Kelty Cosmic Sleeping Bag

The Cosmic 20 is rated for three-season use, meaning it is designed to keep you comfortable in temperatures down to roughly 20°F. It features an offset quilt construction to eliminate cold spots and an upper draft collar to help trap your body heat inside.

The CirroLoft ECO synthetic insulation is made from 100% recycled fibers and is designed to mimic the warmth and compressibility of down. While it is slightly heavier than down, it retains its insulating properties even if it gets damp, making it a reliable choice for humid or unpredictable climates.

The Long version is specifically sized for individuals taller than the standard model, typically accommodating users up to 6'6". It provides extra length to ensure you aren't compressing the insulation at your feet or head, which helps maintain the bag's thermal efficiency.

Kelty has included an anti-snag treatment on the zipper track to prevent the fabric from catching. Additionally, the dual locking sliders allow you to vent the bag from the bottom if you get too warm during the night.

Yes, the bag features an expanded, natural-fit footbox designed to give your feet more room to move. This shape is less restrictive than traditional mummy bags, allowing for a more natural sleeping position.
