Microfibre is a revolutionary light and fine polyester fibre which is air-blown into the duvets outer casing for better loft and softness. It is designed to emulate the characteristics and feel of a duck or goose down duvet.
Tog rating for Microfibre Duvets are 13.5 tog and 10.5 tog.
What are tog ratings ?
A 'tog' is an industry standard name used for measuring the warmth of a duvet. The higher the tog rating, the warmer the duvet though the tog doesn't represent how heavy, light or thick the duvet may be. Lightweight duvets can insulate your body from the cold just as effectively as heavier ones. This is because some duvet fillings are better insulators than others.
Togs are measured in units of thermal resistance. For example, if a duvet had a tog rating of 4.5 then it would be more appropriate to be used in the summer months. At the other end of the scale, duvets with a tog rating of 13.5 or higher would be used in the colder months of the year.
