5 Best 20 Degree Rectangular Sleeping Bags in 2026: A Practical Camping Guide
Best 20 degree rectangular sleeping bags for car campers compared on size, listed weights, fill and zip-together options.
A rectangular 20 degree bag is the easygoing choice for fall and spring car camping: roomy, easy to zip open and cheap to wash. The tradeoff is more air to warm than in a mummy.
Four picks are described as rectangular on their listings, and two Coleman bags with a 20 degree rating are included as nearest fits whose shape the listing does not state. Weights, heights and zip-together options drive the ranking.

Why Each Pick Made the Cut
Best Overall· 1 of 5
Kelty Solstice 20F Degree Oversized Sleeping Bag
Danny’s Take
Wide and well sealed, with room for a pillow and a partner.
Best for
- Roomy car camping for two
Why it made the shortlist
The Kelty Solstice is an oversized rectangular 20 degree bag in recycled 50D polyester pongee, with right-side two-way zippers, an 80 inch shoulder and hip girth and a fit for sleepers up to 6 ft 6 in. The 20 degree version weighs about 6 lb.
It is wider than the Coleman bags and cheaper than the North Face Wawona Bed. A cord at the top cinches closed against the cold, and two Solstice bags zip together for a 2-person setup.
It suits couples and larger campers who want a roomy car bag with a draft tube. Choose the 20 degree version for fall nights.
Key dimensions & specs
- Oversized rectangle, 20F
- 80 in girth, to 6 ft 6
- About 6 lb at 20F
Pros
- Oversized cut with 80 inch girth
- Cinch cord seals the top
- Draft tube and offset quilt construction
- Zips to a second Solstice
Cons
- About 6 lb to carry

Best Brand Quality· 2 of 5
THE NORTH FACE Wawona Bed 20 Sleeping Bag
Danny’s Take
A polished rectangular single with weights and heights printed.
Best for
- Brand-quality rectangle
Why it made the shortlist
The North Face Wawona Bed is a 20 degree F rectangular bag with recycled polyester insulation, a soft taffeta lining and a recycled ripstop shell with a non-PFC DWR finish. The Regular weighs 4 lb 14.3 oz and fits sleepers up to 5 ft 8 in, while the Long weighs 5 lb 4.6 oz and fits up to 6 ft 2 in.
It is lighter than the Kelty Solstice and carries a wraparound footbox zipper that lets the bag open into a blanket. It costs the most of the singles here.
It suits campers who want brand build quality in a rectangular single. Order the Long if you are over 5 ft 8.

Pros

- Shape and size
- Rectangular or oversized cuts, girth and height.

- Listed weights and packed size.
- Zip-together
- Mating zippers and doubles.
- Warmth features

- Cost against included features.
What Matters Before You Choose a 20 Degree Rectangular Sleeping Bag
Key buying criteria so you get the right fit the first time.
Rectangular versus mummy
A rectangle leaves space to move, but that extra air must be warmed by your body. A 20 degree label is often a limit figure, so plan on the comfort range being higher. Use a liner if you sleep cold.
Height and girth
Too short a bag leaves feet against the end and crushes fill. The Kelty Solstice fits to 6 ft 6 in with an 80 inch girth, while the Coleman Brazos stops at 5 ft 11 in. Match both numbers to your frame.
Weight in the car
A 6 lb bag like the Kelty Solstice needs real trunk space. The Wawona Bed lists 4 lb 14.3 oz in Regular. Check weights if space is tight.
Zip-together option
Two compatible bags can zip into a double, which saves money for couples. The Kelty Solstice says two bags zip together. Check the zipper sides match.
Draft control
A zipper draft tube blocks cold at the seam. The Coleman bags list Thermolock tubes and the TETON Mammoth lists zipper and shoulder tubes. Look for a tube on any bag you buy.

Before You Bring One Home
Is 20 degrees warm enough for fall?
For nights near freezing, it is a good start. Plan on the comfort range being warmer than the label. Use a pad and a liner.
Can I use a rectangular bag for backpacking?
They are usually too bulky. The Kelty Solstice 20F Oversized weighs about 6 lb. A mummy is a better choice for trails.
Is the North Face worth the price?
It costs more and the Regular fits only to 5 ft 8, so size matters. The Kelty Solstice 20F Oversized is roomier for less.
How do I zip two bags together?
Pair a right-zip with a left-zip bag of the same line. The Kelty Solstice 20F Oversized says two bags can be zipped together. Test the zip at home.
How do I wash a rectangular bag?
Check the tag, wash in a large machine on gentle and air dry. Do not store compressed. The North Face Wawona Bed 20 has a DWR finish to protect.
