Our professional down sleeping bags are bluesign products with RDS-certified down and guarantee the best night's sleep after challenging trekking or mountain tours. The inner shell moulds itself perfectly to the contours of the sleeper, while the generous outer shell that allows it to stretch by up to 25 % width-wise ensures ample space. Thanks to the cut, the down loses none of its fluffiness or fill power. Elongated chambers prevent the down from bunching at the sides. The sensitive foot area is also provided with additional warmth, thanks to the three-dimensional foot-box with a particularly comfortable filling.
