Two laywers of insulation are laid on top of each other. The upper layer of insultion is sewn to the outer shell material and the lower layer of insultion to the inside lining.
Exosphere +2°, -4° & 8°
The layers of insultion are arranged with 3 times overlapping to increase the effective insulation thickness and avoid cold spots. This techniquie enhances sleeping bag performance.
Outer and inner shells are stitched direchtly to each other. These chambers contain the down.
Neosphere -4°, -10° & -15°
Opposing diagonal trapezoid pockets ensure the down is stabilised. Cold spots are thus avoided which is the best way to guarantee warmth insultion.
