Scoring 5 out of 5, The Western Mountaineering MegaLite sleeping bag takes the cake for best overall sleeping bag due to its high-quality materials, spaciousness/comfort, and versatility.
This made in the USA bag contains a lightweight shell fabric called “extremelight”. It is lightweight yet remains strong and durable. Not only is the fabric strong, it will compact to a very small size. The MegaLite also has buttery smooth internal fabric in addition to the fluffy goose down. There is stiff fabric along the zipper for reinforcement to prevent catching and tearing.
With dimensions of 64” for shoulders, 56” for waist, and 39” for feet, you will be able to sleep in any position desired. Those who toss and turn while sleeping, this is the bag for you. If you aren’t a mummy bag person, you will most likely enjoy the MegaLite for its generous dimensions. High-quality nylon fabric and 13 ounces of European goose down will make you feel as cozy as you would be in your own bed at home.
Although this bag comes with a hefty price tag, the MegaLite performs the best in most climates and has an exceptional balance of weight and internal dimensions. At 1.5lbs, this sleeping bag will fit perfectly into your sleeping system. The MegaLite is roomy enough for camping but also compressible for long backpacking and mountaineering trips. With a temperature rating of 30°F, you will sleep comfortably in most cold conditions.
If you could buy one bag, the MegaLite does it all. The quality is superb and it is light, packable, spacious, and warm.
The North Face Cat’s Meow is another budget bag in addition to the Kelty Tuck 20 (see below). The Cats Meow at $169, is also synthetic but lighter than the Kelty Tuck.
This is a staple North Face bag that has been around since in the 1970’s. Needless to say, North Face has had plenty of time to perfect the Cats Meow. It is lighter than most synthetic bags, outstandingly versatile, and durable against wet weather.
As a 20°F bag, tests have shown that it is warmer than the Kelty Tuck due to North Face’s Heatseeker Pro synthetic insulation. This insulation is quicker at drying than some water resistant down materials. At 2.69lbs, it is heavier but not as heavy as some other synthetic bags.
The bag has features like a full-length glow in the dark zipper, hood, internal pocket, and compression sack. The Cat’s Meow is a top contender for a budget and general-purpose sleeping bag.
Due to its weight, this bag is not recommended for extended trips but best for short-term adventures like camping or kayaking.
A fantastic price-conscious sleeping bag that you could take on almost any adventure. The Cat’s Meow will you keep you warm and dry, and you’ll never be stuck looking for the zipper at night.
The Kelty Tuck 20 is a wonderful sleeping bag for its value, design, and price. At $89, you will experience some exceptional features. This bag turns into a wearable cocoon with the opening of the foot box. You are also able to fully unzip the bag to lay flat as a blanket.
This bag has fantastic ventilation and temperature regulation. When too hot, you are able to unzip the foot box completely to allow your feet to ventilate, while your body remains covered.
The temperature rating is at a consistent 20°F as it is insulated with Thermapro Synthetic, designed to retain heat and compress. The Tuck includes many other features like a hood, internal pocket, and anti-snag zippers.
The Tuck is fairly roomy, yet there are no cold spots due to the effective quilt construction. At 3 lbs, the bag is on the heavier side, but not unmanageable.
Synthetic bags generally weight more than down. The Tuck can be compressed but still remains quite bulky. If you are looking for a basic sleeping bag that is inexpensive and will handle warm climates and mild winter conditions, the Tuck is for you.
This is a great bag at a great price point. Ideal for beginners in camping/hiking or those who need a simple bag and don’t mind the weight and bulk.
The Seattle based Feathered Friends Company specializes in custom high-quality down products at a competitive price.
The Editors Choice comes in at a close second to the MegaLite but at a better price. The Feathered Friends Swallow Nano 20 will be in the $429-$450 range as opposed to the $470 for the MegaLite.
Not a huge difference, but every dollar counts.
The Swallow Nano 20 withstands a temperature of 20°F, has 16.8 ounces of 900-fill goose down, and a water-resistant shell. You can’t go wrong with a lightweight bag made of high-quality materials.
However, Nano doesn’t compete with MegaLite’s spacious internal dimensions. Nano has dimensions of 60” at the shoulders, 56” at the hips, and 38” at the feet.
You will feel more constricted in this bag compared to the MegaLite even though they are both mummy style.
This USA made bag is a strong competitor to the MegaLite. It outperforms in temperature rating, weight, and cost.
The Marmot Phase 20 is comparable to the MegaLite and Swallow Nano 20. It earns gold stars for its weight, packability, and warmth. At 1.44lbs, with a temperature rating of 20°F, and 850+ fill power goose down, you will not be disappointed with the Phase 20. It contains all the inner makings of a fantastic sleeping bag.
The Phase 20 has an excellent balance between weight and warmth. It is filled with 14.1 ounces of down to keep you warm and the down is treated with DWR to be weather resistant. The hood is exceptionally cozy and contains heat. The internal fabric is soft and silky and includes a pocket for your belongings. The full-length zipper allows you to open the bag for ventilation when hot.
The Phase 20 is one of the most lightweight 20°F bags on the market. This is because of its ultralight shell fabric, high quality fill, and low-gauge zipper. It is by no means a “wide” bag but does have adequate room in the shoulders and hip. All of this and it still compacts like a dream. It is lightweight enough to take on extended trips but also insulated to stay at its temperature rating.
The Marmot phase is designed for three season use. It is just as pricey as the MegaLite or Swallow Nano 20 but it is lighter in weight.
A great value for money 20°F bag, it is superb for its lightweight and compression.

The drift’s interior is spacious and the bag also has a cozy hood and draft collar. There is an internal pocket to hold your belongings.
The Drift is one to beat for weather resistance. The outer shell is treated with DWR (durable water repellent), Downtek (treatment to speed up drying time), and a durable draft tube to prevent any moisture from entering through the zipper.
These 3 levels of defence make this bag perfect for winter camping, ski touring, and mountain climbing. The drift utilizes the highest quality materials and remains reasonably light in weight. The price certainly reflects this.
The drift is amazing at keeping you warm and comfortable in the coldest and wet of conditions. With its warmth-to-weight ratio, it is difficult to beat and the price is up there to show for it.

With this bag being so lightweight, it packs down to a size where you might even forget you are carrying it. The shell fabric is also naturally water resistant which will never wear off.
There is great attention to detail in this bag. Especially in the durable full-length zipper, neck collar, and drawcords at the foot box and neck collar.

A sleeping bag is one the most expensive things in your pack. A bag should be warm, lightweight, comfortable, versatile, and have helpful features. Read this guide and you will make the right decision.
Today’s market offers some of the best technology to date: the warmest of sleeping bags at the lightest of weight. Sleeping bags range drastically in price, quality, and versatility. It is difficult to know where to start and how to choose the perfect one.
Once upon a time, most hikers would hit the road with a 1-2 season sleeping bag and hope for the best. Now, sleeping bags are designed for 3-4 seasons. This way we can predict exactly which sleeping bag we will need depending on which temperatures we face.
Sleeping bags come in several shapes and sizes. For example, the shapes of bags include mummy, rectangular, semi-rectangular, and age/gender specific. The mummy shape is ideal for maximizing warmth while remaining lightweight. The rectangular shape is most “bed like” and offers roominess and comfort. Semirectangular is the in-between of mummy and rectangular. Age and gender are specifically designed to fit children, men, or women.
There are several ways brands categorize temperature ratings in sleeping bags. They are labeled with comfort, limit, and extreme (average comfortable sleeping temperatures) or seasonal ratings. The seasonal ratings are: one season: 40°F, two seasons: 32° to 40°F, three seasons: 23° to 32°F, and three+ seasons: 14° to 23°F.
There are two types of sleeping bag insulation: down or synthetic. Down compacts effectively and is pricier, while synthetic is bulkier and cheaper.
Here are the key features you should look at when buying a sleeping bag.
Your body heat is what keeps you warm in a sleeping bag. Choosing a bag with high-quality insulation will retain that heat and give you a good nights rest.
Sleeping bags insulated with down are the most popular as they are lighter and compact easier. Down bags are fluffier and retain heat, but will absorb moisture in a wet climate. Purchasing a bag with water-resistant down insulation can prevent this issue. Fill power is also something to look for when purchasing a down bag. Anything over 800 fill power is considered high quality down and this is where down sleeping bags become pricey.
Synthetic, a popular campers choice, is a less expensive and more ethical option, as it uses no animal products. Synthetic does not compact well and will be bulky in your pack. Although, it does a better job when it comes to retaining heat when wet.
Choose a sleeping bag that will withstand lower temperatures than what you predict. When expecting near-freezing temperatures, purchase a 20°F bag, not the 35°F. If it becomes too hot, you will always be able to open the bag for circulation.
Your sleeping bag will be one of the heaviest items you will carry. It’s important you find a bag that gives you the perfect balance of warmth, comfort, and weight. It is recommended that you use a sleeping pad in conjunction with your bag for ultimate comfort. It is important that you are aware of the weight of your pack so you will be able to carry it comfortably. A rule of thumb is to keep your “sleep system” (sleeping bag and pad) under three pounds. You can achieve this with a sleeping bag under two pounds and pad under one pound.
The packed size is how compressed you sleeping bag can be. This depends on the down fill power or synthetic insulation, inner/outer fabric, and other features (zippers, velcro, etc.). When the fabrics are lighter and the insulation is higher quality you will have an outstanding compressible bag.
If you are going to spend more time carrying the bag rather than sleeping inside of it, place higher importance on the weight/bulk of the bag.
The comfort of a sleeping bag relies heavily on your personal sleeping style. If you are a warm/cold sleeper, side, tummy, or fetal position sleeper, you will want extra space to move around or a warmer bag. However, remember you don’t want too much space as this creates cold spots. Down insulation tends to provide more cushion and comfort then synthetic. Add a sleeping pad to make your sleep even more comfortable.
It is a best to physically try out sleeping bags before purchasing to make sure it is the shape and size that you want.
When purchasing a sleeping bag, especially an expensive one, you want to make sure you are getting the value you paid for. The bag needs to be versatile in that it can handle various conditions, environments, temperatures, and elevations.
For example, a sleeping bag which has horizontal baffles (the seams running across the bag, keeping the insulations in-tact on the inside), allows one to move upwards if it is too warm, and downwards if too cold. A longer zipper prevents you from feeling constricted and allows your body to vent in warmer months.
A sleeping bag can have many features of design, including shell fabric, draft tubes, zippers, neck baffles, and stash pockets. A simple design element, such as the zipper can really make or break a sleeping bag. If the zipper is poor quality, it can get caught or break, making your sleep uncomfortable and cold. The Marmot Phase 20 and Western Mountaineering Ultralite have excellent quality zippers.
Other features include a hood, pillow pocket, and an internal pocket for your belongings. A hood is crucial in the colder months for warmth and coziness. A pillow pocket is a great addition where you can put clothing for a makeshift pillow. An interior pocket is helpful to keep your phone and other belongings safe. These are all the features that a sleeping bag should have. The more design elements, the heavier the bag.
Stuff sacks come with most bags but they usually aren’t effective. It’s best to purchase one separately so your bag can actually be compressed to the fullest capacity. A sleeping bag liner is also a smart measure to keeping your bag new and clean, it will also add warmth.
