It’s a silver-plated (non-allergenic) bobbinet fabric with conductive surfaces. Woven for durability, the fibres used are folded long staple Egyptian cotton, Lycra, polyamide, polyester, silk, and polypropylene.
 
It is a very light grey colour (which is the reason for its high transparency), lightweight, and is easy to sew and process.
