• In each chamber, the amount of feathers is precisely calculated per gram for minimum weight and maximum warmth. This innovative "Chamber by Chamber" approach was developed by Matt Fuller, who is the only outdoorsman with a PhD in feather research.
• Structurally exceptional insulation - the so-called Body-mapping takes into account the needs of each part of the body separately. That's why Matt Fuller calculated the exact feather density in each chamber separately.
• Anatomically shaped hood - The hood is designed to perfectly protect your head from heat loss and thus ensure a comfortable sleep.
• Ergonomic shape for the feet - the feet need to be insulated as best as possible, because they get little blood flow. The bottom of the sleeping bag is tapered in the shape of a trapezoid and the tip area is raised like a shark's fin. Thanks to this ergonomic shape, you will not press the chamber in the leg area with your feet and the insulating properties that keep your feet warm will not be lost. The bottom of the sleeping bag is made separately and then sewn to the sleeping bag.
