The NEMO Coda 25/35 Endless Promise Sleeping Bag packs down to a small, light package to take weight off our shoulders during grueling miles on the trail. The hydrophobic 800-fill down provides consistent, reliable warmth, even in damp conditions, and the DWR treatment on the outer fabric repels condensation in our tent to keep the down light and fluffy. The single Thermo Gill vent can be easily opened and closed, allowing us to sleep at the perfect temperature all through the night. The bag is sustainably made using recycled materials, and at the end of its functional days, the entire bag can be recycled.
