Features :

• hermally-efficient patterning for an ultralight, ultra-packable bag : The custom mummy silhouette cuts excess material for ultimate weight savings and packability. Careful contouring, a shaped footbox, and tapered core give an ideal fit with no wasted space.
• Water-resistant down insulation ensures all-condition performance: The bag utilizes 800 fill power RDS-certified down with a PFAS-free hydrophobic treatment to provide an excellent warmth-to-weight ratio with weather-resistance to keep on insulating even when damp or wet. Products certified to the Responsible Down Standard (RDS) contain down or feathers from farms certified to animal welfare requirements.
• Innovative Thermo Gill vent provides built-in thermoregulation: A multi-stage zipper system on the front of the bag allows for micro adjustments in temperature range and fine-tuned heat regulation for changing conditions and differing sleep preferences.
• Designed to maintain comfort in variable conditions: In addition to the Thermo Gill vent on the body, the Headwall internal draft guard provides 360-degree protection. This plush, insulated collar wraps around the back of the neck and cozily overlaps itself in front to efficiently block cold air. For additional, instant ventilation, the footbox also features a zippered opening.
• Temperature range based on industry standard testing: A genderless bag, the Coda calls out both the Limit temperature rating and the Comfort temperature rating from ISO testing in its name. The Limit (lower) temperature is considered the benchmark for men, while the Comfort (higher) temperature is considered most applicable to women. Put another way...if you prefer to sleep with as few layers as possible, the Limit rating could be what you want to consider. A blanket hog who's always cold? The Comfort rating is probably the lowest temperature at which your bag is likely to provide a cozy night's sleep.
• NEMO takes full responsibility for all Endless Promise products: In addition to the recycled fabric of the shell and lining, NEMO's Endless Promise program aims to keep their products out of the landfill when they've reached the end of their useful life.
