Generally speaking, the total ,heat, loss test has an inverse relationship with the thermal ,protective, performance (TPP) rating of a ,three,-,layer, system. This actually makes sense when you consider that the way to obtain higher thermal performance is to increase the thermal insulation, while the way to allow more ,heat, to escape from a garment would be to decrease the thermal insulation.
