The Hannah LOFT 400 down sleeping bag, filled with quality European goose feathers, is ideal for use from spring to autumn. Goose feathers have a long service life with a ratio of low weight and packability and high warmth. Anatomical fit and sophisticated construction of the chamber filling will allow for a quality and comfortable sleep. The top ripstop nylon material has a DWR finish, which makes the fabric non-absorbent and water-repellent, so the filler stays dry. The L-shaped two-way zipper is covered with a reinforced anti-jamming joint and also an insulating pad that protects against cold leakage, in addition, the zipper can be unzipped and used as a sleeping bag or as a feather blanket. You'll appreciate the self-unzipping lock, if you fidget a lot while you sleep. It has a pillow pocket in the hood. The sleeping bag is great for alpine hiking, trekking and cycling.
