The Zenith 0 is a lightweight, cold-weather down bag built for campers demanding maximum thermal efficiency and minimal pack size. Designed to handle frigid backcountry nights, this bag delivers dependable warmth when temps drop below freezing while keeping your luggage load light and compact. To be honest, this might be overkill for most motocampers, but a good option if you plan on car-camping in Utah during the off-season.
The bag features a lightweight 20D polyester ripstop shell that resists abrasion while keeping overall weight to just 3 lbs 5 oz. Its contoured mummy design, insulated chest baffle, and adjustable hood work together to seal out freezing drafts. The water-resistant down treatment safeguards the fill against internal condensation and ambient moisture, ensuring maximum heat retention even on damp overnight stops. Packed into its included compression sack, the Zenith 0 squeezes down into a remarkably manageable footprint for a true zero-degree bag.
Why We Like It
When riding during Utah's shoulder seasons, overnight temperatures at high elevation campgrounds can drop below freezing as soon as the sun goes down. Packing enough insulation on a bike usually means sacrificing massive amounts of pannier space. The Zenith 0 solves this using 600-fill-power, RDS-certified hydrophobic down, giving you exceptional loft and packability without the penalty of heavy bulk.
Note:
To preserve the loft and performance of your down insulation, avoid keeping the Zenith 0 compressed long-term. Upon returning from a trip, remove the bag from its compression sack and store it uncompressed, either hanging in a dry space or inside a large mesh storage bag.
