Fabric Options
Technical: With a Cire exterior and interior, this is the lightest option. Cire, a nylon taffeta, is tightly woven and treated for down-proof performance and reduced weight, with a luxurious cotton-like feel.
Comfort: For those who prefer cotton, this option has a Cire shell with a cotton lining.
Hood
The Cecilia series is designed for ultralight hiking and warmer climates, so the wide mummy is hoodless in this series.
