The Elsing Duo Duvet is a summer, transitional, and winter duvet rolled into one. Made from a high-performance polyester material, the fibres in this duvet are hollow, helping to trap heat, while remaining super light and fluffy. The Elsing consists of two separate duvets of varying thicknesses: the summer layer is super light and suitable for hot nights, while the second layer is slightly thicker, ideal for transitional seasons. In winter, button the layers together to create one super warm and cosy layer for extra cold nights. Both duvets have a 100% cotton shell and are finished with a Mako percale piping. The Elsing comes with a zippered dust bag, perfect for storing the layer that's not in use.
