The sleeping bag is sewn from Steel-Gray. The zipper is collateral fitted at mid length and is silvered to provide an integrated shielding. The inner cover is non-removable and is made of cotton and polyester fabric. The inner cover will ensure your scratch free sleep, even without pajamas. 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-Gray was chosen as it is, due to its stainless steel threads, considerably durable and more stable even with strong movement, than fabrics with silver threads would be. On the skin Steel-Gray feels a bit like a scratchy woolen sweater. Without inner cover or pajama on, this could bother you.

Grounding

Shielding attenuation

The above mentioned screening attenuation values always apply to 1Ghz. The screening attenuation is regularly tested in our own EMC laboratory, we have measurement setups due to the following standards: ASTM D4935-10, IEEE Std 299-2006, IEEEE Std 1128-1998, ASTM A698/A698M-07.
