Three pieces in 100% TENCEL™ Lyocell sateen: a 108″ x 92″ King duvet cover and two 20″ x 36″ shams. The first thing you notice is how it moves. Lyocell filaments are far finer than cotton staple, so the cloth falls in soft liquid folds instead of standing in stiff creases, and the sateen weave lays those filaments in one direction so the surface catches light across a long, unbroken sweep. That is the soft sheen you see on the folds in the photos, not a coating or a polish. It sleeps cool for the same reason it drapes: the fibre draws moisture off the skin and spreads it across the surface to evaporate, so you are not lying in a damp patch by morning. A hidden button closure keeps the opening invisible, eight interior ties anchor the insert, and the set ships in a printed box with a fabric bag. Duvet insert not included.
