15.0 Tog Goose Down Duvets (WinterPlus)

15.0 Tog goose down duvets are the warmest, cosiest duvets we sell. In Germany, these high Tog rate duvets earn the distinction of being “Extra Warm”. We recommend them only for use in unheated rooms in cold climates and for those who feel exceptionally sensitive to the cold.

Available in all sizes from single to super king, WinterPlus duvets are the greatest testimony to the incredible insulating power of natural down. All our duvets are premium products with natural filling of at least 90% down and are produced in workshops which exercise extensive quality control and maintain high standards of excellence.

What makes a good WinterPlus down duvet?

Large Boxes

The size of the ‘boxes’ which make up a down duvet is a good visual indicator of its relative warmth. The more filling within one of these quilted squares (down chambers), the more efficient the insulation it provides. Therefore winter duvets will have fewer boxes than summer duvets. The boxes will in turn be much larger. In most cases a 135 cm x 200 cm WinterPlus duvet will have 24 boxes arranged in a 4 x 6 grid. Remember that fill power is the ultimate measure of insulation. Expressed in CUIN, the higher the fill power, the more efficient a duvet is at trapping warmth with the least volume of filling required.


Ventilation refers to the air permeability of a down duvet. WinterPlus duvets are sewn with baffles of 8 to 10 cm in length, which allows for more down to be inserted and enables the down to expand to its maximum capacity. These baffles also prevent air from escaping through the seams, making this kind of duvet incredibly warm.

Tog Rating

We use tog rating as an easy-to-understand measurement of insulation. A higher tog means that a duvet is suitable for colder environments. A tog rating of 15.0 indicates a toasty warm, WinterPlus duvet. More information can be found on our page about the tog system.

Down Quality

European Standard EN 12934 regulates the categorisation and naming of the filling material in bedding based on the proportion of new down and the types of poultry used. Only Class 1 down fillings may bear the quality rating “new”. All products on Downduvet.co.uk are filled with the best, Class 1 filling.


Experience shows that duvets with fabric of Ne 30 or higher are suitable for use by people with dust mite allergies. Premium down comforters have high-quality covers ranging from Ne 40 to Ne 155. On this website, you can see the Ne of each duvet under its product details. Additional protection is provided by duvets with the NOMITE label, which we recommend for allergy sufferers.
