Deuter Neosphere -4° Regular

Deuter Neosphere – the new down sleeping bags with maximum insulating qualities! We use our Thermo Stretch Comfort System on the inside: the lining is constructed with elastic seams allowing the bag to expand up to 25% in width. However, the shell has a roomy cut and thus not only keeps the loft of the down, but enhances the insulation by providing even more space for the down to expand. Compared to other down sleeping bags without Thermo Stretch Comfort, the insulation properties improve at an average of 2°C. The head and foot section are ergonomically cut. The 3D hood protects the sleeper’s head, while the Ergo Foot cut with its extra thick fill in three chambers guarantees warm feet. Trapezoid chambers keep the down evenly distributed and prevent cold spots. The new bags thus present a fantastic warmth-to-weight ratio.
