The Feathered Friends Arctic Finch Light -10 is a women's-specific winter mummy bag rated to -23.3°C (-10°F), cut with narrower shoulders than the men's equivalents but roomier through the chest and elbows, following the shape most women's-specific bags use to reduce dead air space without restricting arm movement. It uses 900 fill power goose down in a 7D Pertex Quantum Pro shell, at a total weight of 1344 g.
A draft collar and draft tube limit heat loss at the neck and zipper, and the 3D anatomical hood is contoured to the head rather than relying on a drawcord alone — both matter at temperatures this low. An internal pocket, stuff sack and storage sack come included, and the bag is made in the USA. As a 5-season expedition-rated bag, it's built for genuine winter and high-altitude conditions rather than shoulder-season use, where its weight and warmth would be more than necessary.
