The Luxury Light Goose Down Quilt has a 4 TOG warmth rating, making it perfect for the warmer seasons. TOG ratings are an international standard that determine the thermal insulation of a quilt’s filling; the higher the TOG rating, the warmer the quilt. It holds 80% minimum goose down and are constructed with down-proof cotton japara casing. Japara is a stable, closely woven fabric which encases the feather and down, preventing the filling from penetrating the casing. Our Luxury Light Goose Down Quilts are ideal for summer. Alternatively, for cool months and cold sleepers, the quilt features a tie system at each corner allowing for quilt pairing.
