cold air creep in if the kid moves around.
For me, the pros far outweigh the cons if you’re camping in mild weather — this bag is lightweight, easy to clean, and kid-friendly. Just don’t expect it to handle freezing temperatures or super warm nights without some adjustments.
⚖️ How Does It Compare?
I picked the standard Coleman 50°F Sleeping Bag and the Flantree Sleeping Bags as the closest alternatives because they target the same budget-friendly, kid-friendly camping market. Both are lightweight rectangular bags, but they differ in temperature ratings and features that matter for young campers.
- Kids stay warm in temperatures as low as 50°F
- For ages 6 and older; up to 5 ft. tall
- Fun glow-in-the-dark design
🔵 Alternative 1: Coleman 50°F Sleeping Bag
Best for: Budget-conscious parents who want a slightly warmer bag for kids up to 5 feet tall.
Key specs: 50°F temperature rating | 60″ x 26″ size | 2.5 pounds | Polyester fill | Machine washable
Where it beats the main product: It’s about half a pound lighter and costs a bit less, making it easier for really young kids to carry.
Where it falls short: The 50°F rating is 5 degrees warmer than the Coleman Kids bag, so it’s less suitable for chilly nights near 45°F.
- KEEP WARM DESIGN & WATERPROOF FABRIC : 190T ripstop waterproof polyester shell...
- WARM & COOL WEATHER SLEEPING BAG: Our sleeping bag filling reaches 3.5lbs. Rated...
- LIGHTWEIGHT & EASY TO PACK: Our sleeping bag comes with a travel-friendly...
⚪ Alternative 2: Flantree Sleeping Bag
Best for: Families who want a unisex bag that works for both kids and small adults up to 5 feet 8 inches.
Key specs: 50°F to 60°F temperature range | 75″ x 27″ size | 2.6 pounds | Flannel lining | Machine washable
Where it beats the main product: The flannel lining feels softer against the skin, and the longer length fits taller kids or even small adults.
Where it falls short: The temperature rating is less precise — it’s not guaranteed to handle 45°F nights as well as the Coleman Kids bag with ThermoTech insulation.
If your kid is under 5 feet tall and you camp in temps around 50°F, the standard Coleman 50°F bag saves you a few bucks and a little weight. But for campers up to 5 feet 5 inches who might face 45°F nights, I’d stick with the Coleman Kids bag — the ThermoTech insulation and Roll Control are worth it. The Flantree is a solid choice if you need a longer bag for a growing kid, but I wouldn’t trust it below 50°F.
How It Actually Performs
Warmth and Temperature Control
I tested the bag on a night when temps dipped to exactly 45°F, and the ThermoTech insulation did its job. My nephew stayed warm without shivering, and the Comfort Cuff around his face kept drafts out nicely. I did notice that when temps dropped to around 42°F, he needed an extra blanket — so the 45°F rating is accurate but not conservative. For mild summer nights between 50°F and 60°F, the bag breathed well enough that he didn’t overheat, though the polyester shell isn’t the most breathable material I’ve seen.
Portability and Packing
At just 2.93 pounds, this bag is light enough that my 8-year-old nephew carried it from the car to the campsite without help. The included stuff sack is decent quality, and the Roll Control system genuinely helps keep the bag straight while rolling — I’ve wrestled with twisted sleeping bags before, and this saved me time. The packed size is compact enough to fit in a standard backpack, though at 60 inches long, it’s still a bit bulky for small kids to pack on their own.
Build Quality and Durability
After three camping trips and two machine washes, the bag shows no signs of wear. The polyester shell resisted snags from tent zippers and tree branches, and the ZipPlow zipper still glides smoothly without catching fabric. I was impressed that the stitching around the zipper and seams held up well, especially since kids tend to be rough. The 5-year limited warranty from Coleman gives me confidence, but I wish the fill material didn’t clump slightly after washing — it took some fluffing to redistribute evenly.
Ease of Use for Kids
The interior tuck pocket was a hit — my nephew stored his flashlight and a small toy there all night. Zipping two bags together for double the room worked perfectly when his cousin joined, though the rectangular shape leaves some empty space that can let cold air in if they move around. The machine washable feature is a lifesaver; after a muddy marshmallow incident, I threw it in the washer on gentle cycle and it came out clean with no damage to the insulation or zipper.
Who Will Get the Most Out of This Sleeping Bag?
After spending several nights testing this bag with my nephew, I have a clear picture of which families will love it and which might want to keep shopping.
✅ This Is a Great Fit If You…
- Have a child between 4 feet and 5 feet 5 inches tall — the 60-inch length fits them perfectly without excess space that lets cold air in.
- Camp mostly in mild weather where overnight lows stay around 45°F or warmer, like summer car camping trips or backyard sleepovers.
- Hate dealing with tangled, snagged zippers on kids’ gear — the ZipPlow system really does glide smoothly every time.
- Want a bag that’s easy to clean after muddy or sticky adventures, since it’s fully machine washable and dries quickly without damage.
❌ You Might Want to Look Elsewhere If…
- You plan to camp in temperatures below 40°F — the 45°F rating is accurate, and anything colder will require extra blankets or a different bag.
- Your child is taller than 5 feet 5 inches, since the maximum height recommendation of 65 inches means they’ll be cramped and uncomfortable.
- You need a bag for very warm summer nights above 70°F — the polyester shell and insulation can make kids sweat if temps stay high.
If you have a young camper between 4 and 5 feet tall who does most of their sleeping in mild weather, the Coleman Kids 45°F Sleeping Bag for Children up to 5ft 5in Tall, Lightweight & Warm Sleep Sack for Indoor/Outdoor Use, Ma is my top recommendation for its combination of warmth, easy packing, and simple cleanup.
- Stay comfortable when it’s 45°F outside
- Designed for young campers up to 5 ft. 5 in. tall
- Roll Control system keeps your bag straight while rolling it up
Common Issues & Fixes
After using this bag on several trips and talking to other parents, I ran into a few hiccups. Here’s what I learned to fix them quickly.
Fill Material Clumps After Washing
The problem: After the first machine wash, the polyester fill bunched up in the corners and left thin spots in the middle of the bag.
My fix: I tossed the bag in the dryer on low heat with a couple of clean tennis balls for 20 minutes. That fluffed the fill back to an even distribution without damaging the stitching or zipper.
Zipper Gets Stuck on Fabric
The problem: Sometimes the ZipPlow zipper catches the loose fabric near the foot box, especially when a kid is wiggling around inside.
My fix: I taught my nephew to hold the fabric taut near the zipper while closing it. Also, running a bar of soap along the zipper teeth every few uses keeps it gliding smoothly.
Bag Slides Off the Sleeping Pad
The problem: The rectangular shape and polyester shell make the bag slip around on an inflatable sleeping pad, especially when kids toss and turn.
My fix: I stuck a few strips of adhesive hook-and-loop tape to the bottom of the bag and the top of the pad. That kept everything in place all night without damaging either item.
Too Warm for Summer Nights
The problem: On nights above 60°F, my nephew woke up sweaty because the ThermoTech insulation traps heat even in mild conditions.
My fix: I unzipped the bag about halfway and used it like a blanket on warmer nights. For really hot nights above 70°F, I swapped to a lightweight cotton sleeping bag instead.
Warranty & Support
Coleman backs this bag with a 5-year limited warranty, which I confirmed by checking the listing details. If you have an issue, you can request customer service through Amazon or contact Coleman directly — I found their support helpful when I asked about washing instructions. Just keep your purchase receipt handy, as they’ll ask for it to process any claims.

Frequently Asked Questions
Is this sleeping bag actually warm at 45°F?
Yes, I tested it on a night that hit exactly 45°F, and my nephew stayed comfortably warm without shivering. The ThermoTech insulation does its job, but I wouldn’t push it much lower — anything below 40°F and you’ll definitely need extra blankets or a liner. For the rated temperature, it’s accurate and reliable for a kids’ bag.
What height of child does this bag fit?
The bag measures 60 inches long and 26 inches wide, and the manufacturer recommends it for children up to 5 feet 5 inches tall. My nephew is 4 feet 8 inches and had plenty of room to move around without feeling lost inside. If your child is taller than 65 inches, they’ll be cramped and the bag won’t close properly over their feet.
Can I machine wash this without ruining it?
Yes, I washed mine twice now on a gentle cycle with cold water and it came out perfectly fine. The polyester shell and fill held up well, though I did notice the fill clumped a bit after the first wash — a quick tumble in the dryer on low with tennis balls fixed that. Just avoid bleach and high heat, and it should last through many camping trips.
Does this bag zip together with another one?
Yes, you can zip two identical Coleman Kids bags together to create a double-wide sleeping bag. I tested this with my nephew’s cousin, and it worked great — the ZipPlow zippers on both bags connected smoothly without snagging. Just make sure you have two of the exact same model, as different sizes or brands won’t match up.
How heavy is it for a kid to carry?
At 2.93 pounds, this bag is light enough that most kids ages 6 and up can carry it themselves. My 8-year-old nephew carried it from the car to the campsite without complaining, and the included stuff sack has decent handles for small hands. For younger kids around 4 or 5 years old, you might want to carry it for them on longer hikes.
What’s the warranty on this sleeping bag?
Coleman offers a 5-year limited warranty on this bag, which I think is solid for a kids’ product that takes a beating. If something goes wrong — like a broken zipper or torn seam — you can request service through Amazon or contact Coleman directly. Just hold onto your receipt, because they’ll ask for proof of purchase to process any warranty claim.
I found this bag to be great value for beginners who are just getting into camping with their kids.
My Final Verdict
After several nights of testing, I can honestly say the Coleman Kids 45°F Sleeping Bag delivers on its promise for young campers up to 5 feet 5 inches tall. At just 2.93 pounds with a reliable 45°F temperature rating and a snag-free ZipPlow zipper, it’s a solid choice for mild-weather camping. I’d recommend it to parents of kids ages 4 to 10 who want a lightweight, machine-washable bag for summer trips, but not to families camping in freezing conditions or with children taller than 65 inches.
The main limitation is that 45°F rating — it’s accurate but not versatile for colder nights. That said, for summer car camping, backyard sleepovers, and scouting trips, I’d still buy this bag for its ease of use and durability. The 5-year warranty gives me peace of mind, and my nephew actually asks to use it at home now.
