Decent
Size: King (104" X 90"), Color: 05 - Khaki (No Comforter)
I purchased a bedsure duvet and duvet cover. King size. Should’ve purchased oversized king because it barely hangs over my bed. Highly disappointed with that, being that it’s not cheap when going duvet route, but otherwise happy with its comfort and texture.
