Cold nights are part of the deal. This range covers double sleeping bags for two, a long-cut single for tall adults, a heated sleeping bag, and a USB-powered sleeping bag liner that works inside the bag you already own. All flannel-lined, all rated and sized for real people sleeping in real tents.
Three-season comfort ratings. Compression sacks included. Recover properly, so tomorrow's track doesn't beat you.
Cotton flannel lined sleeping bags, doubles for two people, heated singles and a heated liner. The temperature ratings here separate comfort from limit honestly, so the bag you buy is the bag you sleep in.
Not sure what the numbers mean? Read what comfort, limit and extreme actually mean before you shop. The short version: buy on the comfort rating, not on the name of the bag.
A liner is the cheapest way to add a few degrees to a bag you already own, and it keeps the bag clean. A double avoids the cold seam you get from zipping two singles together. And a bag only performs as well as what is under it, so pair one with an insulated pad or cot.
Flannel-Lined, Every Single One
A flannel sleeping bag feels like bedding. Cheap nylon lining feels like a bin bag, sticks to your skin when you sweat, and goes cold and clammy the moment the temperature drops.
Cotton flannel breathes, so moisture moves away instead of collecting. It stays warm to the touch. And it does not make that plastic rustle every time you roll over, which matters when there are two of you in a tent and one of you is a light sleeper.
This is not a feature on one model. It is the whole range.
Double Sleeping Bags: Two People, One Bag
Zipping two single bags together leaves a cold seam straight down the middle. A purpose-built double sleeping bag does not have one.
We stock two, and they solve different problems:
- FREESPACE 250D. The wide one. Semi-rectangular cut with two built-in pillows, ISO rated, and machine washable when the trip is over. This is the 2 person sleeping bag that makes a roof tent feel like a bedroom.
- 35F 3-Season Double. Two-way separating zippers on both sides, so whoever gets up first does not wake the other one. Unzips flat into a quilt or a mattress topper. Two pillows included.
Both come with compression sacks, because a double that will not pack down is a double you leave at home.
Heated Sleeping Bags: Warmth That Does Not Depend on Fill
Most brands answer cold nights with more insulation, which means a heavier bag and a bigger pack. We answer it with power, because if you camp from a vehicle you already have it.
Two ways in:
- FREESPACE HEATING 250. An extra-wide single with an integrated heating system and three temperature settings, running off a 9V 2A pack. Wide cut, so you are not fighting the bag to roll over.
- 6-Zone Heated Liner. Six zones aimed at shoulders, back, hips and feet, running off USB. It also lies flat on a cot as a heated mat.
Turn it on for the first hour, turn it off when you are warm. That is how you stretch a three-season bag into November without buying a winter bag you will use twice a year.
Sleeping Bag Liners: The Cheapest Way to Extend Your Season
A sleeping bag liner adds warmth to the bag you already own, keeps the inside of it clean, and washes in a machine when the bag itself will not.
Ours goes further than a fabric sleeve: it heats. Cotton flannel face, six heating zones, and it doubles as a cot mat. If you are not ready to replace your bag, this is the upgrade that costs the least and changes the most.
Read the Temperature Rating Properly
Every bag carries three numbers, and the marketing usually shouts the wrong one.
- Comfort. The temperature you will actually sleep well at. This is the number to buy on.
- Limit. Where you stay asleep but curled up.
- Extreme. A survival figure. It is not a camping rating, and no one sleeps at it.
Straight answer: these are three-season bags, with comfort ratings in the high 30s to mid 40s Fahrenheit. They are built for spring through autumn, and for mild winters. If you want to push them colder, that is exactly what the heated liner and the heated bag are for. We would rather tell you the honest range than sell you an extreme number.
Which One Do You Need?
| If you are... | Take |
|---|---|
| Camping as a couple | FREESPACE 250D Double |
| Sharing but on different schedules | 35F Double, dual-side zippers |
| Tall, or sleeping solo | 32F Flannel-Lined, cut long |

| Happy with your bag, just want more season | 6-Zone Heated Liner |
Is This Range Right for You?
Yes, if you camp from a vehicle, you want a bag that feels like bedding, or you sleep next to someone and are tired of the cold seam.
No, if you are counting grams for a backpacking trip, or you need a bag rated for genuine winter mountaineering. These are comfort-first camping bags, and they are heavier than the ultralight alternatives on purpose. Layer them with a camp blanket and they cover most of the year.
Sleeping Bag FAQ
How cold can these sleeping bags handle?
These are three-season bags with comfort ratings in the high 30s to mid 40s Fahrenheit. Spring through autumn, and mild winters. For colder than that, use the heated bag or drop the heated liner inside.
What is the difference between comfort, limit and extreme ratings?
Comfort is where you sleep well, and it is the number to buy on. Limit is where you stay asleep but curled up. Extreme is a survival figure, not a camping rating. Brands quote extreme because it looks better.
Why buy a double sleeping bag instead of zipping two singles together?
No cold seam down the middle. Zipped singles leave a gap exactly where two people meet, and the bags pull apart as you move. A purpose-built double is one piece of insulation, cut wide.
How do heated sleeping bags work?
An integrated heating element runs off a power bank, with adjustable temperature settings. Most people run it for the first hour to warm the bag, then switch it off and let the insulation hold the heat. No stove, no flame, no fuel.
Is the power bank included?
No. The heated bag runs off a compatible 9V 2A pack and the heated liner runs off USB at 5V 2A or 9V 2A. If you camp from a vehicle you probably already have something that works.
What does a sleeping bag liner actually do?
It adds warmth to the bag you already own, keeps the inside of the bag clean, and washes easily when the bag itself does not. Ours also heats, and lies flat on a cot as a heated mat.
Why flannel lining instead of nylon?
Comfort, and it is not a small difference. Cotton flannel breathes, stays warm to the touch, and does not stick to your skin when you sweat. Nylon lining goes clammy and rustles every time you move.
Can I use these for backpacking?
Not really. These are comfort-first camping bags and they are heavier than ultralight alternatives on purpose. They are built for vehicle camping, roof tents and basecamps, where pack weight is not the constraint.
