1. Kelty Cosmic

Kelty Cosmic
Rated to: 20°F
Weight: 2 lbs. 10 oz.
Fill: 550-fill-power duck down
Best use: Camping

The Kelty Cosmic is a 3-season superstar, excelling when temperatures dip to subfreezing levels. Its trapezoidal baffle construction stands out as a key feature, effectively promoting heat retention and thermal efficiency. Filled with 550-fill-power down insulation, this sleeping bag ensures warmth while remaining quick-drying for added convenience. The 20-denier nylon taffeta outer shell strikes a balance between durability and a luxurious, buttery soft feel, complemented by a 50-denier polyester taffeta lining that is ultrasmooth on the skin. Equipped with thoughtful details, the Kelty Cosmic 20 enhances the camping experience.

The C0 and PFC-free durable water-repellent (DWR) coating effectively repels moisture, keeping you warm and dry inside. The internal zippered stash pocket is a convenient addition, providing a dedicated space for essentials like a headlamp, phone, or other camping necessities. The dual-sliding, locking anti-snag zipper ensures easy entry and exit, even during ventilation adjustments. With features like a draft collar and hood to keep hot air in and cold air out, as well as a spacious, natural-fit foot box for toe wiggle room, the Kelty Cosmic 20 sleeping bag delivers a comfortable and functional sleeping solution.

2. Sea to Summit Spark

Sea to Summit Spark
Rated to: 40°F
Weight: 12 oz.
Fill: 850-fill-power down
Best use: Ultralight backpacking

The Sea to Summit Spark Ultralight stands out as a remarkable choice for minimalist backpackers and warm summer adventures. It’s a fluffy sleeping bag designed for adults that weighs a mere 12 ounces and packs down to the size of a 1-liter Nalgene bottle. This bag embodies the essence of ultralight design. Its 7-denier and 10-denier fabrics contribute to its featherweight feel, while the 850+ fill-power Premium Goose UltraDry Down™ ensures optimal insulation. The bag is also certified to the Responsible Down Standard (RDS). The contoured mummy shape enhances comfort and efficient insulation, with vertical chest baffles preventing down migration.

However, the Spark’s minimalist design does come with some trade-offs. The 1/3-length zipper limits ventilation and provides less wiggle room. This makes it ideal for warm summer nights but less versatile for colder conditions. Additionally, the 10-denier shell demands careful handling, especially when exposed to rough ground. Despite these limitations, the Spark excels in disappearing into your pack or bike pannier. This makes it an excellent choice for mid-summer outings at low elevations where weight and packability are paramount. Its hydrophobic down also adds a layer of assurance in wet weather, setting it apart as a functional and ultralight sleeping bag for those who prioritize minimalist missions.

What I like: Crazy lightweight and wet-weather assurance of hydrophobic down.

What I don’t: The bag is warm enough to be used in summer only.

How to Choose the Right Sleeping Bag?

How to Choose the Right Sleeping Bag?

A good night’s sleep is crucial for an enjoyable and successful outdoor experience, choosing a sleeping bag is a decision not to be taken lightly. In this comprehensive guide, we will delve into the key factors to consider when choosing a sleeping bag to ensure it meets your specific needs and preferences.

Temperature Ratings

The first and foremost consideration when selecting a sleeping bag is its temperature rating. Different sleeping bags are designed to provide optimal comfort within specific temperature ranges. The industry standard uses three temperature ratings: comfort, transition, and extreme.

  • Comfort Rating: This is the lowest temperature at which an average person can sleep comfortably in the bag. If you’re expecting chilly nights, choose a bag with a comfort rating that matches or exceeds the expected low temperatures.
  • Transition Rating: Also known as the lower limit, this is the temperature at which the sleeping bag is suitable for a more experienced or warm-sleeping individual. It’s crucial to consider this rating for a more accurate assessment of the bag’s performance.
  • Extreme Rating: This is the survival temperature for the average adult woman. While it’s not recommended to rely on this rating for comfort, it can serve as an emergency guideline.

Understanding these ratings helps ensure that you select a sleeping bag appropriate for the climate and conditions you’ll be facing.

Insulation Type

Sleeping bags come with two primary insulation types: down and synthetic.

  1. Down Insulation: Known for its exceptional warmth-to-weight ratio, down insulation provides excellent thermal efficiency. However, it tends to lose its insulating properties when wet, making it less suitable for wet or humid conditions. Additionally, down sleeping bags are typically more expensive than their synthetic counterparts.
  2. Synthetic Insulation: Synthetic materials, such as polyester, are more water-resistant than down, retaining insulation even when wet. They are also generally more affordable and dry faster. However, synthetic bags are often heavier and bulkier compared to down bags with similar temperature ratings.

Consider the environmental conditions you’ll be facing and your budget when deciding between down and synthetic insulation.

Bag Shape and Size

Sleeping bags come in various shapes, each catering to different preferences and needs. The three primary shapes are mummy, rectangular, and semi-rectangular.

  1. Mummy: Tapered at the feet and hood, mummy-shaped bags are designed to minimize air circulation, providing optimal warmth. They are ideal for cold weather and backpacking due to their lightweight and compact design.
  2. Rectangular: Offering more room for movement, rectangular bags are suitable for those who prefer a less constrictive feel. They are great for car camping and warmer conditions but may not provide as much warmth as mummy-shaped bags.
  3. Semi-Rectangular: Combining features of both mummy and rectangular bags, semi-rectangular bags strike a balance between warmth and roominess. They are versatile and suitable for a variety of conditions.

Additionally, consider the size of the sleeping bag. It should provide enough room for you to move comfortably while minimizing unused space that can lead to heat loss. Many sleeping bags come in regular and long sizes, accommodating different body lengths.

Weight and Packability

For backpackers and outdoor enthusiasts on the move, the weight and packability of a sleeping bag are critical factors. Ultralight backpackers often prioritize lightweight gear to reduce the overall load. Down insulation bags are generally lighter and more compressible than synthetic ones, making them a preferred choice for those focused on minimizing pack weight.

Check the compressed size of the sleeping bag to ensure it fits well into your backpack, leaving room for other essential gear. Additionally, consider the compression method, whether it uses a stuff sack or a compression sack, as this can impact the ease of packing.

Sleeping Bag Features

Pay attention to additional features that can enhance your sleeping bag experience:

  • Hood: A hood helps trap heat around your head, providing extra warmth in colder conditions. Ensure that the hood is adjustable to customize ventilation.
  • Draft Collar: Placed around the neck, a draft collar prevents warm air from escaping and cold air from entering the sleeping bag.
  • Zippers: Look for quality zippers with reliable functionality. Some sleeping bags feature two-way zippers, allowing for ventilation at the foot or side.
  • Draft Tubes: These tubes run along the zipper to prevent cold air from seeping through, enhancing insulation.
  • Pockets: Internal or external pockets can be convenient for storing small items like a flashlight, phone, or eyeglasses.
  • Sleeping Pad Compatibility: Some sleeping bags are designed to integrate with sleeping pads, preventing you from rolling off during the night and enhancing insulation.


Choosing the right sleeping bag is a crucial step in ensuring a comfortable and enjoyable outdoor adventure. Consider your destination, expected weather conditions, personal preferences, and budget when making your decision. By paying attention to temperature ratings, insulation type, bag shape and size, weight and packability, and additional features, you can select a sleeping bag that meets your specific needs and contributes to a restful night’s sleep under the stars.
