The term "tog" refers to a unit of measurement used to indicate the thermal insulation of a fabric, particularly in bedding and clothing. It helps consumers understand how warm a product will keep them, with higher tog ratings signifying greater warmth. Tog ratings are commonly found on items like duvets and sleeping bags. In the context of bedding, a duvet with a tog rating of 4.5 is suitable for summer, while a rating of 13.5 is ideal for winter use. Understanding tog ratings can assist individuals in selecting appropriate items for their comfort and climate needs.
