Best Rectangular Sleeping Bag
We explored and tested the most popular rectangular sleeping bags in the market to determine the best ones in terms of comfort, features, and pricing. Our top picks are as follows:
Affordable sleeping bags does not mean subpar protection. The Teton Sports Celsius provides bang for your buck if you are looking for a rectangular sleeping bag that can withstand cold conditions.
For less than $100, you get a unique sleeping gear that combines the best of the mummy-style bag and a rectangular sleeping bag. The hood connects to the body, which provides comfortable protection against the cold. The 0-degree temperature rating is quite surprising for a bag this affordable.
However, it does cut some corners in order to lower the price point. The zipper is a bit finicky to use. Additionally, the polyester filling is not as easy to pack down as other sleeping bags. However, Teton Sports is a great value for money, especially if you are expecting cold conditions during your trip.
Teton Sports Polara 3-in-1 comes very close the being the best rectangular sleeping bag around. Its versatile construction makes it a great fit for most weather conditions. It features multiple removable layers so you can achieve the perfect comfort and protection during your adventures.
It provides up to five single-person configurations and two double-wide layouts. This makes the Teton Sports Polara one of, if not the most, adaptable sleeping bags in the market. It also includes pockets, drawstrings, snaps, loops, and a detachable fleece liner.
However, no sleeping gear is perfect. To achieve its reasonable price, the manufacturer skimped a bit on the materials, which may feel too synthetic at times. The interior liner is grabby at times which can be mildly annoying.
North Face is a popular outdoor brand that produces top-notch products. And, the Eco Trail Bed 20 is one of its top-performing rectangular sleeping bags. For about a little over $100, you get a comforter-like sleeping bag that you can bring during your camping trips.
With a temperature rating of 20 degrees Fahrenheit, it is perfect for three-season car camping in a variety of conditions. That means the sleeping bag can withstand close to freezing conditions. It also has a premium feel and construction, along with a full-length zipper that opens it up for use as a blanket.
Remember that rectangular bags are relatively heavier than mummy options. The former does not pack as well as the latter, especially if you are going on long backpacking trips. But, it is a trade-off for premium comfort, flexibility, and spacious interior.
The Eco Trail line replaces the old Dolomite line with the goal of improving key features. The Eco Trail Bed 20 uses 100% recycled materials. It is also relatively lighter than the old line at 4 lbs. 8 oz.
Sleeping bags are considered an investment for any camper. However, if you are only looking for the most affordable option, then the Coleman Green Valley is a decent option. It gets the job done if you prioritize price above all else.
Its flannel lining and slick nylon exterior are enough to provide warmth and comfort during most nights. At a temperature rating between 30 to 50 degrees, it is suitable for camping nights during summer or spring. However, you may need an extra layer at the lower end of that range.
At this price point, you cannot expect a premium feel. But, the basic construction and quality are a great value for the price. It is a great back-up sleeping bag without shelling out a lot.
The Coleman Brazos is another low-priced sleeping bag that is great for casual campers. If you are not looking for anything premium, then the basic features of Brazos will get the job done. At sub-$50 pricing, it is quite a steal compared to other cheap options.
At around 75 inches long and 33 inches wide, it may feel a bit cramped of anyone taller than 5’11” or those with a wider body type. However, it is surprisingly warm for casual outings during late spring or summer nights.
Additionally, it is durable enough to withstand abuse. Combined with its narrow design and inexpensive price point, it is a great option for kids and teens. There’s no need to worry about ruining premium sleeping bags anymore.
Finding a rectangular sleeping bag made of down is quite difficult as many manufacturers prefer synthetic insulation. However, the Kelty Galactic 30 combines these two features to create a sleeping bag that provides great comfort. As such, the lofty down clusters provide a premium feel and protection, which are not found in polyesters.
The camping sleeping bag still takes advantage of polyester material which protects its outer layers. Additionally, the DriDown insulation has a hydrophobic finish which prevents moisture from seeping in. That means it can keep you warm even during relatively wet climates.
However, its decent 30-degree Fahrenheit temperature rating means it’s not suitable for cold weather conditions. Additionally, the down filling is difficult to dry if the sleeping bag gets soaked.
If you are a stomach or a side sleeper, it can be tricky to look for backpacking sleeping bags or camping gear. Fortunately, the unique design of the Sierra Designs Frontcountry Bed provides comfort without compromising your sleeping position.
The distinctive design can be likened to a pea pod. While the rectangular sleeping bag does not have any zippers, the big opening at the top is more than enough to slide in comfortably. It also comes with a built-in comforter for extra warmth.
The large insulated zone above your head fits a standard-sized pillow. It also accommodates your elbows well. The special pockets for your hands are nifty if you want to sleep untucked.
Its synthetic insulation is a standard for a sleeping bag for camping. However, some users may find it a bit too open, especially during cold conditions. The 20-degree Fahrenheit temperature rating is enough to keep you warm and comfortable for most nights.
The Kelty Tru.Comfort 20 Doublewide is a favorite among couples who love camping together, and for good reasons. Unlike other two-person models that just provide extra fabric, this rectangular sleeping bag provides a decent sleeping system that is comfortable.
It comes with built-in blankets for each sleeper which provide options for warmth and protection. The massive hood helps pillows stay in place. Additionally, it also traps heat, especially during cold weather conditions.
The foot box features a U-shaped, top-side zipper that allows toes to stay warm. The Tru.Comfort is made of high-quality taffeta fabric, which feels ultra-soft and silky. However, it is prone to snags and tiny tears. That means a sleeping pad is necessary to protect the sleeping bag.
The Alps OutdoorZ Redwood is a favorite among campers due to its sleek design and super-rugged construction. It also boasts a soft and ultra-comfortable interior. Many fans of the rectangular sleeping back say it feels like a weighted blanket when they slip inside.
The durable canvas exterior combined with a cotton flannel liner makes it one of the most luxurious options in the market.
However, the Redwood also had drawbacks. First, it packs a bit bulky, which makes it unsuitable if you have limited space in your bag. Additionally, the cotton material traps water which is not the best if you are expecting wet weather conditions.
While it may not protect you well during extreme climates, it is a great sleeping bag for casual travelers. If you are on the lookout for comfortable and luxurious sleeping gear, then the Alps Outdoorz Redwood is a great go-to option.
If you always travel with someone, you may encounter the dilemma of choosing between two individual sleeping bags or one two-person sleeping bag. With the Alps Mountaineering Spectrum 20, you do not have to choose between the two.
The versatile rectangular sleeping bag snugly sleeps two people. However, you can easily convert it into two individual bags if you want to sleep solo. You can even open it up and use it as a quilt. During warm nights, you can sleep on top of both layers, which feels like your own bed at home.
With its soft-touch fabric along with the 20-degree temperature rating, the sleeping bag is more than enough for most of your adventures. However, it is one of the heaviest on this list at 12 pounds because it accommodates two. As such, it is more suitable for casual or car camping.
Camping is a bit more casual and relaxed compared to backpacking. However, an uncomfortable night can ruin an entire trip. Here are a couple of things that you need to consider when shopping for the best sleeping bag for camping.
Rectangular vs. Mummy
Most sleeping bags fall under two categories — rectangular bags that give plenty of space to roll around and cozy mummy bags. Many campers prefer the wider rectangular shape. Most of these flexible bags can also be fully unzipped down one side and at the bottom, so they can be used as a large blanket for two.
Rectangular bags are popular among casual campers due to their versatility. However, most do not include insulation over your head. So, plan your sleepwear, especially during chilly nights.
Rectangular sleeping bags are designed to provide ultimate comfort while protecting you from the cold. As such, most are relatively heavy and don’t pack down small. They are more suitable for car camping or a fun outdoor trip.
On the other hand, mummy-style sleeping bags are more popular among the backpacking crowd. They have trimmed the materials in the shoulders, hips, and legs to create a form that mimics the body. Due to this, they have better packability which is great for solo trips where every ounce counts.
The benefit of having a tapered cut there is little to no space for cold spots to seep in. The built-in hood cinched over the top of your head optimizes your ability to retain heat.
If you’re at higher elevations or cooler climates, a mummy bag is a perfect choice.
Most manufacturers use two types of insulation fill: down and synthetic. The former is made up of clusters of duck or goose feathers which provides a natural comfort feel.
It provides the best warmth-to-weight ratio along with outstanding packability, which is why most backpackers prefer this type of insulation. However, due to the limited supply of organic fill, down is much more expensive.
Meanwhile, weight and packability are usually not major considerations when camping. With a car or camper to accommodate all of your stuff, the bigger stuffed size and excess weight is much less of a problem.
As such, synthetic fill is mostly used in most rectangular sleeping bags due to their practicality and affordability. And should the insulation get damp, synthetics keep you warm, unlike down feathers.
However, some rectangular sleeping bags come with down fills. While pricier, these bags combine the ultimate comfort of a natural fill with a roomier design.
It is important to note that temperature ratings for sleeping bags do not follow a standard grading system, such as EN rating, unlike backpacking bags. Instead, manufacturers assign scores to their camping bags. So, do not treat these ratings as absolute truths.
Once you get them out in the real world, there are several major differences in performance. This is mostly due to the shape of a lot of camping bags. A rectangular bag with a large opening on one end cannot hold heat in the same manner that a sealed mummy bag would.
However, the temperature rating is still a useful guideline in picking the best rectangular sleeping bag. First, try to get an idea of the coldest temperature that you are expecting during your trip. Then, create a buffer of about 10 to 15 degrees Fahrenheit.
In any case, most campers stick to warmer months. If you love going on trips during colder seasons, explore backpacking bags instead.
Generally speaking, camping is much simpler than backpacking. That means you do not need all extra features to have a comfortable night’s sleep.
You can purchase a decent rectangular sleeping bag for under $100. If your budget allows it, spend extra bucks for smother shell fabric or a down filling.
However, if you want sleeping gear that gets the job done, you will be fine with a generous synthetic filling, a rugged nylon shell, and a cotton flannel liner.
A Few Reminders
Take note of the zipper construction of your bag of choice. Typically, you want a rectangular sleeping bag that totally unzips. You can zip it into another bag to create a cozy room for two. And, if the exterior is made of tough fabric, it will make a great outdoor picnic blanket.
Another consideration is choosing a double sleeping bag. If you are going on a trip with a partner, it can be a cheaper option than purchasing two single sleepers. Of course, doubles bags are much heavier and bulkier, so keep that in mind as well.
Don’t forget to bring a durable sleeping pad as well. A nice insulated pad will significantly improve your experience, especially on a cold night.
Camping provides a bit of wiggle room in terms of weight. As such, comfort becomes a considerable priority, especially if you want a great sleep outdoor. Of course, you need to keep temperature ratings in mind, especially if you expect cold weather conditions.
With that said, we love both rectangular sleeping bags from Teton due to their excellent temperature rating. And at reasonable pricing, these two bags are great options for all-around sleeping gear for campers.
While Teton Sports Celsius‘s exterior gets the job done keeping moisture away. It combines the best features of mummy bags and rectangular bags to create a comfortable sleeping experience.
We love the versatility of Teton Sports Polara 3-in-1. It can adapt to different types of comfort levels along with all the extra features. More than a solo sleeping bag, it can turn into a double bag and provide comfort for both individuals.
Just like any gear, your top pick should come with features that are relevant to your needs. Prioritize comfort, temperature rating, pricing, and other factors to guide you during shopping.
