Buyer's Guide

A Kelty 20 sleeping bag offers essential warmth and comfort for cooler weather camping and backpacking trips. Understanding its key features and requirements will help you choose the right bag for your outdoor adventures.

Temperature Rating and Warmth

The 20-degree Fahrenheit rating indicates the bag's effectiveness in cold weather. Fill power measures the insulation's quality, with higher values providing better warmth. Consider down or synthetic insulation based on your needs and environmental conditions.

Size and Fit

Measure your body dimensions to find a bag that fits well without excessive bulk. The bag should allow for proper sleeping positions while minimizing wasted space. Consider the length option (tall or regular) based on your height.

Weight and Packability

Backpacking requires a lightweight 20 sleeping bag to reduce overall gear weight. Look for bags that compress into small packages for easier transport and storage. The weight-to-warmth ratio affects your camping experience significantly.

Features and Durability

Choose bags with reinforced stitching at stress points and water-resistant exteriors for lasting performance. Consider additional features like zippers that unzip fully for easier access or ventilation options to adjust temperature during the night.

What temperature rating can I expect from a 20° bag?

A 20° rated sleeping bag, like the Kelty 20, is suitable for mild winter conditions and early spring/late fall use. You can expect it to keep you warm between 20° and maybe down to 10° Fahrenheit (-6° to -12°C).

The actual temperature you'll stay comfortable at can depend on factors including your body size, how much you move during sleep, and whether you can maintain a stable body position without adjusting the bag.

Is the Kelty 20 suitable for cold weather camping?

While the Kelty 20 sleeping bag is warm enough for most autumn and spring outdoor trips, it may not be ideal for harsh winter conditions or high-altitude skiing expeditions. Users should consider its 20° rating as an upper limit for comfortable outdoor use.

The bag's down fill and draft tube design make it suitable for cold weather camping when paired with appropriate base layers and a good sleeping pad.

What are the key features of the Kelty 20?

Key features include a two-way zipper, adjustable bungee cord hem, down fill, and rated to 20°F (-6°C). The bag offers good value with Kelty's 90-day satisfaction guarantee and comes with a stuff sack for storage.

How does the Kelty 20 compare to similar bags?

Compared to other bags in the same category, the Kelty 20 offers a similar warmth rating to many competitors. It holds its own against brands like Therm-a-Rest and NEMO in terms of insulation and design features.

Users often report it feels slightly heavier than some synthetic options at the same temperature rating, but many appreciate the warmth and down-feel of the filled bag.

Are there any downsides to the Kelty 20?

The main drawback is its weight, which can be an issue for ultralight backpackers. The down fill also makes it less compressible than synthetic options, which can be important when space is limited.

Additionally, users with broader torsos might find the standard fit too snug, though the adjustable hem helps some with this issue.
