Haglöfs is a veteran manufacturer when it comes to making sleeping bags and it shows: the quality is great, and so is sleeping comfort. This model is suitable for 2 - 3 season use. - Narrower at the shoulders compared to most bags: a good choice for women and other people with narrow shoulders - Extra insulation at the foot box and chest - A well-fitting hood - Tri-Fusion synthetic insulation - Surface fabric: 50 denier ripstop polyester - Liner fabric: 75 denier polyester - ¾ length two-way zipper on the left side - A nifty pillow pocket on the inside - Hanging loops for airing It's wise to store the bag outside of its compression bag at home, as storing in it will cause the bag to lose some of its insulation over time.
