The sleeping bag is sewn from Steel-Grey. The zipper is collateral fitted at mid length and is silvered to provide an integrated shielding. The inner cover, made of cotton fabric, is removable and fixed with a hook and loop fastener. The inner cover will ensure your scratch free sleep, even without pyjamas. If required the head area can be tightened with an elastic cord, so that only the face is uncovered. In comparison to common sleeping bags this shielding sleeping back is designed with generous measurements for a comfortable, permanent use.
The fabric Steel-Grey was chosen as it is, due to it´s stainless steel threads, considerably more durable and stable even with strong movement, than fabrics with silver threats would be. On the skin Steel-Grey feels a bit like a scratchy woollen sweater. Without inner cover or pyjama on, this could bother you.
