Kelty Cosmic Sleeping Bag

With a temperature rating of 20°F, this bag is designed for three-season use. It will keep you comfortable during chilly spring and autumn nights, but it is not intended for sub-zero winter expeditions.

The bag weighs 3.94 lbs. While it is not the lightest ultralight option on the market, it compresses well for its class and includes a stuff sack, making it a reliable choice for standard backpacking trips.

Mummy bags are designed to be snug to maximize heat retention, but this model features an expanded footbox. This design provides extra room for your feet to sit naturally, which helps reduce that confined feeling.

No, the PFC-free DWR finish is water-resistant, not waterproof. It will protect the down insulation from light moisture and condensation, but you should still use a waterproof stuff sack or pack liner to keep it dry during heavy rain.

This specific model is designed for users up to 68 inches (5'8") tall. If you are taller than this, you may find the bag too short to fully enclose your head comfortably.

The bag features dual-slider zippers, allowing you to unzip the bottom or side independently. This lets you vent heat from your feet or torso without having to open the entire bag.
