Well protected even on cold nights. The Stoic Björkliden St. Hybrid -4°C sleeping bag features an insulating duck down filling with a loft of 700+ cuin. This makes the sleeping bag lightweight while still providing reliable insulation down to -4 degrees Celsius. Thanks to the thermal collar and the hood with drawstring, you are well wrapped up and heat loss is minimized. The two-way zipper allows for ventilation when needed. The cut is also suitable for side sleepers, and the pre-shaped foot box adds extra comfort. With this sleeping bag, bivouacking and camping are possible even on cold nights. Reliable moisture protection. The upper side and the entire foot area are protected by a particularly strong water-repellent outer fabric. This protects the down from moisture and prevents loss of insulation in wet weather conditions. The Björkliden St. Hybrid -4°C is compatible for pairing. Simply choose the left and right zipper models. On the go, the sleeping bag takes up little space in your luggage thanks to the compression sack. At home, the down filling can expand freely in the storage bag without losing any of its loft.
