The Feathered Friends Murre Light 0 is a women's-specific winter mummy bag rated to -17.7°C (0°F), with narrower shoulders than the men's cut and extra insulation concentrated in the footbox and torso, where cold tends to be felt most while sleeping. It uses 900 fill power goose down in a 7D Pertex Quantum Pro shell and weighs 1276 g total, lighter than the -10°F-rated Arctic Finch Light in the same women's line thanks to the less extreme temperature target.
A draft collar and draft tube limit heat loss at the neck and zipper, and the 3D anatomical hood is contoured rather than a simple drawcord closure. An internal pocket, stuff sack and storage sack are included, and the bag is made in the USA. Rated for 5-season use, it suits cold winter camping and high-altitude trips down to around -18°C rather than 3-season trekking, where it would be overbuilt.
