18 Best Sleeping Bags in 2023 | For Winter & Summer

Wrapping yourself in a cozy blanket in the middle of the forest has never been as dreamy as it is with Marmot’s 3-season Phase 20F Degree Down sleeping bag. Built from the durable Ripstop Nylon of 10 deniers, this model has been appreciated by backpackers and campers alike. Cold and damp weather isn’t an obstacle to avoid – rather, it is the fact to accept thanks to the water-resistant construction of the down.

Not only will you feel warm and snug in the anatomical foot box that provides your feet with the desired comfort, but you will also have sweet dreams due to the sleeping bag’s mellow and feathery goose filling. The manufacturer ensured the no heat is ever lost by incorporating curved baffles across the bag and the hood into the bag.

If feeling lonely, you can always take your phone and headphones with you in the sleeping bag – once you are ready to fall asleep, stuff them in the internal stash pocket and you are good to go (read: sleep).

The Spark Ultralight 28F is one of Sea to Summit’s backpacking sleeping bags. It’s a feature-rich bag intended for autumn, winter and spring camping. In particular, mountain campers will be interested in this sleeping option for its packability and ultradry properties.

This bag has a mummy style shape with a draw-string hood enclosing the body. Available in regular and long, they’re pretty true to size while allowing for a little extra wiggle room. That’s intended for use with extra clothing or the Spark liner when approaching the freezing point.

We tested the regular, designed for a max height of 6 feet. Our tester stands at 5’11, 198 lbs. and went camping at temperatures ranging from 30℉ to 50℉. That will be the reference for this review.

Thinking if Sea to Summit got the sleeping bag you’re looking for? Want an outdoor bed ready to give you a restful sleep during your adventures in the wild? Spark Ultralight might put an end to your search.

It’s a lightweight and super packable model with robust construction. Spark’s 850+ loft goose down provides excellent insulation even in environs as cold as 28oF. This outdoor bed from Sea to Summit also has a mummy cut for a cozy fit. But, there’s also enough room inside for some movement.

The high price might shoo some people away, and it’s not a perfect sleeping bag. It can’t please everyone’s preferences.

But for those who find Sea to Summit Spark Ultralight appealing, the value you get for your invested money is worth it.

Here’s a closer look at what this outdoor bed has to offer.

From short to regular and long, The Kelty Cosmic 20 Degree Down sleeping bag has got you covered down to 9°F. Including short, regular and long sizes this budget-friendly model is a reliable choice.

Insulated with 600-fill DriDown and equipped with the best insulation possible, this sleeping bag is a catch. It has got a Polyester Taffeta lining that is soft on the touch and warm enough to provide you with the non-chilly 8-hour night sleep. Features like the draft collar and a warm jacket-like hood ensure the absence of cold, while the dual-sliding zipper of 60 inches guarantees the worry-less night.

Make use of the electronic pocket located on the outer part of the sleeping bag and the stuff sack that comes with the sleeping bag.

A dependable sleeping bag has a special place in the heart of anyone who spends more than a handful of nights outside each year. Sea to Summit’s Ascent series sleeping bags are versatile and feature-rich 3-4 season options for those of us keeping it below treeline in the winter.

The series has 3 bags, each rated for different temperatures: Ac1 (25℉), Ac2 (15℉) and Ac3 (0℉).

I had the chance to try out their 25ºF Ac1 with the Thermolite Retractor liner and feel the system is an excellent all-condition option that I’d be happy to call home on most any adventure.

Mild winter, spring and fall can all be survived with the Coleman Green Valley Cool Weather sleeping bag. It is able to accommodate temperatures from 30 to 50 degrees Fahrenheit and fit most heights up to 5’11 inches. Unlike other sleeping bags, this model is not a cocoon-like container that is reminiscent of an insulated tube.

Instead, it looks like a single bed mattress that is made from plush material that keeps you warm all through the night. Its fiber-lock construction doesn’t allow the insulation to shift, which means that you will be using this bag for years with no reduction in its functionality. The practicality of the sleeping bag is uncanny – its zipper has a no-snag feature that makes it quick and easy to fasten and unfasten the bag with no fabric coming in the way.

Moreover, the Thermolock system integrated into the sleeping bag helps to reduce the loss of the heat through zippers. What this means for you is the long night sleep with no freezing whatsoever.

The spoon-shaped sleeping bag from Nemo can make a great companion for weekend camping as well as a week-long backpacking trip. Recognized as a ‘mummy’ bag, it involves more room for knees and elbows that we all need for comfortable sleep. This medium-price-range camping equipment is made with the PVC-free down that is water-resistant.

The waterproof panel located on top of the toe area provides additional protection against wet weather conditions which are so often met in the woods. As the heat tends to come from the limbs, this feature is particularly handy for keeping your feet warm at all times.

There are two zippered ThermoGrills on both sides of the bag that ventilate the body well enough without allowing the cold air to flow in. You can either unzip the vents down to cool off or zip them up for the warm night of insulation. The practice proves that it is indeed nice to have options.

The Vango Nitestar 350 sleeping bag is the adventure-friendly piece of outdoor equipment that won’t break the bank. It is built from the sturdy Polyester and has warm double-layer insulation to keep you cozy all night long. This ‘mommy’ bag looks like a guitar case, but instead of a box shape that keeps the guitar in, the sleeping bag uses its tube-shaped material to trap the warm air in and not allow the cold to come through.

The bag is constructed in a way to eliminate the cold spots from the stitch lines to provide you with the utmost comfort. The zip baffle together with the main two-way lock zip seals the heat even more. You can easily hang your Vango sleeping bag to dry thanks to the loops attached to it.

The manufacturer took it a step further and added grabbing loops for you to be able to transport the bag from A to B without getting easily exhausted.

The Western Mountaineering HighLite sleeping bag is the definition of class and comfort that come at a steeper price. At the mere 1 pound, this sleeping bag is one of the most lightweight bags on the market. This California-based brand has been producing high-end sleeping bags for years now and didn’t disappoint with this model either.

The 850-fill down insulation is there, and so is the water-resistant coating designed to protect you from the unforeseen weather fluctuations. The sleeping bag takes pride in its ultra-breathable ExtremeLite shell that has a high thread count and a good rate of warmth.

There is no way the warm air will escape the sleeping bag – the horizontal seams are well-sewn into the fabric, while the waist and shoulder girth remove the pockets of dead air for your comfort.

If a snug mummy bag is not your cup of tea, a roomy rectangular sleeping bag like the one from TETON Sports will certainly meet your requirements. The Celcius is a steal from every perspective – it is warm due to the brushed poly-flannel liner, has a mummy-style hood and can be tucked into a stuff sack with heavy-duty compression straps.

It is indeed great to come back after a long day of hiking and fall asleep in a roomy sleeping bag that can be unzipped from either side. The anti-snag zippers can be smoothly rolled up and down when you are getting up, while the interior pocket is in charge of keeping your valuables safe during the entire night.

The manufacturer took care of the smallest details and added draft tubes around the shoulders to keep the drafts out along with the double-layer offset stitching and a hollow fiber for that warmth.

If sleeping in a cloud sounds exciting to you, the Sierra Designs Cloud 20 sleeping bag is right up your alley. This no-zip gear is a game-changer for those of you who cannot bother zipping up or down your sleeping bag while still wanting to remain warm.

The 800 DriDown fill combined with the 15-Denier Nylon Ripstop provides you with the coziest hiking tool that will keep you warm even when the temperature reaches 15 degrees Fahrenheit. The Cloud has a self-sealing foot vent that allows you to kick your feet out if some fresh breeze is needed.

Furthermore, whenever you get too hot, you can twist the sleeping bag in a way that enables you to bring your arms out. With the sleeping pad integrated into the bag, you are bound to sleep like a baby through the night.

The Nemo Forte sleeping bag is created specifically for those who sleep on their side and turn around all night long. Thanks to the spoon-like design, this item has enough space at the elbows and the knees for you to change your sleeping positions during the night.

As if the side sleepers-friendly shape wasn’t sufficient, the manufacturer introduced a BlanketFold – a feature that allows you to tuck yourself in like you would if you were sleeping back at home. The PrimaLoft RISe insulation contributes to the warm night of sleep, while the Nylon shell protects the sleeping bag from getting wet when the weather turns its back on you.

If worried about getting too hot, there is a ThermoGrill attribute that is able to extend the temperature range of your gear on milder nights – simply unzip the bag and let the hot air out without getting cold.

The Trestles Elite Eco 30 is a well-made, eco-friendly bag designed for women. It also has some waterproofing. We like this Marmot bag for its packability as much as its warmth and coziness outside on a crag with a cup of coffee in the morning.

Featuring HL-ElixR Eco fill, the sleeping bag retains the warmth of goose down using recycled, synthetic fibers instead. The wave design of the bag provides you with maximum warmth from top to bottom as part of a wise sleeping system.

As for packability, the included compression sack makes the Trestles 30 shrink down in volume for backpacking joy.

This sleeping system has been called by customers ‘fabulous’ and we couldn’t agree more. The Big Agnes Buffalo Park sleeping bag is a semi-rectangular camping gear you didn’t know you needed for more than a good night of sleep. It is wide enough to give you sufficient space for moving around at night while also keeping you warm and cozy due to the Thermolite polyester fill.

The full pad sleeve works well in accommodating pads of all thicknesses, whereas the pillow barn helps to keep your pillow in place all through the night. Your new backcountry bed is built from the sturdy Nylon Taffetta that ensures the longevity of the gear.

It also contributes to the double zippers not sticking to the shell when zipping up and down. Utilize the top corner of the sleeping bag to wrap it around your shoulders and you are good to go (read=sleep).

This feature-rich rectangular sleeping bag by Kelty is named Galactic for a reason – you will stay warm enough to be able to see the dimmest stars in the sky with it in use. Whether you choose a faraway hiking trail or a 30-minute away from the city camping site, you will be safe and sound with this water-resistant down designed to provide you with the warmest insulation ever.

Unlike somewhat restricting mummy bags, this model doesn’t make you feel constrained when sleeping. It has got anti-snag zippers that allow you to quickly enter and exit your sleeping bag as well as bring your feet or arms out when it gets too hot. You can even zip this sleeping bag together with the second bag to create a cozy bed for 2 people. P.S.:

Although the bag has a natural down fill, it is RDS-certified, meaning no animal cruelty was involved in its creation. It’s good to know you’re not contributing to the already saturated market of products made from materials implicating animal abuse.

The LEEF mummy-style sleeping bag released by TETON Sports is the optimum hiking solution for every outdoor enthusiast out there. It has got the qualities of a high-end sleeping bag and the price of an affordable gear that will last you many years. No matter if you choose the 20-degree temperature limit or the 0-degree one, you will stay warm and dry throughout the entire night.

The 40-denier water-resistant Ripstop Nylon along with the brushed PolyFlannel and the PolarLite insulation provides you with warmth like no other. There is the mummy hood for you to cinch down before falling asleep and the taped anti-snag zippers for you to self-ventilate when desired.

No strangers or wild animals will steal your valuables – you can store them in the internal sleeping bag pocket that will keep them safe.

The Nemo Jazz 20-degree sleeping bag is the crystal clear explanation of the phrase ‘sharing is caring’. We mean, can it get any more selfless than this? Probably not. Just like the comforter, this sleeping bag has two zippers on both sides to make it easy for you and your partner to enter and exit the gear in an instant. Although it is designed for two people, you can easily fit kids under 6 with you and have a snuggle party before going to sleep.

The Stratofiber insulation backed by the water-resistant Ripstop Nylon shell equips you with the warmth of a real bed and the comfort of a blanket. The integrated bed sheet can be removed when it’s warm outside, while the pillow-top quilt protects your head from getting cold during the night. The tapered design allows your legs and arms to stay warm and safe by removing the excess airspace.

Bring it to your next family recreational adventure in the woods and you will appreciate the premium features of the sleeping bag yourself.

This Amazon bestseller has quickly caught your attention for a variety of reasons. Starting with its envelope/mummy shapes that are just the right size to comfortable sleep in and finishing with the risk-free satisfaction guarantee from the manufacturer, the sleeping bag by VERZEY is a gem.

Coming at roughly $38, it is built from the highest quality Dacron that makes the gear’s affordability laughable. Covered with a waterproof coating, there is nothing this sleeping bag won’t be able to withstand. Be it rain or thick fog, you can cozy up in your new hiking essential and sleep all through the night.

The half-moon hood has a drawstring that can be adjusted to fit your face well and the velcro tab keeps the zipper from opening. There is even a small inside pocket for storing your smartphone along with earbuds.

If you are wondering what will be the cherry on top of your camping adventure, the answer is – the Slumberjack Country Squire sleeping bag. You might think that the high price is unreasonable, but you will rethink this statement once you hear the features this piece of gear possesses.

You have got synthetic insulation that will keep you warm even if the temperature outside reaches the alarming 20 degrees and a comfortable fold that acts as a blanket.

The buffalo plaid flannel liner adds to the softness of the sleeping bag, while the updated and improved foot box secures your feet in a safe spot. You can zip the bag up with a second bag and thus create a double bed, which is always better than one.

The Sierra Designs Frontcountry sleeping bag is the zipperless camping essential you wouldn’t be able to live without when you get a hold of one. Its synthetic fill is so soft it will remind you of your bed at home. The bag is oversized, which provides you with enough room to wiggle your feet and hands when stuck in it.

This is particularly handy for those of you who tend to be claustrophobic when placed in tight spaces. The insulated arm pockets aid in sealing out the cold air and welcoming the warm air that accumulates over time.

There is also a patented self-sealing foot venting system that enables your legs to feel fresh at all times. The sleeping pad located under the bag adds even more comfort and makes your hiking trip just that much better.
