Kelty Cosmic Down 5°F (-15°C) 550-Fill Sleeping Bag

Warm, comfortable and designed for colder adventures, the Kelty Cosmic Down combines lightweight down insulation with practical features for camping, backpacking and outdoor travel.

Its trapezoidal baffle construction helps retain warmth, while 550-fill down insulation provides a balance of warmth and packability. The semi-rectangular design and expanded natural-fit footbox provide additional room for a more comfortable night's sleep.

The shell and liner use fully recycled fabrics with a PFAS-free DWR treatment, while a full draft tube and collar help retain warmth in colder conditions. An internal zipped stash pocket keeps smaller essentials close at hand, and a stuff sack is included for easier packing and transport.
