73% Cotton 
27% Japanese Tsumugi Silk
 
Single weave - approx. 290g-300g/m2
 
Aspen Granite, grey japanese silk with white nubs on white warp.
Japanese tsumugi silk for me is the perfect ratio of softness and grip what I already said about Aspen Storm, Aspen Magnolia, Aspen Champagne, Aspen Flash and Aspen Heaven which are same blend.
Thin in hand but soft, cushy and thanks to nubs with excellent grip. Amazing grey with white nubs on warp warp looks like glitter but no! there is not, it's only illusion thanks to white nubs:)
