Tog has a few different meanings. Your "togs" are just your clothes, in English. And tog has quite a few meanings in other languages.
Most commonly, tog also has a specific meaning with respect to thermal resistance: insulation. It's frequently used in Britain with reference to duvets (quilts, comforters) and other bedding: how warm do they keep you?
In the 1950s, a textiles research body, the Shirley Institute in Britain, developed the idea of tog as a measure of warmth, as an alternative way of stating the standard scientific measure (SI measure) m^2K/W. The idea was that tog ratings would typically be numbers between 1 and 15, and therefore easier to use. Togs are directly based on m^2K/W. One tog = 0.1 m^2K/W.
Tog can also be undertood as ten times the temperature difference (in °C) between the bottom and top of a bedding cover, assuming that the flow of heat is equal to 1 W/m^2.
Tog ratings in duvets decline over time, because of degradation in the density of the fibres as a direct result of daily use.
