Kelty Cosmic Sleeping Bag

The Cosmic 20 is rated for 20 degrees Fahrenheit, making it an ideal choice for shoulder-season camping. It provides reliable warmth from early spring through late autumn, though you may want a liner if you plan to sleep in temperatures consistently near its limit.

The bag uses 550-fill duck down, which is excellent for warmth and packability. While the shell features a water-resistant finish to repel light precipitation, down can lose its loft when wet, so it is best to keep the bag dry inside your pack or tent.

The mummy silhouette is designed to maximize thermal efficiency by keeping the insulation closer to your body. To ensure you don't feel restricted, this model includes a spacious foot box that allows for more natural movement while you sleep.

The bag is equipped with an anti-snag zipper draft tube. This feature is specifically designed to prevent the zipper from catching on the lining while simultaneously sealing in heat.

This specific model is designed for users up to 68 inches, or 5 feet 8 inches, in height. If you are taller than this, you may find the fit too restrictive.
