"Perfect for summer, the 4.5 tog rating and high quality synthetic fabric makes this hollowfibre quilt a superb addition to your home in summer when the nights are warmer. Each quilt comes filled with a special type of lightweight hollowfibre polyester. As the name suggests each strand of polyester is hollow, which traps air inside and retains heat. This synthetic filling is perfect if you or your family suffer from allergies and react badly to natural filled duvets. With a 4.5 tog rating, this duvet sits towards the bottom of the tog cosiness scale, making it ideal to use during Spring and Summer. The quilt is also machine washable so you can keep it fresh and cosy all year round. This quilt measures 260 x 220cm (102"" x 87"") and will fit super king sized duvet covers."
