Temperature ratings in Celsius
- ISO comfort: −3°C
- ISO lower limit: −9°C
The −9°C model name refers to the lower-limit rating. Comfort is the more useful starting point if you sleep cold. Lower limit describes a warmer sleeper curled up to retain heat; it is not a comfort guarantee. Allow a margin for your conditions and use an insulated sleeping mat.
Zip and construction
- RDS-certified 900+ fill power goose down with water-resistant Ultra-Dry Down treatment.
- Breathable 10D nylon shell and liner, with extra water resistance at the hood and footbox.
- Box-wall baffles help maintain an even spread of down.
- Full-length side zip, separate footbox zip and opposite shoulder zip. The Free-Flow system lets you vent your feet or open the bag flat as a quilt.
