The Danish Design County Luxury Deep Filled Duvets are filled with Supersoft Thermal Polyester Fibre to give even more softness, warmth and comfort. The removable cover is waterproof nylon with press-stud fastenings, which simply wipes clean with a damp cloth perfect for active and outdoor dogs. The duvets are fully washable and easy to dry as the Polyester Fibre will not absorb water.
