What You'll Learn
Cleaning and maintenance
To care for your Kelty Cosmic Down sleeping bag, it is important to follow some basic cleaning and maintenance routines. Here are some detailed instructions to help keep your sleeping bag in good condition:
Cleaning
- Spot clean: When you notice any stains or dirt on your sleeping bag, address them promptly. Use a mild detergent diluted in water and a soft cloth to gently dab and wipe the affected areas. Avoid rubbing or scrubbing, as this could damage the fabric.
- Hand washing: For a more thorough clean, hand washing is recommended. Fill a bathtub or large container with warm water and add a small amount of mild detergent. Fully submerge the sleeping bag and gently agitate the water with your hands to ensure the detergent is distributed. Let it soak for 10-15 minutes, then drain the water and gently squeeze or press the bag to remove excess water. Do not wring or twist the fabric.
- Machine washing: If your machine washer has a gentle or delicate cycle, you can consider machine washing your sleeping bag. Use a mild detergent and cold water to reduce the risk of damaging the fabric or insulation. Remove the sleeping bag from the washer as soon as the cycle ends and avoid using a dryer.
- Drying: After cleaning, thoroughly drying your sleeping bag is crucial. Lay the bag flat on a clean surface and allow it to air-dry completely. Avoid direct sunlight, as it could damage the fabric. You can also consider tumble drying on a no-heat or low-heat setting, removing the bag frequently to fluff and turn it for even drying.
Maintenance
- Storage: When not in use, properly store your sleeping bag to maintain its shape and insulation. Avoid compressing or squishing it; instead, hang it in a breathable storage sack in a cool, dry place. You can also keep it loosely stuffed in its storage bag.
- Regular inspection: Periodically inspect your sleeping bag for any signs of damage, such as rips, tears, or loose stitching. Address any issues promptly to prevent them from worsening.
- Ventilation: After each use, air out your sleeping bag to prevent the build-up of odours and moisture. Hang it in a well-ventilated area until it is completely dry before storing it away.
- Zipper care: Maintain the zipper by cleaning and lubricating it occasionally. Use a soft cloth to wipe down the zipper, removing any dirt or debris. Apply a small amount of zipper lubricant or candle wax to the zipper's teeth and pull tab to ensure smooth opening and closing.

Storage
To store your Kelty Cosmic Down sleeping bag correctly, follow these steps to ensure it stays in good condition and lasts a long time.
Firstly, always allow your sleeping bag to dry out completely before storing it. Moisture can lead to mould and damage the bag's insulation, so it's important to air-dry the bag fully after each use. Ensure it is thoroughly dry before moving on to the next step.
Next, loosely pack the bag into its storage sack. Avoid compressing it for long periods, as this can damage the insulation. Instead, store it in a larger sack or a bin/cotton bag, allowing the bag to loft and breathe. You can also hang the bag, but be sure to support the whole length, so it doesn't tear at the hanging points.
When storing, ensure the location is cool and dry. Avoid damp areas, such as basements, and keep it away from direct sunlight, which can degrade the materials over time. A temperature-controlled environment is ideal, helping to maintain the bag's condition.
Lastly, it is beneficial to keep the bag off the ground and out of reach of pests. Elevating the bag protects it from potential water damage and pests like moths, which could damage the bag.
By following these steps, your Kelty Cosmic Down sleeping bag will be correctly stored and maintained, ready for your next adventure.

Durability
The Kelty Cosmic Down sleeping bag is made with a burly 50-denier recycled polyester shell and a 20-denier recycled nylon liner, making it significantly tougher than other sleeping bags. The thicker shell fabric makes it one of the most durable backpacking sleeping bags on the market, capable of handling frequent use, rougher conditions, and general wear and tear. Its durability is further enhanced by its trapezoidal baffle construction, which helps the bag retain heat.
The bag's durability is also evident in its zippers, which glide smoothly without any noticeable snagging issues. The anti-snag zippers ensure that the bag doesn't get caught, while the full-length draft tube and insulated collar help to retain heat. The Kelty Cosmic Down sleeping bag is also available in a water-repellent version, which features a non-PFAS durable water repellent (DWR) finish to help shed moisture. However, it is important to note that the bag is not built for wet conditions, and keeping it dry with a waterproof stuff sack and proper tent protection is essential.
To ensure the long-term durability of the Kelty Cosmic Down sleeping bag, proper care and storage are crucial. Cleaning the sleeping bag is integral, especially when camping in areas with wild animals, as the smell of the bag can attract them. Additionally, regular stitching maintenance is necessary to prevent the feathers or fibres from migrating and creating cold spots. Adequate stitching will create cosy pockets where the insulation can fully loft for maximum insulation.
The Kelty Cosmic Down sleeping bag is a durable option for backpackers, offering a reasonable price point, a durable build, and practical features. Its rugged material and award-winning baffle design make it a reliable choice for those seeking a long-lasting sleeping bag that can withstand frequent use and varying conditions. Proper care and maintenance will further contribute to the bag's durability, ensuring a long life of comfortable camping adventures.

Temperature ratings
The Kelty Cosmic Down 20 Sleeping Bag is a budget-friendly option that offers good performance for shorter backpacking trips and car camping. Its temperature ratings are intended as a guideline for comparing products, rather than a guarantee of warmth, as several factors influence an individual's comfort during sleep. The bag has a comfort rating of 31°F and a lower limit rating of 21°F. The comfort rating is the temperature at which the bag will keep the average "cold sleeper" comfortable, while the lower limit rating is the lowest temperature at which the bag will provide warmth.
The bag's thermally efficient trapezoidal baffle construction and full-length draft tube help retain heat, making it suitable for three seasons. The trapezoidal shape is designed to optimise heat retention. Additionally, the bag features an insulated collar, further contributing to its thermal efficiency. However, the bag's 550-fill-power down impacts its warmth and packability, and it may run colder than its temperature rating.
The Kelty Cosmic Down 20 Sleeping Bag is best suited for summer camping and mild shoulder-season conditions. If you anticipate temperatures dropping below freezing, a warmer sleeping bag is recommended. The bag has been tested in environments with temperatures dipping into the 20s Fahrenheit, and individuals may struggle to stay warm even with additional layers. Therefore, it is essential to consider the expected temperatures when using the Kelty Cosmic Down 20 Sleeping Bag to ensure a comfortable and enjoyable outdoor experience.
