The Womens Singi 3 Season Sleeping Bag from Fjallraven is a convenient down sleeping bag that offers a lot of warmth in relation to its weight. Takes up little space in the pack. Shorter in length & cut slightly wider around the hips, it is adapted to the body shape of a woman. Perfect for three-season use. Padded with high quality down that has been distributed for optimal insulation, with extra down on top & in the sections covering the body's core & feet. The head section is very warm & has a down-padded thermal collar with a drawcord adjustment that traps the heat inside the sleeping bag.
