Kelty Cosmic Sleeping Bag

The 20°F rating is a standard comfort limit for most users, making this bag ideal for three-season camping. If you are a cold sleeper, you may want to pair it with a high-R-value sleeping pad to ensure you stay warm when temperatures dip near that lower limit.

Traditional mummy bags often taper tightly at the feet, which can feel restrictive. The Cosmic features an expanded, trapezoidal footbox that allows your feet to rest in a more natural position, giving you extra room to move without sacrificing heat retention.

Yes, down insulation performs best when kept dry and lofted. While the bag features a PFC-free water-repellent finish, you should store it uncompressed in a large mesh bag or hanging up to maintain the loft of the 550-fill duck down over time.

Absolutely. The bag is equipped with dual-slider locking zippers, which allow you to unzip the bottom or side to create airflow while keeping your upper body covered. This makes it much easier to regulate your temperature as the night progresses.

This specific model is designed for users up to 68 inches (5'8") tall. If you are taller than this, you will likely find the bag too short to fully seal the draft collar around your shoulders.

At 3.94 lbs, this bag is a solid choice for car camping or shorter backpacking trips where weight is a consideration but not the primary focus. It balances durability and warmth, though ultralight enthusiasts might find it slightly heavier than specialized, high-denier technical bags.
