Reviews - The Best Budget Sleeping Bags for Backpacking

Sea to Summit Trailhead ThII 30

  • Insulation: Synthetic
  • Weight: 2 lbs 5 oz
  • Shape: Semi-rectangular
  • Temperature Rating: 30 (F)
  • Extra Spacious
  • Second Zipper In Footbox
  • Full Length Zipper To Convert Sleeping Bag Into A Quilt


The Trailhead ThII 30 is another synthetic sleeping bag that retains its insulation abilities even when wet. It uses a unique WaveLoft technique that tangles filling fibers for maximum heat retention up to 30°F. This bag has a tapered rectangular shape, providing you with comfort and room to move. An oversized anti-snag zipper draft tube will guard your whole body against cold chills when you snuggle down in this bag. 

An important characteristic of the THII 30 is its versatility. Its full-length zipper lets you turn this sleeping bag into a quilt. Furthermore, there is a second zipper in the foot box, allowing ventilation for your feet and broad temperature adjustability. Plus, to prevent your frustration, the bag’s lining fabric is directly attached to the shell fabric, which prevents zipper tangles.  This sleeping bag is excellent for backpacking since it weighs about 2.5 lbs – not much more than most ultralight sleeping bags!

Sea to Summit Traverse TvII 25

  • Insulation: Synthetic
  • Weight: 2 lbs 7 oz
  • Shape: Semi-rectangular
  • Temperature Rating: 25 (F)
  • Very Comfortable And Spacious
  • Lightweight Compression Bag
  • Can Be Used As A Comforter


Just like the Sea to Summit Trailhead THII 30, this sleeping bag has a tapered rectangular shape and uses the WaveLoft construction for increased comfort. However, the Traverse TVII 25 has a more expanded range of features. It can withstand temperatures as low as 25°F, allowing you to explore slightly colder environments. And an oversized, anti-snag zipper and a neck draft tube provide exceptional resistance to chilly mountain breezes. 

A Free Flow zipper system in this bag comes with three features that let you customize your temperature. A full-length main side zipper, a half-length opposite side zipper, and a foot zipper all provide you with unrestricted movement and ventilation. As a bonus, the TVII 25 can be zipped up with another bag. This versatility makes up for its higher price, delivering you your money’s worth.

  • Two Way Zipper
  • Can Be Attached To Another Right-Zip Sleeping Bag


The Lost Dog is a cold-oriented sleeping bag that withstands temperatures up to 15°F. It uses FireLine ECO synthetic insulation made from recycled polyester, and the innovative design includes several features for comfort. It has a Free Range hood that allows you to lift your head while keeping a snug fit around your face. The Free Range foot box is similar, giving you some wiggle room. An additional no-draft collar will keep the cold wind out. 

For convenience, a Flex Pad Sleeve can stretch over an insulated sleeping pad for extra warmth. The bag also has a 2-way anti-snag zipper and can be joined with another right-zip sleeping bag. If that doesn’t sound comfy enough, the Lost Dog offers a Pillow Barn feature that makes sure your pillow stays put all night. Although it is on the pricier end of affordable, the extra features make it worth it.

  • Insulation: Down
  • Weight: 3 lbs 14 oz
  • Shape: Mummy
  • Temperature Rating: 0 (F)
  • Water And Moisture Repellent
  • Great Loft And Warmth
  • Thermally Efficient And Roomy (to keep you warm and comfy all night long)


Being the most expensive bag on this list, REI Co-op Downtime is also the warmest. It will safeguard you against frigid temperatures as low as 0°F. A durable water-repellent (DWR) shell keeps the down in this bag dry and lofty even in damp conditions. The REI Co-op Downtime 0 has a contoured hood, an oversized face muffler, and full-length draft tubes that all work to trap warm air while fighting off the cold. 

Despite being a traditional mummy shape, this bag provides a relaxed fit around the shoulders and hips, so you don’t feel restricted while sleeping. Another handy feature is the presence of different drawcords that let you adjust the hood or the neck yoke in the dark. Finally, the pad loops provide secure points of connection to your sleeping pad.

The North Face Furnace 20

  • Insulation: Down
  • Weight: 2 lbs 10 oz
  • Shape: Mummy
  • Temperature Rating: 20 (F)
  • Great Humidity And Moisture Control
  • Fitted Hood For Extra Comfort
  • Fast-Drying


The North Face Furnace 20 is a great and affordable option if you are looking for a warm sleeping bag to use in unstable weather. Although it’s filled with fast-drying down, it also uses anti-compression synthetic insulation on the bottom for added warmth. This 3-season sleeping bag provides a draft collar and a fitted hood to trap warm air. Additionally, the vaulted foot box also allows for unrestricted movement. 

The bag’s shape is mummy, but less tapered than usual, resulting in extra roominess. Overall, the Furnace 20 is suitable for backpacking in wet and chilly environments. It has a durable water-repellent shell coating and an average weight of around 3 lbs.

Big Agnes Camp Robber

  • Insulation: Down
  • Weight: 2 lbs 1 oz
  • Shape: Rectangular
  • Temperature Rating: 45 (F)
  • Water Repellent Finish (to keep your bag from getting wet)
  • Comfortable Pillow Barn (to keep your pillow in place throughout the night)
  • Includes A Mesh Storage Bag


The Big Agnes Camp Robber Single Bedroll Blanket is as versatile and functional as you can imagine. Thanks to its quilted construction, you can connect it to a sleeping pad to make a comfortable sleeping bag. Alternatively, you can use it as a blanket or as a plush down throw. There is also a sleeping pad cover with a comforter that you can detach to transform the Camp Robber into a summer sleeping bag. Easy valve access lets you adjust and customize pad inflation even while you’re laying on it. 

The Camp Robber has adjustable compression straps, allowing for seamless packing and a tight roll. Along with the light weight of only two lbs., this makes it perfect for on-the-go camping. For added comfort, it features a Pillow Barn that will keep your pillow in place the entire night.

Therm-a-Rest Space Cowboy 45

  • Insulation: Synthetic
  • Weight: 1 lbs 4 oz
  • Shape: Mummy
  • Temperature Rating: 45 (F)
  • Water Resistant
  • Highly Compressible
  • Cinchable Hood And Snag Free Zipper


The Therm-A-Rest Space Cowboy 45 is an awesome ultralight mummy-shaped sleeping bag. Its compressed volume of 2 liters makes it highly packable and lightweight. Because this sleeping bag only withstands 45°F, it is better suited for warmer weather and summer camping. However, you can layer it with other quilts using blanket loops on the bag, expanding its versatility. Additional removable connectors even let you fasten a sleeping pad to the bag. 

The Cowboy 45 uses water-resistant synthetic fill that retains its insulation abilities even when damp. It is strategically placed in certain areas to optimize warmth and weight. The ThermaCapture lining efficiently traps body heat. Additionally, a cinchable hood also guards against unwanted drafts. All these features make the Space Cowboy 45 a great companion for backcountry travels.

This affordable sleeping bag is a real find for travelers wishing to explore cold environments. With a durable SpiraFil synthetic insulation, the sleeping bag will keep you warm at temperatures as low as 1.9°F. A 3D hood will provide warmth and comfort for your head; you can also cinch it tightly around your face during freezing nights. Another great feature of the Marmot Trestles is the foot box, which ensures extra comfort and warmth where it’s most needed. 

The Trestles 0 has a full-length, two-way zipper built to prevent snagging. There is also a fold-down second zipper that provides fresh ventilation. In case you need anything during the night, there is an external stash pocket for your essentials. Additionally, the bag has two hang loops for storing or drying out the bag.

It uses synthetic PrimaLoft Synergy insulation to keep you warm and snuggly in your hammock. A convertible footbox lets you either tuck your feet in or stick them out to keep them cool. An additional insulated draft collar will shield your head and neck against unwanted chills. 

Furthermore, the Vesta’s shape allows for both a comfortable fit and easy access. The set-up was designed to be simple, quick, and convenient. Plus, you can layer this bag with any other quilts or blankets you have to stay warm in colder conditions.

  • Temperature Rating: 20 (F)
  • Water Repellent To Avoid Moisture And Stains
  • Extra Spacious For Increased Comfort
  • Three Two-way Zippers
Sea to Summit BaseCamp BcII 20


While the BaseCamp BCII 20 doesn’t have any outstanding features, it is a great all-around sleeping bag. It comes with synthetic WaveLoft insulation, reducing heat loss without being stuffy. It will keep you snug even at 20°F, making it a perfect 3-season sleeping bag. The bag has a spacious design, and the lining fabric is attached to the shell fabric. Thus, you will have unrestricted sleep while not worrying about fabric tangles.

The BCII has a sophisticated system of zippers that increase adjustability and convenience. Three two-way zippers aid in ventilation if you are feeling too hot during the night. Additional zippers give you the option of joining your bag with another. As a bonus, you can unzip the top of the bag to turn it into a summer quilt.





Since you’ll likely be carrying the sleeping bag on your shoulders for hours on end, the first thing to check before buying is the weight. Long-distance hikers tend to prefer ultralight sleeping bags as they can weigh as little as 1 pound. However, ultralight bags tend to be far more expensive than standard sleeping bags.

Budget-conscious backpackers camping in warmer seasons can opt for a standard sleeping bag weighing around 2 lbs. If you’re an explorer planning to camp in freezing temperatures, you’ll probably have to carry at least a 3 lb sleeping bag on your shoulders to maximize warmth. To minimize weight while alpine camping, you’ll need to invest in a more expensive ultralight bag.



Sleeping bags can come in a rectangular, semi-rectangular, or mummy shape. The ideal choice for backpackers looking for minimal packing size and maximum warmth is a mummy-shaped sleeping bag. This bag shape tends to be on the lighter side because it’s constructed with less material.

Mummy-shaped sleeping bags fit tightly around the body, allowing for little or no movement during sleep, but superior warmth. Rectangular and semi-rectangular sleeping bags are looser around the lower body, so they are more suitable for those who tend to change position while sleeping.

Because of their shape, rectangular sleeping bags are the bulkiest of the three types, while semi-rectangular bags offer the best compromise between roominess and packability.



Most sleeping bags follow a standardized temperature rating system, which indicates the lowest temperature at which the sleeping bag ceases to serve as adequate protection against the cold. Sleeping bags are tested by independent organizations that establish how cold it has to be for an “average sleeper” to feel uncomfortable.

The number found after the sleeping bag name is the temperature rating. If low weight is a priority, summer sleeping bags with a temperature rating of 32°F or more are lighter in weight than 3-season or winter sleeping bags, as they contain less insulating materials.



Two types of insulating material are used in sleeping bags, synthetic fiber, and goose or duck down. Sleeping bags filled with synthetic fibers have the advantage of being fast-drying, cheaper, and non-allergenic. However, they offer less insulation than down sleeping bags. Down sleeping bags provide maximum protection against the cold and are usually lighter in weight than synthetic sleeping bags, but they tend to be more expensive.



Especially on multi-day adventures, you don’t want to waste any space in your fully loaded backpack. When selecting a budget backpacking sleeping bag, you’ll want to check its packed volume to make sure it won’t occupy too much precious space in your luggage. The volume of a sleeping bag is measured in liters, and a highly compressible bag shouldn’t take up more than three liters of space.





The insulating material found inside the sleeping bag.


The insulating material made out of the smaller plumage found under the feathers of ducks and geese.


The polyester fibers that can replace down in summer and 3-season sleeping bags. Synthetic-fill is cheaper and dries faster than goose or duck down, but it is also less insulating.


The outer material of the sleeping bag, normally made out of a nylon or synthetic material and a layer of water-repellent coating.


Zippers designed so that they don’t get caught in the fabric of the sleeping bag when in use.
