The pure linen cotton of this duvet cover is woven from fibers of an environmentally friendly plant. Unsurpassed for centuries for its natural comfort, durability, and elegance, finely woven linen cotton fabric allows your skin to breathe while absorbing moisture, which evaporates, rendering these sheets both cool and calming. Over time, linen cotton becomes softer and even more comfortable to touch. It's even non-allergenic and antibacterial.
