Two pieces in 100% TENCEL™ Lyocell: a 60″ x 90″ Twin duvet cover and one flanged 20″ x 26″ sham. What separates this from a cotton duvet cover is friction. Lyocell filaments are finer and the weave is tighter, so the surface glides under your hand rather than catching on it. That is the difference you feel on your cheek at 2 a.m., and it is why the fabric is kind to curly hair and to skin that marks easily. The fibre also handles moisture differently. It draws perspiration along the cloth and lets it evaporate, so the surface stays dry instead of holding a damp patch under your back — the practical benefit for hot sleepers. A button closure replaces the zip, so nothing snags or breaks. Eight interior ties hold the insert in place. The fabric has a naturally relaxed look; soft creases are part of the character, not a defect.
