Very soft wool/tencel blend stretch jersey, the colour is a relatively dark carbon grey. It is just barely translucent when unstretched (more translucent if stretched), and drapes very well. It is very light and feels cashmere-soft against the skin. The surface is just slightly fuzzy. Suitable for cool weather clothing: drapey tops, thin turtlenecks, tees, kids wear, and knit camisoles and light cardigans for air-conditioned environments. Two other colours are available separately (shown in the second-last photo).
Wool is naturally odour-resistant, breathable, moisture-wicking (so it dries really quickly), and temperature-regulating. I personally can't wear regular sheeps wool, but I find the wool fabrics in the shop comfortable to wear and not scratchy at all - still, please buy with care if your skin is very sensitive.
