The Best Ultralight Budget Sleeping Bags for Backpacking, Cycle touring, and Bikepacking Compared
The lightweight sleeping bags listed here are certainly not the best in the market for backpacking, hiking, and bicycle touring, but do you really need the best?
The sleeping bag is probably the single most important piece of equipment when facing cold climates, but for most of us, who do not really travel in extreme environments, a budget lightweight sleeping bag would just to the job.
We selected 10 relatively cheap sleeping bags trying to feature different models for different travel conditions and traveler’s tastes.
Most of them will keep you warm down to 5°C, some even in lower temperatures, a few are instead designed to handle more tropical climates.

Understanding Sleeping Bags temperature rates
The EN 13537 Standard that is now used by many sleeping bag manufacturers, it is the official European criterion for the classification of sleeping bags.
The EN13537 applies to all sleeping bags with the exemption of sleeping bags for military use and sleeping bags for extreme temperatures (below -25°C).
To be labeled for the EN temperature rate, sleeping bags need to undergo a standardized lab procedure which determines 4 different factors, from Wikipedia:
Upper Limit — the temperature at which a standard male can sleep without excessive perspiration. It is established with the hood and zippers open and with the arms outside of the bag.
Comfort — the temperature at which a standard female can expect to sleep comfortably in a relaxed position.
Lower Limit — the temperature at which a standard male can sleep for eight hours in a curled position without waking.
These ratings are taken assuming that the subject is using a sleeping pad, tent and is wearing one base layer of thermal underwear. If you want to better understand this rating we recommend this article.
Unfortunately, brands are often not transparent about whether or not they refer to the EN standard, and which factor they consider when they state their sleeping bag’s temperature rating. Apparently, most refer to the lower limit, while others to the more relevant Comfort zone.
Moreover, it is important to be aware that standards like this cannot be taken as universal truths. Plenty of factors are involved in the temperature real feel, which varies widely from person to person. Hydration, nutrition, altitude, and quality of the other gear (sleeping pad, tent, clothes) are also very important factors.

Mummy VS Rectangular Sleeping Bags
The narrower the space inside your sleeping bag, the easier it will be for your body to warm up the air inside, thus giving you a feeling of warmth. That’s why real winter sleeping bags are always mummy shaped.
The movement though, inside a mummy sleeping bag is very constrained, forcing you to sleep in only a few positions, this can be hell for some (like me for example) and cause intense sweating when the temperatures get warmer.
There is nothing such a 4-season sleeping bag, 4-seasons means winter. If you’re going to hike, backpack, or bicycle tour across different climate zones there’s no way you’ll always be comfortable with the same sleeping bag.
Down VS Synthetic insulation
There are two types of materials used to fill a sleeping bag, bird downs (generally duck or goose) and synthetic materials. The cheapest sleeping bags are usually filled with synthetic materials, less efficient in retaining warmth compared to downs.
The lightweight sleeping bags listed here though, are not the cheapest on the market, but a decent compromise between price and quality. Indeed some of the best budget sleeping bags feature down insulation.
Other advantages of down are that they compress more (reducing the packed size), and are usually lighter.
Few more things to know about sleeping bags
Some sleeping bags feature waterproof coating, do not be fooled though, sleeping inside a wet bag will never be comfortable, so I won’t consider this as a decisive factor, although it will help a lot if condensation is an issue.
Another thing to consider is that not all down are the same: the filling power ratio is a value that measures the insulating power of the down filling.
A down filling power of 800 is considered high-quality, unfortunately, you’ll hardly find a budget sleeping bag with these characteristics.

Packed: 8 x 17 in
Naturehike is a recently established outdoor gear brand from China, which already received worldwide appreciation for its great quality/price ratio.
The Cicada’s wings 36°F is one of the lightest 36°F sleeping bags you can get your hands on. They have utilized twice as much insulation on the top of the bag as the bottom to maximize warmth to weight ratios. Not only this but the top of the bag utilizes 800 fill power down insulation while the bottom of the sleeping bag utilizes synthetic insulation.
Weighing only 1.25lb it packs extremely small with the included 4-point compression sack, down to just 10 x 5 inches.
The Cicada’s wings 36℉ ultralight sleeping bag uses light and tough materials. The 15D ripstop fabric allows you to shave weight off of the sleeping bag, making this budget sleeping bag one of the best available if you’re looking for the comfort given by the rectangular shape. The downside is that it doesn’t have a hood.

Aegismax 15 Degree Down Sleeping Bag
This 15 Degree Down Sleeping Bag by Aegismax has more room in the shoulders and hips than traditional mummy bags, so you can move around while you sleep. Ideal for spring, summer, fall, and even warmer winters.
The 90/10 down insulation has a good warmth to weight ratio for the price. The bag is rated 15°F but I won’t risk it honestly, although it seems a good budget sleeping bag for relatively cold climates, should be warm enough at 32°F or even below.
Downsides are the lack of a draw-string around the neck, the lack of a hood, and the name of the brand, which really is unknown to the world.
Strong points are its lightweight, very small packed dimension, and the cheap price. An interesting product I would like to test.
