Our 4.5 tog duvet is light and airy, filled with a combination of natural feathers and down clusters. These clusters help to provide some warmth but without the excess weight, allowing the duvet to breathe and assist with a peaceful night’s sleep. This unique design duvet is made especially for the warmer Spring and summer months with high-quality filling which offers a lightweight duvet.Along with the filling, the 100% cotton casing is a very breathable casing which helps circulate air through the night and prevents overheating and sweating which can create an unhealthy, uncomfortable sleeping environment. Boasting a 100% cotton cover and a 250 thread count, this duvet is a must-have for those hot summer nights! Please note: This is a natural feather product, which will have a slight odour. This can be reduced by airing the product out for at least 48 hours before first use and over time the smell will fade.
